    I have a Sony SZ160P/C. The computer is working fine on AC power, but will not run off battery. When I am on AC power I go to Control Panel/Power Options/Power Meter and it indicates that no battery is present. I have tried reseating the battery many times with no luck. I called Sony and they said to reset the BIOS back to the defaults and I which I did and still no luck. Now they want me to send it to San Diego for service.

    Has anyone else had this problem or have any suggestions that I might try. The computer is 3 months old and the battery was working fine a few days ago, The only software update I did was download the Nvidia driver update from the Sony site a in the past week.

    I appreciate any input on this!

    Try cleaning the contacts. I know it sounds silly, but it's the most basic-est of things you can do. It's a starting point. Also check if the battery is all the way in and locked.

    As of yesterday at work... My SZ120 is doing the exact same thing. This notebook is 3 months old and for whatever reason my SZ can't see my battery any longer. I have checked to make sure that the SZ is still powering the battery connection pins with a multi-meter and indeed it is. So... if my notebook is properly applying power to charge the battery... and the battery worked fine all this time... is it possible for a li-ion battery to just "die" like this. I am stumped and I really don't want to send the notebook to sony if there batteries are just prone to failure sometimes. Thanks in advance for ay ideas.

    I also had this same thing happen to me a while back and I never did find a definitive solution. Only after reseating and powering down/restarting the notebook countless times did it finally recognize it again. Very frustrating.

    I just don't get it. I can't understand why the battery would just stop being recognized... out of the blue? I am going to try to go by Best Buy tomorrow and see if they will let me put the battery from there floor model in my notebook. If THAT battery will charge, at least we will know semi-for sure that this issue is indeed battery related. WIERD?

    I usually use my SZ-160 either docked at the office or at home, and only run on battery power a couple of times a week. Last night I tried to turn on the system with the battery and got *nothing*... not even a little blip. Dug out my AC adapter and the battery charge LED doesn't light, but if I press the power button it fires right up. The XP power dialog reports battery power remaining as "Unknown" and battery #1 as "Not Present".

    Removing the battery and reseating it makes no difference. Has anybody seen this problem?

    While I do not have a Sony laptop, I'm going to spit out a suggestion or two:

    1) Make sure you fully charge the battery (though I'm assuming it was since you leave it plugged in all the time).
    2) Wiggle the battery a little (if you can) when inserting it into the notebook. I've heard that (and correct me if I'm wrong) that some models have loose batteries.

    It's possible that either the battery is loose enough (or damaged enough) that it isn't making contact, or the contacts on you motherboard are damaged. Do you have a friend with an identical battery? If so, try theirs out and see if the problem still exists.

    Are either of you geting any sort of pop up window about a bad or incompatable battery? I know that has been addressed on this forumn. Do a search for battery issues. You will get a lot, just weed through the exploding batteries and you should get some missing battery posts.
