Hello,
Before doing any of that bios upgrade mem stick stuff try the following. It's easy.
- Turn your laptop over.
- Remove the rear access panel.
- Inside you have; graphics card, fan, heatsinc etc, system ram: but most importantly, two installed cards that are about the same size. [Also maybe a small modem thing somewhere but forget that.]
One is the wireless lan card (Intel 4965).
The second is the Intel (turbo) memory controller: it has some drive application aswell, but forget that for now.
[These two cards I believe are on 'PCI' slots]
Remove the Intel memory controller card: it's not clearly marked but easy enough to decide it's not the wireless card. {No wires attached that are lead off to antennas}.
Turn your laptop back over - be carefull because you may not have replaced the rear cover. Press the power button to start the laptop. Does it work?
I hope so. Once your system is running you may try replacing the Intel card, and reinstalling the drivers 'if you need to'. It will probably all work fine.
P.S. Pure speculation but, did you by any chance try installing unidentical memory modules. The 5920 is dual channel symetrical, so maybe it upsets the memory controller. If so, I'm just guessing; I havn't googled for any insight on this.
I did however google the Intel memory controller to understand a bit about what it does. It appears unessential for a fully functioning laptop. Therefor if Intel mem controller is faulty, your still ok, It's got something to do with Readyboost and Readydrive.
