Search - "dead battery"
Mac: Suddenly turns off
Me: Fuck my code..F***
Mac: No response at all
Me: reset SMC etc etc
Mac: I am dead (no battery detection, dies after 10 min on power adaptor)
Me: Skips a heart beat..(Git, oh yea git)
**Takes Mac to store, After diagnosis**
Apple Freaking Genius (AG): Your Mac has a mother board problem it needs to be replaced.
Me: Hmm what is the problem exactly??
AG: Issues in logic board and some other components.
Me: How much?
AG: Out of warranty so $$$ (60% of original amount)
Me: (wtf?) Really
AG: It's entire motherboard replacement .. bla bla

Builds a raspberry pi backup laptop with 3d printed body..Ubuntu.. you know can't live without a computer
I once brought my Kali Linux laptop to school. (Because normal had dead battery, waiting for shipping)
MFW someone from the IT department is called in to fix teachers projector and he sees I still have the default dragon wallpaper on it.
MFW when recognises it it's Kali.
MFW he calls the police and my laptop gets taken away because 'its dangerous' and I get questioned in school.
The police came back a week later to check my laptop again. 'uhh we gotta check the logs'.
IF I WANTED IT TO BE DANGEROUS YOU'D BE FIXING A LOT MORE THAN JUST THE FUCKING PROJECTOR!
Also, wuddup devrant!13
Long rant ahead. Should take about 2-3 minutes to read. So feel free to refill your cup of coffee and take a seat :)
It turns out that the battery in my new Nexus 6P is almost dead. Well not that I didn't expect that, the seller even explicitly put that in the product page. But it got me thinking.. why? Lithium batteries are often good for some 10k charges, meaning that they could last almost 30 years when charged every day! They'd outlive an entire generation of people!
Then I took a look at the USB-C wall charger that Huawei delivered with this thing. A 5V 3A brick. When I saw that, I immediately realized.. aah, that's why this battery crapped out after a mere 2 years.
See, while batteries are often advertised as capable of several amps (like 7A with my LiitoKala 18650 batteries that I often use in projects), that's only the current that they can safely take or deliver without blowing up. The manufacturer doesn't make this current rating with longevity in mind. It's the absolute maximum in current that a given battery can safely handle.
The longevity on the other hand directly depends on the demand that's placed on the battery. 500mA which is standard USB 2.0 rating or 1A which is standard USB 3.0 rating, no sweat. The battery will live for at least a decade of daily charges and discharges like that no problem.
But when you start shoving 3A continuous into a battery, that's when it will suffer. Imagine that your current workload is 500mA and suddenly you get shoved 6 times that work upon you. How long would you last?
Oh and not only the current is a problem, I suspect that it also overvolts the battery to maintain a constant current all the way till the end. When I charged my lithium cells with my lab bench power supply, the battery would only take a few milliamps when it got close to the supply voltage. Quick bit of knowledge: lithium cells are charged at constant current first, then when the current drops below that, it continues at constant voltage - usually 4.2 or 4.35V depending on the battery. So you'd set your lab bench power supply at 4.2V 500mA. But in that constant voltage mode, as the battery's voltage and the supply's voltage equalize, the current drops because the voltage difference becomes lower. Remember, voltage is what causes current to flow. Overvolting at the supply to stay in constant current mode all the way till the end speeds this process up but can be dangerous and requires constant monitoring of the battery voltage.
So, why does Huawei and a bunch of other manufacturers make these 3A power chargers? Well first it's because consumer demands ever more, regardless of the fact that they can just charge at 500mA for the night (8h of sleep) and charge a 4000mAh battery from 0 to 100% no problem. Secondly it's because sometimes you need that little bit of extra juice fast, like when you forgot to plug the damn thing in and you've got only 30 minutes in the morning to pour some charge into it.
But people use those damn fucking things even when they go to bed, making that 3A torture a fucking standard process!! And then they complain that their batteries go to shit?!
Hopefully this now made you realize that the fast charger shouldn't be used as a regular charger ^^30
The moment i started Android Porting.
The tons of messages i got on XDA from random people.
Oh fucking hell
But one message was like WTF ?
Not exactly the message but it has the same point.
Hey Bro, I installer your room and it work but when i turned my phone of it didnt turn back on. The small buttn on side doesnt work to turn it on.
Then he posted the same message to thread since i dont respond to PMs.
Some user helped him and what was the issue ?
HIS FUCKING PHONE BATTERY WAS DEAD
He just had to charge it. FFS6
Four engineers get in a car. The car won't start.
