x201 shut down randomly [ Edited ]

[ghzallen]

I bought three x201 3249-ct0 at one and half year ago in UK from the Lenovo official website, I used one, and other two for my friends, recently, my x201 and my friend’s are all face the those problem:

-- Random shutdowns over the course of the past months.
-- Sleep usually doesn't work. That is, it'll shutdown.

--screen turn black if press sleep button.

what can I do in UK?
