I have an Acer Aspire Z5610, which is now out of warranty.
It is a desktop type computer which has a very noisy fan. Particulary so when first switched on. It always requires a reboot, which cures the problem till the next day. But I digress !
Wonder if anybody knows the secret to getting into one of these machines, so I can see if I could replace the fan myself. It might be a specially designed fan of course, in which case I could not do it!
