Search - "battery failed"
-
I was in a public place on my laptop, and my laptop went into hibernation to save battery. I switched it back on and then the laptops BIOS came up saying that the battery was critically low, nothing bad here.
Instead of clicking continue, I decided to press "Diagnostics" instead. The diagnostics immediately began to run in the BIOS.
The screen began to show different coloured bars and patterns, obviously a screen test. Then a prompt appeared asking me if coloured bars were displayed. The options were yes and no, and a button saying "Exit" in the top right. Me, not wanting to do a full diagnostics on such a low battery, pressed exit.
The screen turned black, and then flashed red. The beeper on the motherboard began to beep at an ear-piercing volume. It sounded as if it was a bomb about to go off. Everyone around me stared and some people began to even panic. I tried switching it off by holding the power button but nothing was happening. People were just staring all around me.
After about 10 seconds, the beeping stopped and the screen displayed an error message similar to this:
"CRITICAL ERROR: Monitor test FAILED.
No user input was provided."
Moral of the story: Make your program account for all possible options.11 -
1. I wish that people start taking back their device ownership. Right to repair is an extremely important thing. Like that Nexus 6P that I've recently repaired by jamming another battery into it, now it's at 110-ish% health according to AccuBattery. And it cost me.. €10 or so? All the while if I wasn't able to get in there, it would've been a €120 paperweight (and that's not even considering the €300-ish (? Someone please fill me in on that) price it retailed at back in 2015 when it was a flagship).
(edit the so many'th: according to https://express.co.uk/life-style/... the base model was apparently £449 at release, haven't been able to verify it though.. point is, a paperweight at such prices would've been quite a bummer, I mean for me it was even one given that it failed a mere few months after purchase for €120.. €40/m for a phone ain't nothing :/)
Right to repair is an extremely important thing, and the ability to do so shouldn't ever be impeded. Users should become able again to service the devices that they own.
2. I wish that people start caring about their privacy again. Google and Facebook and the likes are large companies, but at the end of the day, that's all they are. Large companies. And they're hungry for your data, not because they're selling it, rather because they're collecting it to an extent which they shouldn't. Over at DDG (https://spreadprivacy.com/duckduckg...) they explain a very much viable alternative revenue model pretty well. Additionally, there's several tools which you can use to limit the amount of data that's being collected about you. These include but are not limited to Firefox, NoScript, ad blockers (I personally use uBlock), a trustworthy VPN (ideally one of your own), and Tor.
3. I wish that software would become less inefficient. It really pains me to see that applications with functionality that could be implemented in a couple of MB at most come at a size of several hundreds of MB. 1% efficiency, even the inefficient as fuck tungsten light bulbs weren't that awful!!! Imagine what could be done with all the hardware we have available nowadays, if every piece of software would be around 80% efficient as is a common norm in electronics. Just looking at Linux which is still in many ways convoluted, modern desktops with a couple hundred MB of RAM usage? You've got it! So why can't OS's like Windows (although I have to say, huge improvements have been made there over the last few years) and browsers like Firefox and Chrome be more like that? I really don't understand.
There's several more wishes I have of course, but those are the most important ones.. hopefully I'll be able to see at least one of them come true during my life.10 -
TL;DR: check polarity before plugging your DIY circuits into others!!!
*goes off to watch some Lucky Star and drink some booze*
*notices phone battery dying after 3rd pint*
But my charging cable that Huawei delivered with this thing is way too short... Well that ain't no problem, I can make one of my own 😎
But I'm tipsy.. sound I really enter the workbench in this state?
*goes off to build a charging cable anyway*
But what was USB-A male connector's polarity again? Oh, there's the fan's USB connector that I've made in the past. Let's check on that one. So, left is positive and right is negative?
*solders the wires on*
Snip, strip, stick, done! Well that was easy. I guess that all those failed soldering attempts and lost pads in the past as a means of training did pay off in the end!
*plugs phone into Raspberry Pi media center through new charging cable*
Strange sounds coming from the speakers.. well that's odd. Reverse polarity or maybe the Pi can't handle a 1A load from my phone?
*plugs phone into the 5V 5A charging hub that I've made earlier*
That oughta do.. current limits should be no more in that thing.
*charging hub makes high-pitch noise similar to the Pi speakers*
Definitely a reverse polarity, isn't it :') let's check on the Gargler...
