hi,
my father sent me acer aspire 4730z from KSA almost a month ago. yesterday, i restarted vista home premium so that i could switch to xp 64, but forgot to select xp and vista started loading again, so i pushed the power button but this time the laptop won't boot at all. When i press the power button, nothing would happen and after few sec just a black screen. even the num/caps-lock wont work. dont know what went wrong, but i cant sent it back all the way back to KSA and i think acer has nothing here in pakistan..

hi.. yesterday i restarted my acer aspire 4730z repeatedly twice.now it wont boot at all.. i think the problem is with bios as everything else seems ok. it has Insyde bios and i have downloaded the rom files. but don know how to install it as i cant see anything. i followed many forums which showed how to install it on some other aspires. bt that does not seems to work for me. after fn+esc key and putting the usb drive it will shut down with the green lite still on.. what should i do?

Try this first: blank screen

If that does not help, tap on F8 as you power ON and go into Safe Mode. Try to go back to a restore point or try a Vista Startup Repair.

sorry but what you are telling me are basics. i tried that tho, but that did'nt work. the problem is, it wont even start to show me the POST bios screen. jusb a bluish black screen

hi,
http://www.techsupportforum.com/hard...ck-screen.html here i have told how the black screen problem occurred. now i m sure its because of damaged bios. but after trying so many time i am not yet able to re-install bios files. my laptop is acer aspire 4730z and i downloaded the bios files from acer and put those into a bootable usb flash disk but even after that fn+esc key procedure the laptop does not seems to detect it and powers down with the green lite still on.. any ideas what can i do to fix it?

TriggerFinger

Hate the basics?

I suggest you open the top lid, and swap the inverter with a good/working one. If after replacing the inverter the screen still do not work, remove the LCD and replace the backlight. This I hope is not basic for you.

On how to open the laptop and how to do the removal and replacement, I suggest you use a service manual. Unfortunately we do not have that here so I suggest you call Acer and ask them where you can download.

Btw opening it up will void the warranty.

thanks for your.... sujestions :( but i need some serious help, not some lame jokes about screwing/tighting my lcd. and i know my problem is not hardware based and sadly there are no acer retailers etc in pakistan..

TriggerFinger

I understand... and by the way, the suggestion was not a joke. It was supposed to test your LCD. But since you have concluded it is a BIOS failure then I must rest my case.

Dont know how you interpreted Trigger's fingers response as a joke; other than to surmise he submitted a process to try other than what you wanted to hear?

In order to corrupt a bios something has to be "writing" to the bios; which is why Trigger is looking at options other than bios corruption & quite accurately at that! Had you informed us you were attemping a bios upgrade and it failed; then we would be discussing bios flashing procedures.

I highly doubt your bios is corrupt, it's more like powering down your system while it was working may well have borked your internal power system or even messed up the hard drive so as to cause a PCB short on the drives logic board.

The plan of trying to flash the bios on an unstable system is also a very flawed plan, could well end with a bios that is truely corrupt which will require bios replacement and soldering.

You could try performing a cmos clearing, which requires gaining access to the cmos battery; on some laptops this is done easily on bay doors on the belly of the laptop, while other require removal of the keyboard. Reoving the battery and power cord and removing the cmos battery for about 15-20 minutes should do the trick of clearing your bios.

You could also try booting the laptop with the hard drive removed and see if you can get to a post screen then. Also try booting the laptop with the memory removed, and also with only one stick occupied soemtimes these tricks will wake up a confused bios or at least give you a chance to pin point bad hard drive or bad memory sticks.


Its still just as big a change the LCD is not working ? when you try powering up does the cpu fan spin and push air out ?

have you tried connecting to a remote monitor such as the one a desktop computer would use ?

unplug the ac adaptor, remove battery, press power-on button for 30 seconds.

TriggerFinger
