Resting by C-MOS battery

Resting by C-MOS battery 

All the cmos and bios setting is saved in the bios chip which was attached on the motherboard. The main work of cmos battery is giving a continuous power supply to the bios chip to save all the settings. If you unplug or remove the battery for above 5 sec, the bios setting will be reset.

Step 1 – Unplug all the power supply which connected to the laptop like “Laptop Battery” or “Power Adaptor”.

Step 2 – Disassemble your laptop and find the CMOS battery which was attached to the laptop’s motherboard. Watch your laptop disassembly video to know where your laptop’s cmos battery was located, sometimes it was on behind the case of ram.

Note – If you don’t know how to disassemble your laptop then watch a disassemble video of your laptop on YouTube or some helping website.

Step 3 – Disconnect the CMOS battery.

After finding the battery, just disconnect it or remove the battery for 5 sec.

Step 4 – Short the CMOS battery connector by the use of metal wire because in some of motherboard manufacturers backup the power to the Bios Chipset by using of some capacitor that’s why we short them to remove the remains power supply.

Step 5 – Reinstall the cmos battery and assemble back your laptop and that’s it. Power up your computer and the bios got reset.
