Dells XPS are made of magic. [long story, major fuckup, 10k+ damages]
It all started in December. One morning I was late to work, drove there as fast as possible. (I live like 3 minutes away so me being late really meant *late*) Parked my car in a secluded car park, grabbed my backpack and ran to work. The car park is like 100 meters away from work so I took my feet into my hands and ran. Next thing I know my heels loose all grip while I go down a small slope and I drop on my back full force. On a sharp edged stone. With only my 1700$ XPS in it. Fuck.
I paniced, but got up and ran to work. I checked on the notebook, praying it would boot. It booted! Holy shit. I flipped the notebook and saw two small dents in the aluminum shell. I was thorougly impressed. I later discovered that it left a small shadow on the display, but given what a hit that was (I am not exactly a lightweight), impressive would be a massive understatement.
Fast forward to February, I am weighing my options to get the screen replaced maybe, as damage on my hardware (even if neglectable) triggers some sort of OCD and makes me feel bad 24/7. Also my laptop tends to shut off from time to time, looked into the Event Viewer and saw kernel panic. I figured that the battery probably still took a hit and that it drops voltage from time to time and the kernel assumes a critical situation, thus shutting off.
It stayed quite snowy in Austria up until March, so occasional snowing wasn't rare. Got out of work one day, saw it snowed a bit. Whatever. I had my moms car at the time, so I tried if it would slide a bit if I donut on the now (5pm) empty parking space. Nothing. Drove done a small hill, ABS triangle lit up red (board computer can't outbalance the snow). I drove out to the main street where everything was salted and drove along towards my house. Took a turn into my street, accelerated for a bit and then went off the gas so the car would smoothly drive along with the speed slowly degrading. So I went off the gas and noticed I was a bit to the right, no wonder, centrifugal forces.
*steers left*
"Huh seems like I need a bit more"
*car still doesnt move much*
"What the- go to the left!"
*steers left hard*
"Fuck that wall is coming closer"
*Breaks*
*car doesnt break*
"FUCK FUCK FUCK FUCK!!!"
Everything got quiet in seconds, me waking up to an open airbag, ripped pants, a hurting wrist, the radio somewhere on the ground and fumes that smellt like burning wires. I grabbed my backpack that was now somewhere on the floor instead of on the seat and ran outside, tears in my eyes and the phone on my ear calling my mom. I walked inside as she walked outside, hearing a weeping scream that I haven't heard from her since I am alive. While walking inside I noticed my backpack was wet on the bottom, my 2 litre water jug shattered when my backpack hit the dashboard. I tried to stay calm and act rational, knowing that every second counts when It comes to water damage. I hastely searched for some rice and a bag to put my laptop into, stuffed the bag with both and went outside. The car was totaled, my mom pissed and crying. And I was in shock, sad, angry and hurting.
I kept the laptop on my heater for a few days, bagged in rice. I dared to try a boot after a while and you wont believe me, it fucking booted. Even the keyboard backlight worked, just the screen was obviously broken in the back (no color distortion or bad pixel rows though!!) and the aluminum shell had a dent on the front. I talked with Dell Support a few days later, asking if it would be ok to open the XPS up so I could drain all of the water. She said yes thats fine, as long as I dont touch anything or screw around with it.
She said I can send it in and get it checked, but the pickup and analysis will cost 150$ and I can go from there.
I sent it in and estimated that, because battery, screen and other things probably needed changing, it will be around 900$.
Got a call a few weeks later:
"Hello beggarboy, the repair team reported back to us and said that they will have to replace everything, which will be 1700$."
"Fuck... Buying a new one is cheaper.."
"Yeah I know I am sorry about that, I can offer you a voucher so you can buy a new one for 250$ off if you would prefer that"
"Sorry but I will need some time to consider"
"I understand."
The agent clearly noticed I was bummed about it.
After going back and forth what to do I got another call a few days later.
"Hello beggarboy, we talked a few days ago. I have good news"
"Hello, yes, speak up?"
"I was able to get a special offer for you after putting in a few words..."
The next thing she said seemed unreal to me.
She was able to cut 600$ (!!!), making the new offer 1100$, instead of 1700$ or a new one for 1500$. I figured the reason she probably did that was because I am always very polite with support members. Always.
My XPS is back and healty again.
Thank you for taking the time to read this.
Dells XPS are made of magic.13 -
I have this little hobby project going on for a while now, and I thought it's worth sharing. Now at first blush this might seem like just another screenshot with neofetch.. but this thing has quite the story to tell. This laptop is no less than 17 years old.
