Hi @ericz1025 ,

@acervasio  was talking about the CMOS battery not the main battery.

Here’s a link to a [https://www.youtube.com/watch?v=SN5Ag73Yd0g|video] that shows how to dis-assemble the laptop.

Here’s an image taken from the video that shows where the CMOS battery is and what it looks like.

After dis-assembling the laptop to a point where you can get to the CMOS battery (ensure that the main battery is also disconnected), disconnect the CMOS battery from the motherboard and then press and hold the Power button for 30 seconds to ensure that all residual power is drained from the motherboard and that the BIOS will be reset to its’ default settings.

Reconnect the CMOS battery and then re-assemble the laptop and check if the laptop now turns on.

If it still won’t start after this you may have a motherboard problem
