HP Notebook - 15-dw0103nl
Microsoft Windows 10 (64-bit)

Hello, since I chenged the battery and also updated Bios my PC does not turn on without external power connected.

Once pc is on I can disconnect the power and pc stays on for hours just with battery.

If I turn off the pc and then turn on within 5-10 minutes then it ok and it starts up.

If I wait longer ( let us say more than 10 minutes )  it does not power up unless external power is connected.

When I connect the power cable and switch the Pc on  I also get CMOS error , saying "Cmos checksum is invalid.Cmos will be reset to default config  and "Cmos reset (502) " .

After system reboots and pc starts working.

I think my notebook does not have proper CMOS Battery , which I could not find inside.

Thanks