So, a Compaq nx7010, a business laptop from 2004. It has had plenty of software and hardware mods alike. Let's start with the software.
It's running run-off-the-mill Debian 9, with a custom kernel. The reason why it's running that version of Debian is because of bugs in the network driver (ipw2200) in Debian 10, causing it to disconnect after a day or so. Less of an issue in Debian 9, and seemingly fixed by upgrading the kernel to a custom one. And the kernel is actually one of the things where you can save heaps of space when you do it yourself. The kernel package itself is 8.4MB for this one. The headers are 7.4MB. The stock kernels on the other hand (4.19 at downstream revisions 9, 10 and 13) took up a whole GB of space combined. That is how much I've been able to remove, even from headless systems. The stock kernels are incredibly bloated for what they are.
Other than that, most of the data storage is done through NFS over WiFi, which is actually faster than what is inside this laptop (a CF card which I will get to later).
Now let's talk hardware. And at age 17, you can imagine that it has seen quite a bit of maintenance there. The easiest mod is probably the flash mod. These old laptops use IDE for storage rather than SATA. Now the nice thing about IDE is that it actually lives on to this very day, in CF cards. The pinout is exactly the same. So you can use passive IDE-CF adapters and plug in a CF card. Easy!
The next thing I want to talk about is the battery. And um.. why that one is a bad idea to mod. Finding replacements for such old hardware.. good luck with that. So your other option is something called recelling, where you disassemble the battery and, well, replace the cells. The problem is that those battery packs are built like tanks and the disassembly will likely result in a broken battery housing (which you'll still need). Also the controllers inside those battery packs are either too smart or too stupid to play nicely with new cells. On that laptop at least, the new cells still had a perceived capacity of the old ones, while obviously the voltage on the cells themselves didn't change at all. The laptop thought the batteries were done for, despite still being chock full of juice. Then I tried to recalibrate them in the BIOS and fried the battery controller. Do not try to recell the battery, unless you have a spare already. The controllers and battery housings are complete and utter dogshit.
Next up is the display backlight. Originally this laptop used to use a CCFL backlight, which is a tiny tube that is driven at around 2000 volts. To its controller go either 7, 6, 4 or 3 wires, which are all related and I will get to. Signs of it dying are redshift, and eventually it going out until you close the lid and open it up again. The reason for it is that the voltage required to keep that CCFL "excited" rises over time, beyond what the controller can do.
So, 7-pin configuration is 2x VCC (12V), 2x enable (on or off), 1x adjust (analog brightness), and 2x ground. 6-pin gets rid of 1 enable line. Those are the configurations you'll find in CCFL. Then came LED lighting which required much less power to run. So the 4-pin configuration gets rid of a VCC and a ground line. And finally you have the 3-pin configuration which gets rid of the adjust line, and you can just short it to the enable line.
There are some other mods but I'm running out of characters. Why am I telling you all this? The reason is that this laptop doesn't feel any different to use than the ThinkPad x220 and IdeaPad Y700 I have on my desk (with 6c12t, 32G of RAM, ~1TB of SSDs and 2TB HDDs). A hefty setup compared to a very dated one, yet they feel the same. It can do web browsing, I can chat on Telegram with it, and I can do programming on it. So, if you're looking for a hobby project, maybe some kind of restrictions on your hardware to spark that creativity that makes code better, I can highly recommend it. I think I'm almost done with this project, and it was heaps of fun :D12 -

Finally got time to share my new laptop. I love its rgb backlight keyboard. I will buy a NVMe SSD and second monitor asap.6

I'm installing Gentoo on a keyboard. Not even kidding.
.
.
.

.. well, clickbait aside, it's a laptop that's been turned into a keyboard on steroids, its backlight broke so I had to remove the display until I get around fixing that.. but its keyboard is so good. They don't make them like that anymore... So yeah 🙃 turning it into some kind of controller for the other desktops. Tomorrow (or rather, in half a week when the Gentoo installation is finally complete) I'll be SSH'ing into my keyboard 😛
The finish line for my Linux journey is starting to get in sight 😄4 -
Long rant ahead.. 5k characters pretty much completely used. So feel free to have another cup of coffee and have a seat 🙂
So.. a while back this flash drive was stolen from me, right. Well it turns out that other than me, the other guy in that incident also got to the police 😃
Now, let me explain the smiley face. At the time of the incident I was completely at fault. I had no real reason to throw a punch at this guy and my only "excuse" would be that I was drunk as fuck - I've never drank so much as I did that day. Needless to say, not a very good excuse and I don't treat it as such.