Oh shit! It is a reverse polarity mistake!!! Should've checked this earlier >_<
*resolders wires properly*
Alright, finally done.. as I'm writing this post, my phone's charging from the Raspberry Pi through my fixed charging cable now...
Lesson learned. Always check on the internet what the pinout is before soldering anything, don't solder while tipsy, and be fucking grateful that this phone has reverse polarity protection in it.
Nexus 6P with all its shortcomings regarding power delivery and battery management, luckily it's got reverse voltage protection features built-in. Otherwise it might've costed me my phone. Always double-check before plugging anything into something else!!!5 -
Did I every tell you about that time I scared a boss (not mine, he was in the room) so much, that he was to scared to enter my office for the next couple of weeks? 😅
Good times 😊
Tl;dr: He was the reason I was working at max capacity and then he started complaining that shit wasn't working.
Full story:
I was out of office, building up a new site. I was the only IT working that day, others were out on vacation.
Suddenly I start getting flooded with calls from other sites, that nothing works. It is so bad, that my boss can't reach me on the company phone, so he calls me on my private phone.
Apparently all the servers are down.
So me into a taxi, heading for the main office.
When I get there I just start booting the servers on by one, because they didn't like that they had lost power. While I'm working, my boss is standing there, ready to help.
Another boss enters the office and goes: "I can't access Navision". To which I quickly reply something like: "Well everything is down, I'm the only one who can fix it and I'm working as fast as I can".
Two weeks later, another employee tells me, that the other boss has been running all his equipment off a battery backup, since the failure, because his power cord failed. He spilled a cup of coffee on it and therefore was the reason, that all the servers lost power (bad setup, I know). And apparently I was so frightening that he didn't have the courage to ask for a new power cord 😂
Best thing was that my boss never stopped me or told me that I did something wrong.2 -
me@termux $ su -c pm list packages
android.os.DeadObjectException: Transaction failed on small parcel; remote process probably died at [...]
Hmm, strange.. wasn't that the proper command? 🤔
Maybe it's SELinux that's at it again? It's giving permission errors with /sys/class/power_supply/battery/capacity as well, which can only be solved by disabling SELinux it seems.
me@termux $ su -c setenforce 0
me@termux $ su -c pm list packages
(Gives list)
So it was SELinux after all.. FUCKING PIECE OF SHIT!!!2 -
It is time... to rant about macs!
No, seriously - I had such a different experience about which not many talk in real life or pretend that it never happens....
Model: 2015 mid MBP 15" with second to highest specs (don't have dedicated gpu).
Rattling fucking toy.... Yea, it rattles! If you shake/move ir sit in trait/bus - it non-stop rattles as a fucking toy. Worst part? It's confirmed issue by apple and it manifacturing issue that they are not keen on fixing!!!! WTF? We have 4 macs in our office - all of them fucking rattles... God help me how annoying that is. (Lose LCD control panel that unsticks from glue. Replacing it solves the issue for 1 month if you carry it anywhere).
Constant fucking crashing/updates.... Every morning I wake up and don't have an app that requires confirmation for restart - it's restarted. YAY, turning on all apps once again.... Why you may ask? Well, because if you tinker with software in any way - it fails to update it and hell breaks lose. It's been a long time since High-Sierra came around and the issue is still there (not running Mojave as it conflicts with soft I have... Woo!). Tried few times - updates fail. Resolution? Reinstall OS!
OS conflicts with applications - damn... People told me it works out of the box.... Yeah, as long as you don't upgrade the OS - then it breaks. Why? Well, because.
Piece of shit power supply. With 4 of our office power supplies - 2 of them failed twice withing warranty and once afterwards... Really? Not to mention that all 4 are starting to shear the sleeve or already did (mine is just wrapped with white electrical tape to give it a support... lol).
Bluetooth - who the hell needs that in mac, right? Well, people do. To start with - it conflicts with 2.4GHz wireless network - you might have one of those and not both at the same time. Next thing is using a device that needs constant connection (mouse, headphones, keyboard - non apple branded) - shit... They can't stay connected for more than an hour without any issues... Constant battle to re-connect it, to re-pair the device and all due to smart apple bluetooth settings. Hell, my mouse (logitech MX master) was even printing random symbols in some applications if moved. All of the issues went away after using a bluetooth dongle... WOO!!!!
Xcode... Ahh, you may never prepare your mac if you don't download 17GB of fucking xCode libraries that enables some tools to be installed/runned as you can NOT get them in any other way and you have to install full xCode software in order to get them... YAY! 17GB wasted on my 256GB SSD that I can't upgrade. GREAT!
