    God, it seems that I've had nothing but problems with this laptop and Dell support is beyond horrible. Don't get me wrong, I love this laptop but I shouldn't be encountering any problems!

    I installed a fresh copy of Windows 7 last night (I had 1 license left for Ultimate and I needed to use XP mode) so I gave my laptop a format. I installed all the drivers, everything was fine and dandy. Benchmarks were great, PC now starts up with no problems whatsoever. BUT..


    When I hit shutdown, my PC just reboots. Now, you know whats weird? This is triggered from the AC Adapter. If I remove the AC Adapter, the computer shuts off as it should with the alien head blinking twice before finally going down. Plug the AC Adapter back in and the alien head remains blue and then the computer magically reboots on its own. Does the AC Adapter have too much power that it needs to shoot it off to the computer or what? I've installed every single driver and did everything correctly by reading peoples posts on these forums. I tried calling Dell but in the end of the 30 minute talk I was ready to shoot the person I was talking to as they knew nothing and were just wasting my time.


    I tried searching the forums but noone had a solution. Some people also figured out this was triggered via the AC Adapter. I've tried the power drain trick, it's good only for that 1 time you boot it. You shut the laptop off again, it will reboot. It seemed that most people on the discussion I saw had the Nvidia GTX 260m, but I have the ATI Radeon 5850 on the latest drivers that were released by AMD.


    Here are my computers specs:

    8 GIGs DDR 1333 mhZ
    i7 740qm
    ATI Radeon 5850 HD
    Samsung SSD PM800

    As I remember there was a BIOS setting to keep the computer online while plugged in. However I don't remember the specifics, it may be worth checking it.

    Sounds like a BIOS issue. ^^^^^May want to look into it further.

    Strangely enough, its usually a graphics driver issue. Try rolling back to the dell ATI drivers, and see if it does it.

    No it's not the BIOS, if it was it would have happened before I did the format. I'll try my ATI Drivers.


    EDIT: Well, I uninstalled my drivers, and did a fresh install of the latest Radeon 5850 drivers from AMD's site with the workaround tweak and now the issue has stopped. Fingers crossed right?