But that guy and whoever else it was that he was with, that was the guy (or at least part of the group that did) that stole that flash drive from me.
Context: https://devrant.com/rants/2049733 and https://devrant.com/rants/2088970
So that's great! I thought that I'd lost this flash drive and most importantly the data on it forever. But just this Friday evening as I was meeting with my friend to buy some illicit electronics (high voltage, low frequency arc generators if you catch my drift), a policeman came along and told me about that other guy filing a report as well, with apparently much of the blame now lying on his side due to him having punched me right into the hospital.
So I told the cop, well most of the blame is on me really, I shouldn't have started that fight to begin with, and for that matter not have drunk that much, yada yada yada.. anyway he walked away (good grief, as I was having that friend on visit to purchase those electronics at that exact time!) and he said that this case could just be classified then. Maybe just come along next week to the police office to file a proper explanation but maybe even that won't be needed.
So yeah, great. But for me there's more in it of course - that other guy knows more about that flash drive and the data on it that I care about. So I figured, let's go to the police office and arrange an appointment with this guy. And I got thinking about the technicalities for if I see that drive back and want to recover its data.
So I've got 2 phones, 1 rooted but reliant on the other one that's unrooted for a data connection to my home (because Android Q, and no bootable TWRP available for it yet). And theoretically a laptop that I can put Arch on it no problem but its display backlight is cooked. So if I want to bring that one I'd have to rely on a display from them. Good luck getting that done. No option. And then there's a flash drive that I can bake up with a portable Arch install that I can sideload from one of their machines but on that.. even more so - good luck getting that done. So my phones are my only option.
Just to be clear, the technical challenge is to read that flash drive and get as much data off of it as possible. The drive is 32GB large and has about 16GB used. So I'll need at least that much on whatever I decide to store a copy on, assuming unchanged contents (unlikely). My Nexus 6P with a VPN profile to connect to my home network has 32GB of storage. So theoretically I could use dd and pipe it to gzip to compress the zeroes. That'd give me a resulting file that's close to the actual usage on the flash drive in size. But just in case.. my OnePlus 6T has 256GB of storage but it's got no root access.. so I don't have block access to an attached flash drive from it. Worst case I'd have to open a WiFi hotspot to it and get an sshd going for the Nexus to connect to.
And there we have it! A large storage device, no root access, that nonetheless can make use of something else that doesn't have the storage but satisfies the other requirements.
And then we have things like parted to read out the partition table (and if unchanged, cryptsetup to read out LUKS). Now, I don't know if Termux has these and frankly I don't care. What I need for that is a chroot. But I can't just install Arch x86_64 on a flash drive and plug it into my phone. Linux Deploy to the rescue! 😁
It can make chrooted installations of common distributions on arm64, and it comes extremely close to actual Linux. With some Linux magic I could make that able to read the block device from Android and do all the required sorcery with it. Just a USB-C to 3x USB-A hub required (which I have), with the target flash drive and one to store my chroot on, connected to my Nexus. And fixed!
Let's see if I can get that flash drive back!
P.S.: if you're into electronics and worried about getting stuff like this stolen, customize it. I happen to know one particular property of that flash drive that I can use for verification, although it wasn't explicitly customized. But for instance in that flash drive there was a decorative LED. Those are current limited by a resistor. Factory default can be say 200 ohm - replace it with one with a higher value. That way you can without any doubt verify it to be yours. Along with other extra security additions, this is one of the things I'll be adding to my "keychain v2".11 -
I decided to fix my car after car mechanic gave up... The backlight was blinking even the car was locked and turned off in the parking. Took me 4 days to figure it out. What I realised is that we are pushing tech to places where tech and electronics shouldn't be... My next car will be 1972 ford c, it doesn't have any of these modern problems.14

hey ranteros! i like to dream and i know many of us dream of a nice machine to do anything on it, if you want to post the specs of your ideal build(s) (even a laptop, pre-built pc, space gray macbook pro... doesn't matter). and your current one.
