Help: laptop slowing to a crawl when on battery

post #1 of 8
Thread Starter 
Hey everyone. At the end of the summer I bought an HP G72 laptop. I love it, however I find that it slows down when I unplug from AC power and run on the battery. It starts slowing down to the point where webpages take minutes to load, there's text input lag, etc.

I feel like it might be overheating or something. The stock hard hard drive was a 5400rpm drive, which I swapped out for a larger 7200rpm drive. Would that cause the overheating? (maybe 7200rpm is too fast/runs too hot for this laptop?)

Any ideas?

Besides the power consumption/heat issue, you might check to see (if you are running Windows 7) if the Aero Theme is slowing you down.

Had it act funky and choke the speed out of my HP as well. When it was running on AC, it worked great, but when the laptop was on battery only, it might as well have been a paperweight.

Disabling Aero seemed to clear it up.

It's not much, I know, but it may help.

Thanks, I'll give it a try.

I got rid of my aero theme and set up a basic one, and it still starts crawling when I unplug it. I'm really starting to think its the damn 7200rpm hard drive being too fast/too hot, but I'd like to hear more feedback before I go backing everything up and swapping the drives.

Try changing it to a balanced profile and see if it helps.

I went into the advanced power settings and tweaked some things. It seems to have stopped (for now), though probably at the cost of battery life. Oh well, I'd rather have a smooth-running laptop for an hour or two than a worthless lagfest for three or four.

Thanks a lot guys. Might be time to find a bigger battery for this thing =D
