Default Sony laptop

Does anybody know if it possible to power a laptop directly from the mains adapter without the battery fitted?

The reason that I want to do this is that I suspect the laptop's battery is no longer useable and may be preventing it from starting properly. The voltage across the battery terminals is approximately 0.1V and the mains adapter output is approximately 19V DC. 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 before fully starting Windows.

Best regards,

You can remove the battery and have the unit plugged in. It will function just fine.

Thanks for the responses and my apologies for not responding before now.

Unfortunately nothing happens at all when the on button is pushed without the battery being fitted. Does this possibly mean that even though the battery may be defunct there is also a further fault that will not be remedied by replacing the battery.

Best regrads,
