Hello! I made little scraches under cmos battery by mistake and after i put back cmos battery Toshiba Satellite laptop doesn’t start. There is no power ( its connected to power ), doesn’t show battery or no other light. Totally no signs of life. I want to ask the problem is on motherboard or another thing? How can i check and proceed? Please help me, thanks! Update (08/09/2021) Here: https://ibb.co/Fn52vm8
If the laptop worked fine BEFORE you scratched (?) the CMOS battery then just replace the battery. The CMOS battery is how the laptop keeps all the settings for the BIOS/UEFI - how the computer knows what to do. Let us know how it goes. These “CR2032” batteries are cheap and can be purchased just about anywhere.
Can you provide photos of the affected area?
