How to replace CMOS battery in SD32G2 shuttle barebone pc

[Guest]

I have SD322 shuttle barebone PC, it some times boot very nicely but if switch off then it will not switch ON and will give message as cannot find harddisk. May be after 6 hours it may start fine. Can anyone tell me what is problem. I suspect CMOS battery? How to replace & how to find exact type.
Please advice

That would typically mean the hard drive is failing not a bad CMOS battery.

Years ago (15) this may be the case - but no longer are we selecting tracks, cylinders, heads. Agreed with snipergod87. Very likely your drive is failing. BACK UP YOUR DATA pronto.
