So who pays if you don't have the smarts yourself ?
I would assume most people reading this would be capable of using another source to Google to read up on how to fix it, and apply it (although I have to say I have idea how to recover a borked BIOS).
What about your man on the Clapham Omnibus who has to take a Clapham Omnibus to his local PC repairshop, and be charged by them to implement the fix ? Which could easily rack up to £100 before blinking.
This is on top of the fact that any time anyone loses on this isn't recoverable in UK law.