here's mine:
ideal: {
type: desktop-pc,
cpu: intel i7-8700K (coffee lake),
gpu: nvidia geforce gtx 1080ti,
ram: 32gb ddr4,
storage: {
ssd: samsung 960 evo 500gb,
hdd: 2tb wd black
},
motherboard: any good motherboard that supports coffee lake and has a good selection of i/o,
psu: anything juicy enough, silver rated,
cooling: i don't care about liquid cooling that much, or maybe i'm just afraid of it,
case: i accept any form factor, as long as it's not too oBNoxi0Us,
peripherals: {
monitor: 1080p, maybe 1440p, i can't 4k because of the media i consume (i have tons of shit i watch in 720p) + other reasons,
keyboardmousecombo: i like logitech stuff, nothing fancy, their non mechanical keyboards are nice, for mice the mx master 2 is nice i think, i also don't care about rgb because i think it's too distracting and i'm always in darkness so some white backlight is great
},
os: windows 10, tails (i have some questions about tails i'll be asking in a different post,
}
i think this is enough for ideal, now reality:
current: {
type: laptop,
brand: acer (aspire 7736z),
cpu: pentium dual-core 2.10ghz,
gpu: geforce g210m 2gb (with cuda™!),
ram: 4gb ddr3,
storage: hdd 500gb wd blue 5400rpm (this motherfucker stood the test of time because it's still working since i bought this thing (the laptop as it is) used in late 2009 although it's full of bad sectors and might anytime, don't worry i have everything backed up, i have a total of 5 hdds varying from 320gb to 1tb with different stuff on them),
screen: 17 inch hd-ready!!! (i think it's a tn panel), i've never done a test on color accuracy, but to my eyes it's bright, colorful, and has some dust particles between the lcd and backlight hah,
other cool things: dvd player/burner, full-sized keyboard with numeric keypad, vga, hdmi, 4 usb ports, ethernet, wi-fi haha, and it's hot, i mean so hot, hotter than elsa jean and piper perri combined,
os: windows 10, tails
}
if you read this whole thing i love you, and if you have some time to spare on a sunday you can share your dream rig and the sometimes cruel current one if you dare. you don't have to share them both. i know many will go b.o.b and say "what you're hoping to accomplish, i already did bitch.", that's cool as well, brag about your cool rig!6 -
Idiot mode: on
It's bad when you realize you are the most idotic person you know. I just bought a wifi card replacement for my laptop only to find out that one of the screws on its back was completely unscrewable. I foolishly decided to force my way through by forcing the plastic. I tought I got away with it as I only damaged a plastic support tighten to the laptop base but now, my laptop screen isn't showing anything.
When I first booted it up after this, it was working, but it started showing troubling signs shortly after. Now, all I can get out of it is a completely black screen, no backlight at all.
What should I do? 😥9 -
I like lying in the dark with my laptop with keyboard backlight enabled just to look at the keyboard.4

One of my hobbies is to repair stuff.
In front of me is a Xiaomi Notebook air 13.3", a very nicely build device.
But it's driving me nuts, the screen is completely glued onto the front glass.
How the fuck am I supposed to exchange that display with a new one?
The main problem with those devices seems to be the display-cable in the hinge.
It might short 3.3V to 19V backlight, killing the display, the hdmi controller and the audio-chip.
2 ez fixes so far, but that fucken display.
And the absolute worst is that there are 0 official replacement parts available for any of the Xiaomi notebook's.
The fuck! -
Finally, fucking finally I fixed a damn bug that seems to be freaking popular on asus machines. This damn bug captures the fn keys needed to regulate the screen brightness.
All tools that display your keypresses didn't find them at all and I had a pretty tough time find the source of problem.
You can create as many arch memes as you want but you cannot deny that the they are truly MVPs imo.
Today I also:
* Fixed and refactored a bit of code
* added shortcuts for volume and keyboard backlight control
* Installed lots of fonts
* Got Steam to run
* Found out the meaning behind the Arch linux
* Felt disgusting using windows 10. Learned that 10 stands for the number of minuts before I must vomit 🤢
* Learned a bunch of linux stuff
But most importantly

After spending 3 days trying to install Ubuntu on an XPS 15, I am ready to give up.
It's just not possible to install Linux on it, it will either freeze on install, freeze on boot, freeze on shutdown, or freeze in the middle of all of these.
Using the dedicated GPU is impossible since Nvidia are fucking retards. The touchpad constantly stops working.
