Question:
aspire 1680 usb power surge when plugging in ac
so far im loving this laptop... the only problem ive noticed is that i get a 'power surge on hub port: a usb device has exceeded the power limits of its hub port' error message whenever i plug the ac adapter into the back. this happens even if no usb devices are plugged in. all my devices seem to work fine, but this kinda worries me...
anyone have any ideas? thanks in advance...
edit: fixed usb controller driver problem! just had to automatically search... stupid me.
I reinstalled windowsxp pro on my aspire 1680, which came with xp home. I installed all the drivers that came on 'system cd rev 1.0', however, i still have an error for the 'usb controller' in the device manager, saying that the drivers were not installed. it seems that all my usb devices still work properly.

im running sp2... however, it happens when im plugging it into the wall, not when i put a usb device in. im on the phone with acer support right now, hopefully theyll tell the appropriate people and have this fixed up.
edit: nevermind... im so disappointed with acer support. theyre just searching off google! no doubt they would find this and try to tell me what im posting here. *sigh* they passed it off as purely a software issue. i hope thats the case...
Answer:
Since they're saying it's possibly a driver/software problem and you're running XP Pro, you may want to reload the original OS onto the system. If the problem persists then it's a hardware problem, since it's still happening with their supplied OS. If the problem goes away, then it's purely an OS/drive/software/config issue. Try reloading the OS in stages and see if it comes up with the same problem.
1. OS base install with minimal drivers
2. Install drivers a couple at a time an retry, if still nothing, move on, but if problem re-occurs, you have narrowed it down to the 2 drivers you just installed.
3. Personally, I'd leave SP2 off the system, causes more problems than it resolves.
Good luck!

Answer:
hey,
i have the same problem with the power surge in the hub.
everytime i plug it into the wall (acer aspire 1681wlmi).
i just got that lappy a month ago. i didnt reinstall anything. still running on xp home service pack 2.
the only usb devices that i've ever installed on the machine are my 128 usb drive, and usb mouse, which i rarely use anyway.
on my computer tho, the message "power surge..." shows up, but after about 5 minutes it dissapeares, and everything is back to normal. i dont understand it at all.
Answer:
yeah, it seems to not have any problems. its kind of worrying, but my lappy hasnt shown any problems. im thinking it might just be an annoyance caused by sp2. as for uninstalling it, my university requires me to be up to date or they disconnect me :| what problems has it been causing for people?
Answer:
i had the usb power surge warning a few times on my 1681 too. it seems to be a common problem for these models..
what i am really worried about is that when laptop is plugged in the battery charge is decreassing something like 5% in a few days. it doesnt seem to be a big problem but its frustrating
Answer:
charge dropped to 88% last week
but im not sure thats why i will leave it plugged in for a week to see the result
and yes i am using sp2,
thanks for the reply venom
Answer:
Green,
Are you running XP SP2 on your system or is it still SP1? SP2 is the cause of the problem. Below is the link to Microsoft's site that indicates this issue.

The issue with the battery dropping 5% in a few days on AC may not be too much of an issue. Some systems have a protection system to make sure the battery doesn't overcharge. It'll turn off the charging until the battery drops to a certain point and then kicks back in. If you notice that the battery continues to drop and doesn't recharge, it's possible your charging unit is defective. You should then get it checked out.
