Please help me, I have Acer aspire one AO722. I download driver from acer support but I don't know the driver for BIOS and make my BIOS downgrade. And now my laptop black screen

Can anybody here help me to fix my problem ?
Thanks

 

Good luck getting an answer. I posted with the same problem over a month ago.
No hits...

This was the only thread where there was at least an attempt before I posted my request: http://www.laptop-forums.com/aspire-one-ao722-bios-recovery-t23653.html
Unfortunately there seemed to be unclear steps.

 

Take a look at this post from the forum

Possible ram static?

 

The D255 topic proved most interesting, not least because it gave access to the D255 series Service Guide. This is very helpful but access to the AO722 Service Guide would be even better. Any ideas?

Thanks.

 

Two video links that could help

Thanks, but I'm really looking for the Service Guide for the 722. If it's anything like that for the D255, it will give me a fighting chance of servicing the 722 if I have a problem in the remote places that I tend to visit/stay.

 

There's no listings I can find on the internet for a AO722 service manual.


The most servicing type thing you can do is replacing the harddrive , ram , screen , or in extreme
circumstances, the dc jack connector, or bios chip.


The main thing is keeping the fan and vents clear.

 

Thank you. I have done all the searches and yet, it's out there, just as the Service Guide for the D255 is. There is a lot you can do with or without the Service Guide but it's easier with. I've serviced my own electronic equipment since the days when the Mullard OC71 was a 'hot' device and I'm not about to stop now.

 

Good for you
if you could post the ao722 manual link
it would help other members
