Somebody has given me an Apple Macbook Air 1.1 to fix. Unfortunately I have very little experience with Macs.
*Computer runs incredibly slow to the extent that I have never seen one so bad. Boot up time is about 15-20 minutes then once logged into the GUI every move is agonisingly slow.
*Battery does not work/charge or is not being recognised
*Fans running super-fast
*When run in verbose mode very many I/O errors on disk0s2 are seen during startup
Things I have tried:
Reset VRAM - no change
Reset SMC - no change except keyboard backlight started working (didn't even realise there was one)
Checked available disk space - About 40GB out of 80GB available
Tried to run in safe mode - no change
Tried running Apple Hardware Tester at startup (by holding down D, also tried Option+D) but cannot seem to access it, possibly because the system is running so slow.
Used disk utility to repair hard disk - no errors/problems found
Checked SMART status of hard disk with Disk Util from the command line - SMART status reported as "verified".
Since there are continuous I/O errors but SMART status returns as OK should I presume that the motherboard is on its way out seeing as other things like battery are also not working? Or could there still be an issue with the hard drive / SSD?
