Lap top was plugged in and working with full charge. Turned around and had blank screen and computer would not turn on.


I also leave it plugged in almost all the time, learned that can be bad.


Did this 3-4 times, took battery out and unplugged computer from adapter, held start button down for about 1 minute and tried to restart.


Used compressed air and blew into fans, a little dust came out.


Took battery out and tried to run straight from adapter – nothing


Replaced CMOS battery inside – nothing


Then took it to a computer repair store where they charged me $40 and suggested it was the CMOS battery or charger. So I purchased a new charger.


Plugged it in with new charger and turned it on. It worked and immediately showed the battery was at 98%. I ran a virus scan, disk cleaner, and played on it for about 1 hour. Then it died again.


When plugged in two of the lights come on white, and a third will some times come on orange. You can hear the DVD player clicking, but nothing works.


Was going to order a new battery for it, but curious why it does not work when plugged in to adapter without battery in.


Looking for any suggestions.

Even with the new charger you cant run it without a battery?


If you cannot run the laptop even with the (known good) charger minus battery, I would say the problem is with the laptop and not the battery/charger. Its hard to say with no information but I would say this is most likely going to be a motherboard problem.


Another possibility is that its just a bad screen. Use an external monitor and see if that is the case.

At the repair shop they said they checked with an external monitor and did not get anything.


Starting to sound like a motherboard.


Appreciate the input
