Actually, I wouldn't call the BIOS clock being 5 seconds off much to worry about (with regards to the battery). They're not that particularly accurate, to begin with, on a par with a cheap wristwatch. However, if your battery is a few years old, you may as well replace it now that you're in the mood to do so. They do have a finite lifespan. If the BIOS voltage monitors say the voltages are fine, they probably are. Though they're not always super accurate, either. Software that lets you read these values when the OS is running needs to modify them with correction factors. Since you talk about many file system errors, and difficulty booting, I'm inclined to point the finger at the main power supply. If it's not up to the task of powering everything, or is randomly glitching, that could cause all sorts of instabilities. Though, as you're taking things apart. It may well be a good idea to unplug everything, and reconnect, just to exercise the connections (cars, RAM, cables, etc). Cards have a habit of walking out due to thermal changes, or mechanical stress when moving a flimsy case around. Clean any exposed slots (e.g. unused PCIe slots). I just did this simple search, and there's even videos of how to change the battery, right at the top. Though I don't think much of one person's crude "cut through the cover" technique. https://www.google.com.au/search?q=ASUS+Sabertooth+Z77+bios+battery This seems more sensible: https://www.youtube.com/watch?v=aSTTR_WVtx0 long video, but he's done it by 4 minutes in. Perhaps ASUS thinks that by the time the battery is crapping out, you'll have reached the stage of wanting to buy a newer PC. -- [tim@localhost ~]$ uname -rsvp Linux 3.9.10-100.fc17.x86_64 #1 SMP Sun Jul 14 01:31:27 UTC 2013 x86_64 (always current details of the computer that I'm writing this email on) Boilerplate: All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I only get to see the messages posted to the mailing list.
