Aspire 7720-6395 Questions

I purchased my Acer in Dec of 2007. It's worked great except it's overheating problem (got a fan, no more problem). Last month it started intermitently not booting properly, and not coming out of sleep. I "fixed" the sleep problem by telling Vista not to put it to sleep any more. I typically shut it down when I'm finished with it so sleep wasn't an issue for me.

To ellaborate on the booting problem. If I attempt to boot it, the display turns on, and power button turns green, but neither the fan, nor Drive turn on, nor do any of the USB ports get power (I know this because I have an illuminated keyboard, which doesn't illuminate when this problem is occuring). I've waited for as long as an hour and it will never boot. If I hold down the power button for 4 seconds, it turns off. And if I boot it again it boots up properly. Doesn't matter how many times I reboot it after it always comes back up. I've never tested how much time passes before I can't boot it. I also tryed putting it in hibernation manually, that worked twice, the last time it wouldn't wake and had to be rebooted. I've done a check disk on it but all seems fine.

I did find a blurb about needing to upgrade my bios to 1.43. But since I don't know how to do that I thought I'd see if anyone had any suggestions or troubleshooting steps I could try first.

Thanx in advance.

 

If you want to update your bios go to
http://support.acer-euro.com/drivers/notebook/as_7720.html
Download the BIOS 1.45 or 1.43 (you pick), unzip all the files and run the exe and that's it (you might need to choose the updated bios), it will reboot and thankfully will solve the problem.
The sleep problem probably is because you need to update your graphic drivers, you can go to laptopvideo2go and find the latest there and "how to" guides. I am guessing you have nvidia graphic card.
I hope I was helpful

 

Thanks that was helpful. I'm not having a problem with it going to sleep since I changed the setting, though I know my workaround is aweful but since my laptop isn't left on I didn't figure it would be a big issue. I was able to find the BIO zip, before you posted and downloaded it. But I'm still hesitant to do it, from one obscure post. I know I'll need to when I upgrade my chip, so i really shouldn't be. But I am all the same.

I was really hoping someone might have some other ideas or diagnostic to try before I upgrade the BIO's. Thanks again.

 

I do also own a 7720, and the only thing that solved cold boot issue was updating Bios to v1.43. It´s a pretty safe procedure, I advice you DOS mode, it´s even safer (imho).

Kind Regards and good luck

 

1.45 is available as well do I go ahead and do that one or stick with 1.43 as it's proven to work? Also should I step the Bio upgrade up (mean update at every 3rd bios level.. ie 1.16, 1.21, 1.29a, 133, 142 etc.) or just apply 1.43.

Thanks!

 

Hi Shawna.

I´ve been using v1.45 since it came out as a beta version (3 months ago aprox), and no problems so far. The cold boot issue dissapeared since v1.43, but I was having some wi-fi disconnecting problem, which has totally vanished using v1.45, as well as cold boot of course.

Summing up, I would advice you to flash v1.45 under DOS mode. If you can´t do DOS, use the Winflash version, remembering to shut down all background programs before running it (antivirus shield, msn, etc, etc). I would also advice you to disable Hdd and System passwords from BIOS prior to flashing it.

Kind Regards and Good Luck!!!
