That needs to be fully determined. If it blew the fuses without prompting then it's likely the owner of the replacement chip could sue for damages (the 'replacement' chip only in the machine to test the faulty mono/CPU argument).

Also, it would be complicated for Lenovo too as warranty and consumer laws in every country are different.

Everyone, thanks for the info, once I had a high opinion of the company but it's been going steadily downhill in recent years. Reckon I'd never buy another PC from them again over this nonsense.

Will it boot if you select no?
