I have a Lenovo Flex 2 14 with i7 4510u processor. My laptop won't turn ON anymore, I tried the hard reset etc (removed the battery, AC etc). Out of warranty. My local computer repair guy told me motherboard is gone. All the i7 is close to $200, so I'm trying to see if there are any other compatible motherboards for this model. Can anyone suggest compatible motherboards for flex 2 14? It seems to me i5 4210u 1.7 GHz would be right. Experts please give me your opinion.
