"primary hard disc not found" "no bootable devices" message on cold start up , I have updated the bios to (A16) and what ever drivers i could find on the dell site, new main battery, when i get this message on cold boot I hit F2 and change the Boot POST:to min/auto/thorough and or change the PXE BIS Policy: to reset/accept and then save changes and it will boot up fine, now if i turn it off for about 1/2 to 1 hour its OK but leave it off for a couple of hours or over night this message comes back and back into the bios I go, also i noticed when i hit F12 for Dell Diag it said No diagnostic utility Partition found and I don't have the Dell "Drivers and Utilities" CD to boot off of -
any help
