See if it's under warranty, if not then contact the seller and tell them of the problem, since it's only been a week you can possibly file a complaint with paypal saying the laptop is faulty.

It is a known motherboard issue, the batch of Extensa 4420 manufactured in late 2008 had defective motherboard installed. Just call Acer repair and send in the computer as I assume you are still under warranty. I just got back mine with MB replaced, everything works fine now.

Hi . I have a extensa 4420 which I bought last year and recently I was having same problem like many of you. When I turn it on it would flash hdd and cd light and after few seconds it shut down . Sometimes it would power up but more frequently it didn't. I red many posts and tried all possible but nothing worked . So I thought maybe there is a problem with CMOS battery . So as a last resort I took whole notebook completely a part. Look at the battery model , recheck ALL possible connectors to motherboard and pushed on them to make sure there are properly seated. After that a have put everything back together and tried to power it up . It came up right away without a problem. It has been two days and not a single problem. I tried to power it on and off more than 30 times ever since and it still works . That tells me that ether CMOS-battery or some connector to motherboard or maybe even memory was not seated properly . It may have got lose carrying laptop around. I hope it will help at least to some of you .

Please be careful if you decide to take the notebook a part .

I'm having a problem where when my laptop (same model), after going into sleep mode, when powering back up to resume, it loses track of time (goes back to January 2006)....checked the BIOS which also seems to be changed to this time...I change the time back to current time then restart computer it is fine until going back into sleep mode which then sometimes problem reoccurs. now thinking could also be a problem with the CMOS battery seat. Does this problem sound like similar or could be a cause of this. How do I get to the cmos battery to check it? Thanks.

CMOS battery is under the keyboard . But you will have to take the whole notebook a part . Go to the link

You would be very suprised how effective a power reset is on any electronic device! Anything using a battery/source of power and has capacitors in it this will work for. Unplugging everything and discharging the device, usually by holding power button down, making sure no power source is installed (e.g. battery, power cable) for 30seconds and then plug it back in. I have had this work for many of my past owned laptops and worked for me when my old iPod locked up lol.
