Asus X555U battery not detected after screen replacement

[seanmyers1992]

Hello. I have recently acquired a laptop in which the battery is not detected. The laptop will only work when plugged into mains - it also starts up automatically when plugged in (i.e. power button not pressed). If the power button is pressed when it is started up it will restart, if using the software to shut down the laptop it will stay off. Now as I acquired the laptop I don't know exactly what has happened previously, but apparently the screen was damaged and then therefore replaced. From that point forward the battery was not working.
Any ideas or suggestions about the reason for this would be greatly appreciated

Sound like when they replace the screen they forgot to plug in something or broke something on the system board.

These were my thoughts too, first job will be to open it up I think!

So having opened up the laptop yesterday I tried a few different things:

Taking the battery out and inspecting - seems to look okay
Tested the battery with a multimeta - it read at about 2.5v - not the 7 or so it was supposed to be
Took the laptop apart - inspected the motherboard - nothing obvious going on there - would a fuse blown normally be visible?
Re-attached everything and put the laptop back together without the battery - booted laptop and it seems to be exactly the same with or without the battery.
Inserted the battery - no change.

Tried to look for the CMOS battery but it did not appear to be on the motherboard, I've read some forums suggesting this could be the cause - has anyone else had this experience?

I also uninstalled drivers for the battery and AC adapter - once windows booted up and the battery indicator said attached but not charging.

I've also tried re-installing windows 10 from fresh wiping the hard drive - didn't solve the issue.
I have seen some say that windows 10 sometimes causes issues with batteries so I may well try installing windows 7.

Does anyone have any further suggestions? I'm starting to feel like this is going to be an impossible task!

Hi,

I'm not a expert but I can share what happened to me. Once I put a bad battery charger and it blew the fuse, protecting my mother board against short-circuit. I disassembled the pc and a friend used a multimeter to find the dead component, where the electricity stopped. Once the fuse was removed my battery started was getting charged as before.

My advice is to search the fuse or maybe in your case the connector from you battery to your laptop. Follow the electric flow and see where it stops.

Best of luck