OsX applications - ah, don't get offended but if you are using them and you are fine with them - you are probably a monkey that loves being told what to do. You can't customise any actions, you can't configure it the way you like - either you accept their default workflow or go kill yourself. Yep... Had issues with calendar, mail, iMessages, safari... None of them fit my needs :)
Resolution scaling... Fucking hell, the display is 2880 x 1800 but all you let me to use is 1440x900 without scaling? Am I blind to you? Scaling the resolution means that you are fucked if some applications don't support scaling very well. Looking at you Jetbrains - your IDES suck at scaling and slows down the pc to a potato....
Now the pros - keyboard is way better than the new ones, trackpad is GREAT - no need for mouse (using it on external 4k displays only), the battery life is great - getting around 6h of continues development time, 8 if using sublime instead of phpStorm and well, that's about it...
To clarify:
I've bought this device due to the fact that at that time mac and windows pc's with similiar specs costed the same while windows pc sucked with their quality of the device and trackpad... Now the situation is better and when time comes for a next upgrade - it's going to be one of these:
Razer Blade 15, Dell XPS 15, Lenovo Carbon X1 series.
And of course - LINUX. I've had enough issues with windows, and had enough of retardness of apple ecosystem, so switching it is a must for me.
Disclaimer: I might be an unhappy customer, a bit picky but I'd like my device to be setted up as I like and continue to have that until I don't like, not until the company decides to break it. Not to mention that paying almost a yearly salary in my country for one device - I'd expect it to be at least reliable and work without issues....
Rant over.
ps. You can disagree with me, this is my personal experience with MBP over the last 3 years :)8 -

My new HTC smartphone hates me.
First it started to shut down all of the sudden yesterday night, when I was solving quadratic equations on my laptop.
I thought that it might be due to low battery. So I have restarted it. After putting itself into a bootloop for 4 start sequences, it was able to fully start to the page where it told me to enter the security pin to decrypt my files. I also had 30 attempts left. Like a ransomware.
I was like "tf I didn't set anything up".
So I decided to use my first attempt as I had 30 attempts left.
I entered the pin (I can swear that it's correct) and it told me that it has to wipe the /data partition.
I did that. I pressed that button. After waiting for 30 minutes I gave up and rebooted into the bootloader.
Bootloader -> Download Mode -> wipe /data (stock rom + stock recovery btw.)
Some error with "e: mount /cache failed[...]e: mount /data failed"
So, I tried using the adb sideload - no success.
Fastbooted into RUU Mode - HTC keeps rebooting itself into the RUU Mode - no success
Tried to flash the firmware and twrp recovery from Download mode - no success
Then I tried to flash all these things from the sd card - no success
Searched for revolutionary (I know this from my old HTC sensation device).
It wasn't big of any help.
Then someone on xda recommended htcDev (htc's <b>developer-friendly</b> lol site)
I followed every step. Everything seemed to be okay.
I got to the last step.
I needed to get my encrypted token by entering "fastboot oem get_identifier_token" to be able to submit it to HTC, and after they would send me an e-Mail with an .bin file that would let me unlock the bootloader to be able to flash my way through all this headache giving fucking piece of dog shit!
But since I can't back to the phone settings to select the bootloader activation box that would let me get my token... but nah.

Here, a full retrospective of my Apple products ownership.
iPhone SE – after Android, I was absolutely amazed by how fast it worked. No UI lags, camera works absolutely instantly no matter the light conditions, all the GPU-heavy games work butter smooth.
After camera and charging port failures on Xperia flagship and CPU literally melting through screen rendering it unusable on Meizu, it was enough to make me interested in Apple products.
When I was using Meizu, I actually got a twitching eye which was triggered by UI lags. After two months of using iPhone, I noticed that something was missing – my eye wasn't twitching anymore.
iPhone actually cured me.
MacBook 12 – a 900 grams laptop with passive-cooled mobile CPU running many Chrome tabs, heavy Webpack HMR build, VSCode and Slack just fine. Yes, you can't play games, but I don't even require it from a laptop this tiny.
Butterfly keyboard that internet hates so much actually increased my typing speed and comfort compared to MX Red mechanical keyboard, and ForceTouch trackpad made me forget about mouse. I learned how to disassemble the Butterfly keyboard if I ever need this but the keyboard never failed.