The mechanical engineer says:
It's a broken starter.
The electrician's engineer says:
The battery is dead.
The chemical engineer says:
There are impurities in the gas.
The software engineer says:
Guys, try getting out of the the car then back in!1
I fried my laptop's lithium-ion battery by overheating it too much when gaming for 1.5 years now. Was only getting 20 minutes on a charge. Bought a replacement battery to install.
My laptop is full-body aluminum, and when removing the difficult-to-remove backplate, I sliced my thumb deeply on the razor-sharp internal edge of the backplate.
Hurt like hell. Took a while to get the bleeding to stop. I had to finish what I started, so I swore I'll be careful the rest of the time.
Yet somehow, my hand eventually slipped and I ended up slicing my OTHER thumb, on the exact same component! And the gash was even deeper and hurt even more! And took 3x as long to stop bleeding! I lost so much blood... 😫
Moral of the story: Be careful when dealing with full-body aluminum laptops. They're fucking evil and dangerous. Also, don't let your laptop reach temps above 82-85 degrees Celsius.
Thankfully, no tetanus from any of this. 😓25
Friend of mine killed his MacBook with some Softdrink.
Just poured it all over his poor a1502.
He let it dry for a few days, it starts to work again.
Except the battery.
Goes on Amazon and buys a new battery.
New battery doesn't work either and so he tells me about it and I as stupid as I am couldn't resist the temptation to finally work on a MacBook like my "hero" Lois Rossmann does.
So turns out the board is good.
Cleaned it up and basically nothing happened to it.
So what's the deal with "los batlerias"?
The first got hit by liquid, the second had a broken connection to a cell.
That could have happened through my friend, installing it without testing it first, or at the seller, so it being a DOA battery.
Now away from the stupidity of my friend and the situation to the actual source for this rant.
Once something happens to a modern Managed battery, the Battery Management System (BMS) disconnects the voltage from the system and goes into an error state, staying there and not powering anything ever again.
For noobs, it's dead. Buy a new one.
But It can be reset, depending you know how to, and which passwords were set at the factory.
Yes, the common Texas instruments BQ20Zxx chips have default passwords, and apple seems to leav them at default.
The Usb to SMBus adaptors arrived a few days ago and I went to prod the BMS.
There is a very nice available for Windows called BE2works, that I used the demo of to go in and figure out stuff. The full version supports password cracking, the demo not.
After some time figuring out how Smart Battery Systems (SBS) "API" works, I got to actually enter the passwords into the battery to try get into manufacturer and full access mode.
Just to realise, they don't unlock the BMS.
So, to conclude, my friend bought a "new" battery that was most likely cut out of a used / dead macbook, which reports 3000mah as fully charged instead of the 6xxx mah that it should have, with 0 cycles and 0hours used.
And non default access.
This screams after those motherfuckers scaming the shit out of people on Amazon, with refurb, reset, and locked fucken batteries.
I could kill those people right now.
Last but not least,
My friend theoretically can't send it back because I opened the battery to fix the broken connection.
Though maybe, it'll get send back anyway, with some suprise in the package.9
Disclaimer: I have a strong hate towards apple for multiple reasons and this will only be temporary. (thank God for that)
My oneplus one is battery dead and the power button quit as well. Repair costs would be as expensive as buying a new phone (200-300 price range) so searching for a new one.
But, I need a temporary phone in the mean time.
A phone with googled-android is absolutely a no-go. I used to do that sometimes but those were wrong decisions.
So, for the sake of trying, I'm going for a second hand iPhone.
Will be testing how it works for me (never been able to form an opinion on it since iOS 4.2 (iPod touch)) and will also be searching my ass off for a smartphone which supports lineage/rooting (TIPS BETWEEN ABOVES PRICE RANGE ARE VERY WELCOME) because I'm fucking hell not planning on using that (the iPhone) fucker any longer than a month.
Even if I love it over android (highly doubt that), I won't continue using it for very specific reasons.
Wish me luck 😅16
On the top of a mountain, while skiing, -6 °C, no gloves, on my phone.
I use a live wallpaper I made with Processing and it uses gps location and forecast datas to change the background image according to the environment and climate. It sucks and drains battery like a bitch, and as soon as I got the top of the mountain it fucked up everything, home screen froze and camera wouldn't open.
So guess what, it was debug time. Hands dead cold and APDE with no autocomplete on a smartphone keyboard. The agony.
