I received a new display and battery for my iPhone 8plus from the iFixit store and installed both yesterday.
I am really happy about the display but I do have an issue with the battery:
I am unable to calibrate it, because after recharging it to 100% and letting it drain, the phone turned itself off at 50%.
I connected it back on charge and it showed 50% battery.
I tried again, and again at 50% the phone turned off, but this time restart it showed a 14% battery charge, although usage shows 50%

Don't really know how to make it work.

Screenshot1: first attempt: Phone turned itself off at 50%

Screenshot2: second attempt: turned itself off at 50%, then on restart shows 11% battery

The screen has been broken for a while now and my original battery was kind of wearing off so I decided to change both.

No drops and then battery doesn’t get specifically hot (normally when recharging)

Was a pretty standard swap, I suppose

I've had this thing forever and out of nowhere it would turn off after turning on for 10 seconds. It was booting into windows XP perfectly fine and then the issue would return. Online is no help just saying to apply pressure on a part near the power button for the duration you want to use it, I'm looking for a long lasting solution. Others have the same issue so it seems to be a design flaw. It may help that the pcb for the power buttons is separate from the main mobo.

The power button pcb on it's own

Main mobo without the button pcb

The pcb connected

@uchetil I can solder, the thing is I'm not sure what exact chip I need to re-solder. I remember this video shows where to apply pressure when powering on. Also I remember once getting it to stay on longer than 10 seconds only turning off when I manually shut it off so I could figure out which one I held down. https://www.youtube.com/watch?v=ILLvioWt...

I found an old Dell Inspiron 1420 and have been repairing it slowly over the last month or two. Recently I purchased this replacement charger for it as the laptop wouldn’t charge on my existing one designed for an HP laptop. With this new charger the “non-genuine adapter” message goes away and the computer reports it’s trying to charge the battery but it appears to remain uncharged no mater how long it’s plugged in. The bios says it is unable to communicate with the battery. The battery light on the laptop will blink orange forever when the laptop is plugged in on the new charger. I’m unsure what this means but my best guess is given the laptops age the battery is bad and will need to be replaced, but I wanted to double check before I order a new battery.

Hi,

I had stick drift that was unbearable recently, nothing could get it to stop so I decided to open up the controller and clean the potentiometers myself. Once I got that done and I even replaced the white thing inside the potentiometer with one from an old PS4 controller, I’m stuck with the right stick always going up. I’m not sure what I did wrong. I definitely didn’t break the green thing that latches onto the joystick since I barely moved it and I cleaned it pretty well. What could be the cause of this issue?

When i turn on my pc orange light blinks,I changed the ram,hdd but nothing happened.

Hi ,

I am thinking to use a Coollaboratory Liquid Ultra ( http://www.coollaboratory.com/en/product... ) but as per instruction manual it corrodes the aluminum and its recommended only for copper heat sink.

Thanks for your help.

So I decided to update to my HP 8440p elitebook and thought I could do it just like any other software, I had no idea.

I downloaded the installation from the official website and opened it and hit next next install like an idiot. The laptop turned off, I turned it on but nothing shows up on the monitor, just a black screen.

I did notice that the caps lock turns off and on which doesn't happen normally.

I've tried to hook up the laptop to an external monitor but still nothing just a black screen.

I would appreciate some help, thanks!
