Thinkpad X201 i5 CPU, 2.67 Ghz, 120GB SSD, 4GB RAM, Win 7 Pro 64 bit, Windows Defender, ( up to date Win 7 security updates )

Since July this laptop has shut itself down three times. The shutdown is instant loss of everything (shutdown) exept the power light (plugged into mains). Black screen everything stops. Today I was reading a PDF and the laptop was disconnected from the internet at the time (physically offline) of the 'instant off' event.
Looked in event viewer,

I see that in the event viewer there have been lots of warnings and errors leading up to these critical crash events. What should I do to stop this occuring ?

This X201 is a recent purchase from an ebay seller. He refurbs Thinkpads. SSD is a 128GB ( not 120 as mentioned above ) un-branded drive. There are no errors in device manager.
The seller writes;

'This laptop came to me with Windows 7 already installed.

As part of the refurbishment I perform a clean install.

I use Produkey to find and extract the Windows COA key.

I install Windows 7 Professional without all the baggage

and bloatware that comes with MS Windows.

I then use the original COA to reactivate Windows'


The laptop is put to sleep on battery power whenever I go out. It's used on battery ( un-branded long life battery) and mains power. I use my Lenovo PSU.

The SSD is only half full. This sudden shut down - no restart event is a first for me. I have no idea whether it's a hardware or software issue. Windows seems ok after I restart manually. Could it be the low cost SSD or battery ? The kernel is throwing a lot of errors so I'm guessing a OS software issue.

So far there have been no further Windows 7 crashes. Read a lot of 'help' topics and was reminded of sfc. So opened command prompt as admin and sfc /verifyonly showed an error which was fixed by sfc /scannow.

I've no idea whether it will fix the crash problem. Time will tell. The Event viewer is still showing kernel warnings and errors.

A new oddness is that since the sfc check and re-start, a watermark is now showing at the bottom right hand side of the desktop screen. Windows 7 Build 7601. Windows is showing as activated and works nornally in user and admin mode. I tried a couple command prompt lines from sevenforums but they failed to remove the watermark;

Is this message showing because this is a reactivated copy of Windows ?

(I also removed the RAM and cleaned the contacts with isoproponol solution then re seated )

How would I remove this message ?