My gf yelled at me and after 10 minutes I switched to a static wallpaper, uninstalled that one and never touched it again since then2
This is my little "setup".
Have a gaming laptop, too. Battery is barely dead but meeh. Maybe I'll try installing ACK... ehm... ARSCH linux on that 🤔
Some specs as new screenshot in a comment below ☺20
Shit morning, I work in tech, so I guess it is related haha.
First, I wake up and it is cold. Like -12 degrees Fahrenheit. With wind-chill, feels like -29 according to Google. Then, while getting ready for work, my only belt breaks. Not a little, but literally splits in half! Fucking sucks, as my pants keep partially falling down and my shirt keeps untucking.
I go out in this cold that could kill a polar bear, go to start my car. Can you fucking guess? Dead fucking battery. Fuck! Now I am super late to work.
Make it to work, and guess what? My manager just promised 100% completion by Friday, and we are weeks behind! Fucking sucks... I think my coworker snapped, as he keeps hyperventilating at his desk for no reason. Oh and our best coder just quit...
Waiting to either wreck my car or find out my dog is dead when I get home...4
I’m pretty terrible at soldiering and small electronics in general, but I’m kind of okay with how this turned out.
That helmet is my sister-in-law’s, she drives a polaris slingshot. (It’s technically a motorcycle here in the US because it has three wheels.) and she hooked up some EL wire to her helmet and the larger black rectangle in the picture is what the battery pack looked like before. (It takes two AA batteries.) and doesn’t have anyway to recharge them natively.
I did some research and found a neat little charging board (TP4056) and got her a small single cell li-ion battery for it. Now it’s not only less than half the length of the original, but it has a rechargeable battery and a charging circuit built in. The battery is 500mAh and lasts about 65-70mins on a charge. Personally, I feel like that’s not a good enough battery life on a charge, but my sis-in-law says that her and her slingshot friends usually only run with the EL lights on for 30 minute stretches at time so they should be able to get two to three uses before needing a recharge. Which btw, only takes about 35-40 minutes from completely dead.
The box looks like shit cause I literally hacked away at the original casing with a pocket knife and then crammed all the pieces back in and hot-glued the casing together. But I took measurements of the final-ish design and will try to find a small electronics box that will be able to house everything internally. (L: 1-3/4” W: 1-1/4” H: 1-1/4”)7
My mum just came to me asking me why the mouse is not working ...like I'm GOD of electronics :( (I'm just a simple dev) I simply though that the battery is dead because it's old. Soooooo.....
I showed her how to open it and how to change the battery. After 5 min she came back with a new battery and the same mouse asking me to fix it for her....
In my mind I literally snapped my brain was bleeding and exploding at the same time.
I just cringed a fake smile and changed the battery in front of her very slowly. I sure she won't remember how to do it next time.
At the end of the story I can't talk back or be angry to my parents I have to much respect for them. They though me everything from how to poop, speak, dress, eat and so on.
Be kind to your parents.5
A friend of mine called yesterday with a HUUGEEE FUCKIN PROBLEM!! His work on his thesis (to finish his course) is inside his laptop, and "the laptop is stuck at 91% of updates" since.. Like.. 5h. "It won't turn on again! I'm dead!! Pleeeaase heeelp"
I went to his home, sit at the front of his PC, took off the battery and the power cable, shut it off and then turned it on again.
"OH! MY! GOD!!!" "You truly are a fuckin God with this!!"
"Dude. You're just stupid."
Ps. I'm still his friend, I guess4
The amount of battery on my phone is inversely proportional to how hard I haven't been working throughout the day. I'll tell you more about this problem once my phone's dead
I have a cheap crappy drone and while not using it I hang it on the smoke detector. Neither the drone or the smoke alarm have batteries.
I glance up and see a light flashing, freak out, shoot the drone...lights still flashing and I realize it's the smoke detector. Fuck that, there's no batteries. I shoot the smoke alarm and it explodes...battery lands at my feet still intact...
...the alarm is dead, the drone is crying, the toaster is laughing and I can't figure out why the fuck I shot my drone and smoke detector but the toaster doesn't phase me.
(Some of this is actually true)3
It might seem stupid but lets do a thread with our watched. I wans never interested about those little accesories until i got mine a few months ago and now i wear it everywhere 😃
True gamechanger when talking about exams and dead battery situations as it has some machanism of charging itself without using batteries and it gloes in the dark 😏16
The world is so stupid... An app called Die With Me works only under 5% battery and lets you chat anonymously... when the connection is lost its said "*Name* Is dead"
Really fucking stupid but worth a try... Why did i buy this ag1
A Rant that took my attention on MacRhumors forum.
