We have a Toshiba Portege R500 Laptop unit.
From the above thread, it seems that in order to run XP Pro on the laptop we have to change the SATA controller mode to Compatability rather than AHCI.
We have done this and successfully installed Windows XP.
Then...after a couple of days we log on and the mousepad and keyboard don't work. The laptop boots up but there is no mousepad or keyboard.
We then re-image the laptop and again, the unit works for 2-3 days and the same thing happens.
What could the issue be?
