I consistently experience random shutdowns with my Thinkpad Edge E520. However, the shutdowns only seem to occur when it is connected to the Lenovo USB 2.0 Port-Replicator with Digital Video through which I link the notebook with a Lenovo monitor and a Lenovo keyboard.
So far there have been no shutdowns when the notebook is running on its own without the port-replicator. However, I mostly use the notebook with the port replicator so that this observation may not be representative.
Is it possible that using the port-replicator leads to shutdowns? Has anyone any experience with that?
A different potential source of the problem may be the RAM: One RAM-card is manufactured by Samsung, the other by Kingston, the latter having been added by the PC vendor. Does Lenovo actually manufacture the RAM-cards it sells in its own shop or is it supplied with RAM-cards from another RAM-card-manufacturer like Samsung and simply labels those with Lenovo stickers so that it doesn't make a difference which one one buys?
Could the recovery of the system software help? I don't see how as Windows obviously recognises both RAM-cards and the Lenovo RAM-test confirms them as fully operable.