I pre-calculated projected actual overall cost of owning my i5/5/256 Haswell Air, which I got for $1500.
After calculations, this machine would cost me about $3000 for 3 years of use.
(Apple Care, MS Office Business, Parallels, Thunderbolt adapter to HDMI, Case... and so on).
Yea... A lot of people think it's all about the laptop with Apple. nah... not at all. There's a reason Apple is gradually dropping the price of their laptops.
They are slowly moving to a razor and blade business model... which basically is exactly what it sounds like - you buy the razor which isn't too expensive, but you've got no choice but to buy expensive additional blades.
I doubt Apple is making much money from laptop sales alone... well definitely not as much as they were making 5 years or so ago (remember the original air was about $1800 for base model, and if i remember correctly - $1000 additional dollars to upgrade to 64GB SSD from the base HDD.
Yes, ONE THOUSAND DOLLARS FOR 64GB SSD!
Well, anyways, the point is that Apple no longer makes them BIG bucks from the laptop alone, but they still make good profits from upgrades. $300 to go to 512GB SSD from 256, $100 for 4GB extra ram, and $150 for a small bump in processor. They make good profits from these as well.
But that's not where they make mo money. It's once you buy the Macbook, they've got you trapped in their walled garden for life. Every single apple accessory is ridiculously overpriced (compared to market standards of similar-same products).
And Apple makes their own cables and ports. So you have to buy exclusively for Apple products. Every now and then they will change even their own ports and cables, so you have to buy more.
Software is exclusive. You have no choice but to buy what apple offers... or run windows/linux on your Mac.
This is a douche level move comparable to say Mircrosoft kept changing the usb port every 2-3 years, and have exclusive rights to sell the devices that plug in.
No, instead, Intel-Microsoft and them guys make ports and cables as universal as possible.
Can you imagine if USB3.0 was thinner and not backwards compatible with usb2.0 devices?
Well, if it belonged to Apple that's how it would be.
This is why I held out so long before buying an apple laptop. Sure, I had the ipod classic, ipod touch, and more recently iPad Retina... but never a laptop.
I was always against apple.
But I factored in the pros and cons, and I realized I needed to go OS X. I've been fudged by one virus or another during my years of Windows usage. Trojans, spywares. meh.
I needed a top-notch device that I can carry with me around the world and use for any task which is work related. I figured $3000 was a fair price to pay for it.
No, not $1500... but $3000. Also I 'm dead happy I don't have to worry about heat issues anymore. This is a masterpiece. $3000 for 3 years equals $1000 a year, fair price to pay for security, comfort, and most importantly - reliability. (of course awesome battery is superawesome).
Okay I'm going to stop ranting. I just wish people factored in additional costs from owning an a mac. Expenses don't end when you bring the machine home.
I'm not even going to mention how they utilize technology-push to get you to buy a Thunderbolt display, or now with the new Air - to get a time capsule (AC compatible).
It's all about the blades, with Apple. And once you go Mac, you likely won't go back... hence all the student discounts and benefits. They're baiting you to be a Mac user for life!
Apple Marketing is the ultimate.
Snapchat is by far the worst app ever developed. I like the concept but the actual development of the app is fucking garbage. It hurts my head that they haven't given a fuck about usability, optimisation or anything for that matter considering its one of the top social media platforms. It disgusts me, though Instagram has completely ripped off Snapchat in so many ways; they've done a hell of a better job at it and if people weren't so tired to SC I'm sure it would be dead by now.
Slow UI, slow gestures, probably the highest amount of bugs and crashes, shit camera because it thinks it can do a better job than the native API at rendering, painfully slow upload, stupid "featured" stories that you cannot get rid off and slow the fuck out of the app, battery drain even worse than FB, oh and not to forget that once you accidentally enable your location it's impossible to switch it off, the best you can do is hide it from everyone. I can probably go on and on with the endless issues this shit has.5
Pretty sure my laptop's battery is dead...
Works fine when plugged in but dies without power cord...
So much beer wasted
At least I'm getting a higher capacity one, and the previous one lasted 3,5 years, so that's not too bad...2
Just replaced my dead battery on my Dell XPS 13 2013 with a brand new one. One whole month I was unable to unplug without a shutdown, not to mention that I couldn't boot it easy due to the dead battery... finally... justice.3
Visual Studio Code + Mac = not lightweight, really not that good performance
I mean the battery is burning. Literally, i plug my mac out and after a hour the battery is dead10
TLDR; windows sucks donkey balls
Sometime ago I started to get battery issues on my laptop using windows. Even with 100% charge it would soon display 0% when unplugged.
