Hi, I have a 4yrs old ASUS X456UV and as the title says one day I opened the case because I had been getting annoying black screens at boot that I couldn't fix and I found the weirdest tiny bump on my battery.
It's touching the inside of the case, which has changed color form silvery to bronze all around that point of contact in a 2cm radius and burnt black in the middle. So clearly there has been some electrical exchange between the battery and the case.
The battery itself has been slowly dying and is now basically useless weight since I can't unplug my laptop for even 5seconds.
I then decided to remove that battery completely and use the PC plugged, but I realized that there is probably no CMOS battery and my computer was using the main one for the BIOS as this hapoens with the battery removed :
1.When I turn off&unplug my computer the BIOS clock stops and restarts when I turn it on.
2.When I try to log in after it was unplugged with my current password it says there is no network and to use the old one.
3.Sometimes touchpad or keyboard don't work at boot, works when restarting.
4.BIOS does NOT detect 8 of the 12gb RAM ( it only detects the 4gb integrated one). I tried 2 different RAMs to make sure, and CPU-Z detects both. I'm not sure if that appeared when I removed the battery or before. Removing the 8gb RAM on top of the battery also prevents the black screen at boot somewhat.
5.Maybe not related- Computer turns on instantly when plugged in, without any input from me.
6.Finally, I can't find anything resembling a CMOS battery on the motherboard at all (I haven't looked everywhere but it would require completely removing the mobo which I'm not keen to do)
I am puzzled as to how that bump appeared, I never let my laptop fall, I do carry it around a bit but I have a protective sleeve and I'm careful.
And more importantly, what should I do now? Do you guys agree that the main battery was holding the BIOS info and remvoving it messed up stuff? Is it worth buying a new one or do you think my issues come from elsewhere?
I would really appreciate any help, I can't find similar issues on the internet and it's quite crippling.
