The usual is either cheap or expensive. When I get a dead laptop I like to know the story and inspect for dings from drops.
Then I do the battery removal BUT after the battery is out and the power removed I press and hold the power button for 60 seconds (yes, it's usually less but 60 covers all the devices.) Release the button, slip in battery, apply power and see if the LEDs look proper. Give it a few minutes to take more charge then test.
If this fails I install a new CMOS battery. I DO NOT TEST THAT BATTERY. It's cheaper at the shop to just change it and charge for the battery than test and incur a test charge (75 bucks!)
The reset is repeated and if no signs of life, depending on what we see we call it battery, charger or motherboard failure.
Hello
My laptop wasn't used for about 6 months, when I tried to boot it up again there was no response. I let the battery charge for about 3h before I tried to turn it on, the diodes are on and the cd-rom is responding but nothing else happens only when I plug in the charger there is one short beep also the same beep occurs when I plug it out. I tried to boot it using a pendrive with linux on it and there was no response, I tried taking out the battery but it didn't help. How can I check what is the problem?
