I had a 502 CMOS Error but after updating bios and uninstalling and reinstalling battery drivers the error doesn't show anymore.
But right now my laptop doesn't work without the ac adapter and it would shutdown as soon as I remove the adapter.
I tried to look for the cmos battery but I couldn't find it so I hope I can reset it or replace it can someone help!
Also I would like to ask where can I get a replacement for the main battery ht03Xl battery.
