Windows 7: Plugging in notebook computer causes stuttering

Plugging in notebook computer causes stuttering


I have this weird issue where my notebook starts to stutter after coming out of hibernate whenever the power is plugged in. The mouse doesn't move, the audio goes out, videos stop, and sometimes I get a black screen that disappears in ten seconds. Sometimes after the black screen I get a message saying my video driver recovered. I am running a nVidia 8600M GT with up-to-date drivers. The problems usually resolve if I restart but it's really irritating that I can't get out of hibernate without this stuttering. Switching back to Vista also fixes it. I've tried reinstalling drivers and reformatting with a clean install of Windows 7 neither of which helped. I didn't have this problem with Vista although I had another power issue in Vista (which I still have with 7) where if I put my computer into hibernate with the power plugged in, the computer wouldn't start again until I unplug it and take out the battery.

Would be great if someone could give me an idea of what's going on. Thanks!

Did it just start doing this recently?
If so then you could try doing a system restore to an earlier time and see if that helps.

What is your model of your notebook?

It might prove helpful if you fill out your specs if you have any other related issues.

Try changing the power settings on your system from the default power plan to the High Performance power plan, then just change the settings so its identical the the prior power plan. Thats the best i can think of...I had an issue similar to that with an HP dv3t and upon unplugging the whole system would studder until i did a cold shut down. If that doesnt fix it, it could be a motherboard issue.

What if you use Sleep with no Hibernate? Then what if you use Hybrid sleep and nothing else?

I would run through these troubleshooting steps which cover most probs:

Always test hardware on persistent problems:

Since it doesn't happen in Vista it doesn't point to memory, but I'd test my RAM anyway using memtestCD for 5-6 passes or overnight.

Then I'd test my HD using maker's full diag/repair CD scan:
