|Do you see a line while booting like that mentioned in the last part of response 4 ?|
I looked at the User Manual available here:
models sold before 2006
VGC-V2M (main support page; on the Sony Europe web site)
but it has no info about a battery or removing passwords.
A similar User Guide for a VGC-V3M mentions passwords and that it has a backup battery on the mboard but there is no info in it about how to remove the battery.
I searched for a service manual for VGC-V2M - if there is one I found nothing obvious in the many "hits" I looked at.
I did find at this link:
a post in the thread that says:
"Hi If anyone is interested i have guide for disassembling the VGC-V2M. I realise this thread covers a different model but the process would be similar.
Disassemble A Sony Vaio VGC-V2M Desktop Computer (http://www.digitalconversions.ie/blog/?page_id=3) "
I tried using the
line in a browser, but it no longer works.
However, his web site link works
and you could try contacting him
See the info in response 4 about setting the Date and Time .
Otherwise, take it to a local place that is authorized to work on Sony computers and have them open it up and remove the battery, replace it.
The battery usually lasts 5 years or so. It's often a common CR2032 one.
Your model was first made before 2006. It would be a good idea to replace it if you intend on using the VGC-V2M for a while
