I have a Dell Inspiron N5110 laptop with an Intel® Core™ i5-2410M processor. I am interested in buying an i5-2430M processor on eBay for a friend but I need to test it on my laptop. The problem is that the seller has no feedback so I can't trust him but this also means that the price is much lower than normal.

The processor he sends me might be faulty so my question is: Can a faulty [in any way] processor break anything else in my laptop?

P.S.: I know how to install it / apply thermal paste / not bend the pins / protect against static discharge so you can take this out of consideration. Thank you!

Yes, in theory it could break your machine; it's circuitry, so it could cause a short! I've had this happen to me (at least, this was my opinion, the techy person I spoke to at a computer shop (sales) and a computer repair technician). Don't get me wrong, I'm not implying it's likely (and IMO it's pretty rare), but it is possible to cause damage to the board or maybe some components of the board).

Yeah, I'd say possible but rare. Probably less likely than causing damage due to a screwdriver slip. – Daniel R Hicks Sep 27 '13 at 11:20
Totally agree Daniel,... we didn't believe it either but, it was the most probable cause! – Dave Sep 27 '13 at 12:03

No, you will be safe as long as you install it properly.
