AFter one hour working, am going outside and my laptop working in my home, bur not sleep, after 3 hours am back in home, my latop was not sleeping and my touch pad not working!! Im trying to activate with FN+ F9, but still not working, restarting and looking in bios and there touchpad was enabled. Im trying with xp live cd, and there touchpad not working too, im trying with in setup of windows 7 and there touchpad not present My laptop is in ideal condition im disapointed about this..please give advice how to fix, im thinkng its not software problem, may by the motherboard not recognize touch pad ..how to reset bios ? please help..thanks in advice. I FORGET 2 days agoo i was updating bios with 320 and everything was fine...and i was mount extra 4gb stick ram 1333 kingston..and everythings working fine with 8gb ram couple dayz, but yestarday the touch pad is dead please help.. This is my model: K53SV-SX379D, and is there a way to downgrade my bios from 320 to 315? I suspect may be this will revive my toouchpad

 

You can downgrade the BIOS by using Easy Flash from the BIOS setup menu. Just make sure you have a FAT formatted USB stick to put the unzipped BIOS image on. Do not flash from NTFS. See: http://forum.notebookreview.com/asus/174395-bios-update-guide-asus-notebooks.html

Resetting the BIOS to defaults is easy, just hit F2 as soon as you turn on the computer, and then select 'Reset to user defauts'

You might want to try your original RAM. Maybe there is a compatibility problem.

 

ALLurGroceries, thanks for thr reply Easy flash not working, its tellin me the bios file is too old(trying with last and 315 bios file) , im trying with original ram and touch pad still not working. Any ideas? Win flash tellin me the same bios file is too old..i dont wont to send my laptop in sevice, maybe the problem is in bios, but there is no way to remove motherboard battery to reset bios...sad story only good think is my wireless logitech mouse working , but its not the same

 

Maybe I am wrong about easyflash letting you downgrade. I haven't had to downgrade BIOS in a long time.

You said that the BIOS update did not exactly coincide with your touchpad dying. So downgrading the BIOS may not be a solution. You can try the aflash method: http://forum.notebookreview.com/asus/174395-bios-update-guide-asus-notebooks.html#sec:aflash

Did you try your original RAM?

 

I just downgrade bios and now is 315 with afudos, before was the last 320, but touchpad and buttons still not working Im thinkin maybe the calbe of touchpad is reconected and there is no connection is it posible? Im wondering do tear off the keyboard and check cables..any ideas?

 

Yes that is possible, for sure. If you take off the keyboard the touchpad connector should be accessible. I am not sure if your keyboard is mounted from the top of the case, or from the inside, but if it's from the top you will see some tabs at the top that you can release with a small flat object. Here are some directions I wrote for another model:

Ok, i just remove keyboard, and thecables was on the right places, but i guess was bad connection, because i just unplug touchpad cable and plug it again andddddd yahuuuuuuuuuuuuuuuuuuuuuuuuuuu its a wonder my touchpad working again!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ALLurGroceries, thank you very much for your help, im very grateful, tnaks again. hmm, but the story is strange...my asus is 4 month old, and its in perfect condition, no scrathes, no hits on body,everythings fine,but touchpad stop working whitout reasons..strange, bu t i hope to working for a long time thank u again, wish u alll good

 

Yeah usually they tape down the connector with a little sliver of tape. If you get that problem again you can use some electrical tape or gaffer's tape to hold it down. Basically anything except duct tape or scotch tape as those leave nasty residue.
