W520 Win7 often crashes when lid closed

[pipapoh]

Hello,

i got a W520 and instantly bought a Samsung 840pro256 to replace
the 500gb drive.
I made a "clean" install with Thinkpad's recovery disks (so no mirroring).

When it is connected to AC and I close the lid, it is often shut down when I open it
a few hours later. When it got unplugged, its no problem.
Ernergymanager is the same plugged and unplugged.
I thought it is a firmware problem so I installed the newest FW of the SSD and made a
BIOS-update, but no effect. When I reopen the lid and start it with the button,
I can select if I want to start Windows normal or Safemode etc. Just like after a bluescreen or somewhat.

So I thought I threw out a few hundreads and cloned the SSD back to the normal HDD.
After testing it unplugged over the night, everything seemd ok. When I plugged it in at work and
closed the lid for a 2 hour break, I came back and Windows crashed.

SSD boots very quick - but I have to login at every website when I start the pc again.

Long story short - lid closed when AC-plugged - Win7 crash

The 'pad just should sleep when I close it. You know whats false?

Ok so laptop is unplugged and I closed the lid. After about 30min
I returned and the same problem - Win7 crashed.

I deinstalled the Energymanager of Lenovo now, perhaps this helps.

You might want to try to disable automatic action on "closing lid"

Putting it to sleep can be done by Fn+F4 faster than closing the lid.

I cant wake it up when I did Fn+F4. I can press any
keys but I end up power it off.

After deinstalling Lenovo's Energy Manager, i tested it today.
When its plugged, it shuts down when lid closed after a few hours.
Sometimes it happens unplugged too, but not that often.

Yes, S3 and S4 are different settings and each can be set different for plugged in / on battery in each profile.

I can wake mine up with the powerbutton or with the Fn button when it's in S3.