I use this laptop to this day and it still even smells like the day one, a beautiful smell of a new Apple product.
iPhone X – got it because of the camera, stayed for great battery life and amazing OLED display. I use telephoto lens exclusively and it made me lay off my Canon DSLR with Helios lens which stays on my bookshelf covered in dust to this day.
True black of OLED display which is undistinguishable from the screen bezel is stunning. To this day, battery surely works for one and a half days and I watch youtube really often.
I sometimes struggled to unlock iPhone SE with wet fingers, but with FaceID, as soon as I look at the screen the phone is unlocked. Works perfect every time, never had an issue with this.
Stainless steel body feels premium compared to aluminum. Stereo sound is a major selling point if you're like watching videos and playing games on your phone. Overall amazing product and a huge improvement over SE.
Apple Watch series 4 – really comfortable fit. Nice battery life, once I forgot about it for like ten days during lockdown and it was still working, even though on power reserve mode. Really reliable in terms of battery life and liquid protection. Very satisfying Taptic Engine crown clicks. I run every day and Apple watch always measure my heart rate correctly, and the running app is well designed and a pleasure to use. Overall a nice accessory to have if you use iPhone.
Powerbeats Pro – great sound and battery life. I switched from Shure SE215 which was great, but it had wires. I listen to a lot of music so the sound quality is important for me. When I was choosing earphones I visited a store where you can listen to them all. I listened through earphones like Noble Audio Kaiser Encore and JH Audio Layla, and of course $4000 Laylas sound better than $249 bluetooth earphones, but the difference in sound doesn't justify the difference in price to me.
Powerbeats pro is the Apple H1 chip true wireless earphones with largest driver of them all which makes them sound better than AirPods Pro – it's just physics. Bass in Powerbeats is amazing, which is also true for my Shures, but Powerbeats also win in clarity.
It connects seamlessly to both my MacBook and my iPhone, and everyone in voice chats can hear me really good.
Huge case is a major throwback compared to AirPods, but the battery life of earphones themselves is so great that I just leave the case at home and only carry earphones and it works for me.
Apple Link bracelet in space black – really better than I expected. Intricate detailing, literally the steel that Rolex uses, top-notch finishing and polishing – all that for just 450 dollars. I only used it for several days now, but it already feels like a really satisfying product.
Before all that I was using Linux. It took a year for elementaryos devs to fix wifi for my laptop. Ubuntu looks and feels ugly. Pop OS felt like garbage. Manjaro was also just that – garbage. KDE Plasma – I don't even want to talk about that. A monstrocity where you accidentally click a wrong switch in the settings and your system won't boot up again. Also, PulseAudio. Struggles with proprietary drivers and software updates.
Windows? I serviced a lot of Windows PCs through my career and it never, never worked as intended. I'm no dumbass, I always managed the rights correctly and never installed sketchy apps. My latest ryzen gaming build with a lot of ram also lags somehow even in Windows 10 UI.
Before I switched, I defended Linux.
My life was a lie.
I'm sorry to everyone who I offended based on their opinion on Linux.33 -
Today spent 20min in a senior android dev interview debating an ex backender CTO about the importance of final classes where he tried to pull out some sort of perfect answer from me about it. Ironically this is the same CTO who failed managing a previous android contractor who was supposed to rewrite old app and ended up with an even shittier new app in 6 months of time. Now they are insecure and are looking for a new contractor who will be micromanaged this time.
But hey I guess he knows the importance of final classes. Some CTO's need a reality check and at least some business training, because your perfectly written app is useless if it doesnt fulfill business needs.
Their app is based on heresdk and built around navigation. The biggest bottleneck is that it works shitty on low end devices so their competition solved this problem by using a whitelabel rooted tables with a custom ROM wher u have full control over hardware, permissions and battery management. However this startup thinks they can build a perfect navigation app which will work perfectly on all devices while at the same time while also relying on a poorly optimized navigation sdk. Poor initial strategy I'd say and they didnt learn from previous 2 failures, now they are searching for the next savior android contractor who will have to solely implement evrything. -
I feel like writing or telling people about the time I jumped from Windows 7 Ultimate and jumping to Windows 10. (I'm not against 10, but I'm never updating after what had happened to me)
It all starts when none of my games will play due to a possible issue with my graphics card. I look up "3D source game bug" and not many results pop up. I go on Microsoft's Qna areas and ask this question but to my surprise nothing they say would make sense. "Clean the pins of your graphics card, make sure you verify the games on Steam". I verified the games and they checked out as perfectly fine. I don't have access to my graphics card because this is a laptop, sadly not a tower.
