My Acer extensa 4420 can't start anymore.... when I press the power button.... it seems like it starts searching for the hard drive... I have no video.... no sound.... nothing.... and then, it restarts alone. I guess he tries again.... but it shut down after the second try.

    I have the same exact problem. Does anyone have a solution?

  • cemons Sep 13, 2008

    I have the same problem as well, I bought My laptop the other day. It started fine out of the box. I initialized windows and used it for a couple of hours. I also updated vista with all the recommended updates. I went to restart the computer to install the updates and the machine tried to power up, restarted then shut down. I trid the power button several times until it finally started. On startup I got the screen that said windows was not shut down properly. I booted as normal and the system started fine. I have been having this problem intermittently since. I am unsure whether this is a hardware or software(windows) problem.

    Have brand new Acer Extensa 4420; purchased 4 days ago. Out of the box it was fine; started right up. Now whenever it hibernates or shuts down, it is does not want to restart. Acts likes it tries and then quits trying and shuts down after a few seconds. Have to do a power reset every time I want to boot up. Very frustrating.

    the same problem!

    All of a sudden my Acer Extensa 4420 just powered off. Each time I pushed the power button to restart, it would start then stop in 2 seconds. So far I have not gotten it to start again. What is a power start up.

  • khanrad Nov 21, 2008

    I have the same problem. Mine never worked out of the box. I can't get it to boot up even once to replace any drivers.

    On the acer web site it says to remove the power cord and to take out the battery. Then hold down the power button for 15 to 20 secs. Put in the power cord and turn it on.
    If that does not work. Take out the cord again. Put in the battery and plug it back in again and turn it on.

    That does not work for me.

    I sent mine back to Acer, apparently they are having a huge problem because the motherboard is backordered and I've seen several people with the exact same problem.

  • picksix Nov 28, 2008

    Same problem! I bought mine less than a month ago and it was fine until today. Went to start it up and some lights flickered for a few seconds then it just shut down. No splash screen screen, nothing. Tried the Support Desk solution they have at acer online but it didn't work. I'm very upset because I'm seeing many others with this problem and I'm not hearing very encouraging things about Acer Support. I researched this unit before I bought it and it had rave reviews but I guess we all got duds???? Luckily it's still under warranty but I'm afraid the problem will just keep recurring and once it's out of warranty I'll be screwed.

  • CmdrK2 Apr 22, 2009

    Same type of problems. With the power cord plugged in, sometimes it will start to boot and then shut down. Take out the power cord and I have a 50/50 chance it will boot. Will someone from Acer post something about this problem?

  • iura May 11, 2010

I think the problem is with the ATI Video drivers. I had the same problem and I went to the ATI site and updated my drivers and the problem has not occurred since. Mine was ATI radeon x1250. Windows Vista Home Premium 32-bit. The graphics card is integrated on the mother board.

    I have tried everything to get my extensa to work. At one point I was ready to ebay it for spare parts. However through trial and error found that the CMOS battery was one of the problems. I used duct tape folded together to secure the battery in place - not to tape it down but as a spacer between top of battery and the laptop cover. I can verify that this works. Machine now boots everytime. Unfortunately the screen would still go blank after the laptop booted - sometimes right away other times it would be okay all day before going blank. I ended up loosening the screws to the heatsink and the laptop has been running great. It has been up and running for a couple days now without any blank screens.

The problem is not with the graphics card it is most likely with the cmos battery socket. The battery is loose and that is why it may come one at one time but not at another time. And that may be why you don't see any bios splash screen. picksix's problem sounds the most similar to mine. I just opened it up and taped down the battery with some paper or anything non conductive that can add some pressure onto the battery and keep it in place.

    The big question is how do you get to the battery? I don't see it from the bottom.
    Do you have to get under the keyboard and how do you do that?