A few months back I switched to linux on my laptop and on my desk station. And to my surprise, battery issues dissapeared while using linux (manjaro i3). Anybody had that same problem?
Anyway I dual boot win 10 and linux just in case I'd need windows, and this week I noticed my root parition didn't have any space left.
For the next few hours I'm in a car so I thought hey great time to reinstall linux with a bigger root partition. I already had reinstalled windows, and with all the bloat removed, I could shrink my windows partition to make more space for linux.
Now all I need to do is prepare a usb stick with the manjaro iso. I could do that in linux, but since reinstalling windows killed my grub bootloader I couldn't boot up manjaro.
Right, so in windows I go and want to create this bootable EFI usb stick from the manjaro iso. Now the battery issue kicks in again, stating 0%. But with luck, the usb creation finished without my machine dying. Now I just need to restart my laptop and boot from the usb and .... Crap. my Laptop doesn't boot up anymore
Now i need to wait for a plug to be able to power it up again. Once I boot from the usb I'm sure I could use the laptop some more hours until the battery is actually dead. Fuck windows5
why the fuck can't android phones have a voltage indicator when charging, I want to motherfucking see if my phone is dead or just the battery is retarded14
Fuck me. I was installing arch after giving up on manjaro not working, and after fighting to get it connected to the wifi, I forgot to plug it in and it died 30 minutes or so into pacstrap.
Goddamned idiot, that's what I fucking am.
Anyone had any luck installing Linux as the boot OS on a Macbook?
I have an old Macbook Pro with a dead battery that I'd like to tinker with, and while it looks possible from what I've found online, I'm curious if anyone here's had any luck.7
Remembering of when I first learnt about the importance of version control.
There I was, working in Visual Studio, laptop unplugged; the laptop suddenly shuts down - battery dead. Not too worried, might just have to rewrite a few lines I had not saved. Restart the machine, open VS, the file I was working on now contains strange characters - totally damaged.
Google for help, find a question on stackoverflow with the same issue (comforting moment). The answer I get:
"First question, why wasn't your code on source control?"4
This month is a nightmare,
1. Laptop battery dead
2. Laptop hinge broke
3. NIC Card dead(no idea but maybe because of the hinge )
4. Power Jack got fucked
5. Laptop Fan kinda dead(sometimes work sometimes don't maybe due to power issue)
6. Mobile's charger wire fucked
My laptop battery just died, this morning it was working fine, i left it in standby and when i got back it was turned off, now it shows 0% not charging.
The laptop is less than 2 years old, i think windows killed the battery by letting it fully discharge (well, it's my fault after all), still now i've got to get a new one (╯°□°）╯︵ ┻━┻.
Ok so i have two laptops, one has One slot with ddr3 4gb ram and is way too slow for school, the other one is 5years old but fast as hell but has a dead battery. Should i buy a 8gb bank or a new battery. Providing the price is roughly the same.. ??5
So I have been using my HP laptop(r007tx) for over two years and a half now. Here are it's top 'features'
1. A dead pixel on the screen. Slowly it started to grow every time I close and open the lap and eventually it grew to a horizontal line across the screen. Luckily it was under warranty.
2. Volume is very low. Can't be fixed.
3. Broken hinges. Never had it faced any impact.
4. WiFi adapter stopped working after an year. Bought an external adapter.
5. Monitor frame started to come off.
6. Battery is shit. Explained it a bit detail here.
7. DVD player doesn't work.
Most of the problems came just after one year. If you are thinking to buy HP laptop do pay for extended warranty.
But still successfully running it because of the software that every dev has developed.
Surface Pro shows battery status at 0% - Not Charging. Turns off as soon as power is removed. Looks like battery is dead. Anybody have any troubleshooting tips?5
Hey guys, my apple watch series 2 got broken recently. It doesn’t charge at all. It’s like electricity what’s that?
So I did all troubleshooting you can think of and all the ones on the web. Still no go.
Although some ppl reported that after a week or so their watches started charging again and didn’t have the problem anymore(which points out to some software error and once battery completely drained it kinda reset itself?). Anyway my battery is dead like nothing ever comes up on the screen anymore but still doesn’t charge.
I wanted to ask if anyone here had such problem and found a solution to it maybe?3
