    P2140; wont resume after hibernate

    Hey guys, been having this problem for a long time now and cant figure it out. This is one of the last problems I need to figure out before I have a smooth running carPC!!!!

    My computer wont resume (when I turn the car on) after it goes into hibernate (when I turn the car off). Instead, it will start up and show me the Windows Error Recovery screen. It will only resume properly if the computer did not resume from hibernate previously.
    Sorry, its kinda confusing to explain, but its simple. Here is what happens:

    - CAR ON = Computer starts normally (resumes).
    - CAR OFF = Computer goes into hibernate.
    - CAR ON = Computer starts in Windows Error Recovery screen. Then eventually starts normally.
    - CAR OFF = Computer goes into hibernate.
    - CAR ON = Computer resumes.
    - CAR OFF = Computer goes into hibernate.
    - CAR ON = Computer starts in Wndows Error Recovery screen. Then eventually starts normally.
    - CAR OFF = Computer goes into hibernate.
    - CAR ON = Computer resumes.
    - REPEAT!

    Basically the computer cant resume properly every-other time I start the car. Which means that it wont resume after it has already resumed once from hibernate.

    Blah! Thats probably more confusing than it needs to be lol.

    Can anyone help me!? I'm no computer expert at all, but I'm guessing its a hibernate or resume setting in BIOS or Windows I need to change? I cant figure it out. Btw I'm using Windows 7.

    I just spoke to an IT guy here at work, he was too busy to get in depth with me. But he said in BIOS under Power Management Settings to set it at "S1 + S3"? Does this sound right to anyone?

    S1+S3 sounds right. Your BIOS is probably already configured correctly, since the computer will sometimes enter hibernation and resume.

    My first thought is that your PSU is cutting all power before the hibernation file can be fully written.
    I would try extending the time before the P2140 does a hard off and see if that resolves the issue.

    Additionally, less RAM may help the situation, since the hibernation file is the same size as your physical RAM. If you're running 4GB, reduce to 2GB and see if hibernation/resume is more reliable.
    Have you looked in the FAQ yet?
    How about the Wiki?



    Under normal circumstances, a signature would go here.

    Thanks Darque.
    You're right, the computer is not shutting-down properly after resume. Thats a much easier way of explaining my problem. **The computer will not go back into hibernate properly once woken from resume. It instead does a hard shut-down. It will only go into hibernate after being turned on from a normal shut-off.**

    So I tried prolonging the shut-down delay in PSUMoni from 30 seconds to 45 seconds, without luck.
    Then I tried removing one of the 2GB Ram sticks, however had no luck with this either.

    I haven't yet tried your BIOS suggestion, however as you mentioned, I have a feeling this is already configured correctly so I'm not so confident that will work either.

    Any other suggestions!??

    S1+S3 is a suspend to RAM setting, and shouldn't impact hibernation. S4 is the save to disk, ie: hibernation, setting.

    Have you checked your system logs to see if anything odd is happening?

    No I haven't checked the log, and dont think I even know how to do that. As I mentioned I dont know too much about computers, I was barely able to figure out how to put the Ram back in, lol..

    Should I try changing it to S1 + S4?

    Ok I figured it out. Windows 7 had a hibernation issue itself which was corrected by a simple update. My Windows 7 has not been updated because my carPC has not been connected to the internet yet.

    Issue fixed. Update Windows.
