Does anybody know if it possible to power a laptop directly from the mains adapter without having the battery fitted? I have briefly tried this but nothing happens when the on button is pushed.
The reason for my query is that I suspect the laptop's battery is no longer useable and may be preventing the laptop from starting properly. The voltage across the battery terminals is approximately 0.1V. It is a Sony laptop, serial number PCG-FX301/PCG-962C.
After pressing the on button the POST usually completes without error but everything shuts down again a few second later before fully starting Windows.
Best regards,