The internet is filled with distro respins and 500 page long manuals on how to get things working on an XPS 15, but nothing works properly. Even the fucking keyboard backlight doesn't turn on without writing 100 things in GRUB
For those saying Linux is "faster" and "more reliable", well fuck right off, my unlit keyboard says otherwise, I'm done.7 -

Accomplishments of today:
- Wrote a small battery level script for my polybar config to print "AC" as battery level if the battery is removed, rather than having it continue to display the level the battery was at when I removed it (how the polybar module does by default)
- Small bluetooth detector script (checks if bluetooth is on or off, and if it's connected to anything)
- Wrote another script to turn my screen's backlight off when the lid closes and back on when it opens again (literally just finished this one maybe 5 minutes ago)
- Finally fixed an issue with the volume level module on my polybar config, where it increments in levels of 5%, but it would always be on like 94 or 89, rather than 95 and 90 (weird to explain)
Pretty accomplished with myself, they were all minor differences that most people wouldn't really think about, but I'm happy about them. -

The display power savings feature on Intel GPU drivers is retarded. It reduces backlight brightness when you're viewing dark content and pumps it back up when you have something white on the screen. This is the complete opposite of what you need for keeping the image viewable with minimum backlight brightness.
The dark parts of the dark image can be kept the same brightness by reducing the backlight, but the white text you're reading will actually be darker, so you need to manually set the display brighter. And then you need to reduce brightness when you switch to a white window because now that's too bright. And as a bonus, the backlight brightness will keep adjusting when you change windows, which is super distracting.1 -
So I wonder if anybody on here has ever come across the LG G3 flickering screen issue.
I bought a LG G3 about 2 years ago. Fantastic phone.. Until all the issues started appearing.
First of all, the glass started lifting off on the left side of the phone, exposing the backlight layer, because the phone somehow managed to bend (insert iphone joke) inside my pocket. I was okay with it since it was a minor visual thing and didn't affect anything.
About 6 months ago the phone started lagging like crazy, and it kept getting worse and worse. It's so bad right now that Twitter will rarely fullscreen images, apps crash all the time, and occasionally the phone freezes to the point where it won't even react to the lock button.
About 2 weeks ago I started getting messages that my sim card was removed, and the phone starts rebooting itself. This would sometimes happen 10 times a day.
I was already pissed at all of these issues and in a desperate need of a new phone, but on Sunday a brand new issue appeared!
The phone's display randomly shut off, then wouldn't want to turn on, and occasionally turn on just to fade out or flicker away.
I of course went to google to see if anybody else has this issue... And it turns out that youtube is full of videos about it. Apparently the overheating issue these phones have slowly ruins the solder on the chips, which in turn creates a poor connection and causes these issues. The only way to solve it seems to be to reflow the chip, but others that tested that only got it to work for around 2 weeks before the issues started reappearing. I haven't tested it myself yet, but after disassembling, fucking around with it, and putting it all back together 3 times I sort of got it to work to the point where I can use it for several minuted before the displays fails. While writing this rant the display only quit on me once at the very beginning.
What I'm wondering is, why is it that nobody at LG decided to address the heating issue by perhaps throttling the CPU more? And I heard the G3 isn't the only LG phone with these issues?
This crap made me lose all my trust in the company. I wanted to upgrade to a G6 or V30, but because of this crap I think my next phone might be a Xiaomi.
This rant is now so long that it's barely even a rant or on topic. I think I should end it here since I have nothing more to say other than the LG G3 is a beautiful but crap phone, oh, and the new iPhone 8 is a flop9 -
So I got the new macbook pro 15 with touchbar .... this is my first macbook that I have ‚issues‘ with.
* the new butterfly keaboard doesnt feel as good as the old one
* ... abd its friggin loud!
* the keyboard backlight just randomly drops out and forces me to cold reboot WTF??
* they bigger left/right cursor buttons make it so hard to feel where you are, that I constantly confuse up and down
* the touchbar is basically unusable for a keyboard centric person like me. It forces me too look down to the keys!
* I constantly hit the esc bc im used to have one finger there to hit it if needed, but now im forced to hover it bc otherwise it is pressed
* and why of fucking why did apple remove magsafe??? Now i dont even see anymore if is is being charged without turning the screen on
* i hate the usb ports too, why not even add a free usbc to usba port? (Well, i guess bc it would make the macbook even more expensive... free wouldnt be free anyway i guess)
It is way more powerful though, but the time i would buy a personal one is over and will probably never come back.
Im a happy hackintosh user btw 😅3 -
So guys, I'm going to buy a new Notebook for coding and multimedia usage. The question that bothers me the most right now:
Is there a huge difference between IPS and Backlight LED Displays? Anyone got some experiences regarding this topic? -
Looking for nice mechanical keyboards with underglow/sideglow or backlight, any recommendations? Photo for attention featuring Jian Keyboard. Budget: 175$ including shipping to Poland, can be cheaper because I'd probably change keycaps as soon as it arrives. Max. 65% keyboard because I would carry this to my school huh.
