what battery do i need

allan mccauley - Antwort

This is a CR2032 battery

Hyperion - Antwort

The receptacle that the battery goes into is loose and not making contact on the (+) terminal. This is a shoddy design. You can test it by pressing the receptacle down and powering the laptop. Works fine. You cannot solder the terminal for fear of upsetting the motherboard. Any solutions.

Until I find one, I continue to press F1, go to Control Panel and set the time and date every time I power on the laptop.
