I have a problem with an IPC laptop, it's around 3 years old. 6 months ago had a new hard disk replaced due to clunking and data corruption - the Laptop only gets used say every 3 weeks and suddenly it has problems getting past the POST - I.e can't detect the H/D- I've checked in the bios when this tends to happen and there is no sign of the 20GB Hitachi Drive listed in there. If i power down the Laptop and fire it back up then it seems to pickup the drive and Windows will boot normally. This does only happen when it's been off for a while and once it's warmed up you can shut it down and it will fire back up ok.
I was wondering if this could be CMOS battery related, or possibly a Mainboard IDE problem.
~The drive is fine.
Thanks for any help.