Two months pass and my computer is already showing signs of stress, like it didn't want to live in a sense. It was three times slower than when I was on Windows 7 and it was unallocating areas of my main hard drive where I could make virtual hard drives.
Instantly I start looking up Linux distros and find Linux Mint. 17.3 was the current version at the time. I downloaded it and burned it onto a DVD-rom and rebooted my computer. I loaded into the disc and to my surprise it seemed almost like Windows 7 apart from the Linux part. I grab my external hard drive and partition it to hold the Linux distro and leave it plugged in incase Windows 10 does actually fail.
On December 19, a few months after Windows 10 had released. I start my laptop to try and continue my studies in video game development. But to my surprise, Windows 10 had finally crashed permanently. The screen flickered blue and black, and an error box saying Loginui.exe failed to start. I look at it for a solid minute as my computer had just committed suicide in a sense.
I reboot thinking it would fix the error but it didn't. I couldn't log in anymore.
I force shutdown the laptop and turn it back on putting it into safe mode.
To my surprise loginui.exe works and I sign in. I look at my desktop, the space wallpaper I always admired, the sound files, screen shots I had saved.
I go into file explorer and grab everything out of my default hard drive Windows was installed on. Nothing but 400gb got left behind and that was mainly garbage prototypes I had made and Windows itself. I formatted my external hard drive and placed everything on it. Escaping Windows 10 with around 100GB of useful data I looked at the final shutdown button I would look at.
I click it and try to boot into normal Windows 10. But it doesn't work. It flickers and the error pops up once more.
I force it to shutdown and insert the previous Linux Mint disc I made and format the default hard drive through Linux. I was done. 10 gave me a lot of shit. Java wouldn't work, my games has a functional UI but no screen popped up except a black abyss and it wouldn't even let me try to update my graphics card, apparently my AMD Radeon 5450 was up to date at the AMD Radeon 5000's.
I installed Linux Mint and thinking the games would actually play I open steam and Launch Half-Life 2 to check if Linux would be nicer to me than Windows 10 had been.
To my surprise the game ran. The scene from Highway 17 popped on screen and the UI was fully functional. But it was playing at 10-15fps rather than the usual 60-70fps. Keep look at my drivers and see my graphics card isn't in use. I do some research and it turns out I have a Hybrid Laptop.
Intel HD Graphics and an AMD Radeon 5450 and it was using the Intel and not the AMD. Months of testing and attempts of getting the games to work at high frame rates pass and the Damn thing still functions at a low terrible fps. Finally I give up. I ask my mom for a Windows 7 disc and she says we can't afford it. A few months pass and I finally get a Windows 7 installation disc through money I've saved up. Proudly I put it into my optical disc drive and install it to my main hard drive deleting Linux completely. I announced to all my friends my computer was back in working order and I install everything I needed, Steam, Skype, Blender, and Unity as well as all my games. I test Half-Life 2 and it's running exceptionally smoothly, I test Minecraft at max settings and it's working beautifully. The computer was functioning properly once again and my life as a developer started as I modeled things and blender, learned beginners C# and learned a lot of Batch. Today the computer still runs at a great speed and I warn others of what happened to me after I installed Windows 10 to my machine if they are thinking of switching from 7 or 8 on an older machine.
Truly the damage to my data cannot be undone. But the memory of the maintenance, work, tests, all are a memory of how Windows 10 ruined me and every night before the one year anniversary of Windows 10's release, I took out the battery of my laptop and unplugged it from the a.c. power, just so Windows 10 doesn't show it's DLLs, batch scripts, vbs scripts, anything on my computer. But now, after this has happened and I have recovered, I now only have a story to tell5 -
Why i got the message 'Input/Output Error" when mounting /dev/mmcblk0p2....
Nothing crashed till i just booted twice to enter different systems Android and MeeGo (via Ubiboot).And when i powered off my Android and tried to boot into MeeGo, it said "Boot OS/kernel selection failed! \n Please run a maintance boot"
I already ran a maintance boot...
And i entered Ubiboot's Telnet (low battery), found that /dev/mmcblk0p2 failed to mount with an error "Input/Output error", but i dd'd this partition (copy data into a file), everything was fine...
And after that, my phone turned into blank...
So can anybody tell me how to fix this? It's not like a hardware problem, i think there's something wrong with the data in the partition, like the header...3
