Laptop won't power on?

"I am looking for lid switch symptoms for lcd that looks like a bad backlight"...

Can you see an image at all on the LCD panel using a flashlight?

I know this is an old thread but thank you so much! I created an account just to thank you. My laptop died-wouldn't turn on, changed the battery. Nothing. I googled it and your tip is what did the trick. I was getting ready to shop around for a new laptop (probably more so because I wanted one anyway) but needed the files off of it either way. Thanks again!

Hi guys, I need help.
My Samsung laptop just stopped working suddenly. The battery was charged when I switched it off last night but it wont start in the morning. I tried using different adapters but the charging lights wont come on. nothing happens when I press the power button - no sound, nothing. There are no lights blinking in the laptop. It is my official laptop and I have all my data in it. I dont want to lost it. Please help! Thanks in advance

I have a Gateway MS2252 laptop. No power getting to pc, either woth adapter or in battery. Worked fine yesterday. Tried ESD, no luck. AC/DC adapter light comes on. When I plug the adapter into the laptop, the adapter indicator light immediately goes out. Any ideas? Please help

I had a similar problem and it turned out that my battery was empty, so I just charged it for 5 min and all was good. Make sure that your charger is actually charging the battery since the AC plug falls out easy

I have had the same problem with computers before, and dell tells you to do the eraser thing...which doesn't work at all....remove the battery, remove the a/c adapter, hold the power button for 20 seconds to remove all static. Then here's the kicker...take a Qtip~ apply a VERY SMALL AMOUNT OF ALCOHOL, gain access to the ram, clean the gold connecters thoroughly, DRY THOROUGHLY!!! Then clean the mother board connectors the same way...DRY THOROUGHLY...DON'T BLOW ALLOW TO DRY~~~DON'T APPLY LARGE AMOUNTS OF ALCOHOL, JUST ENOUGH TO CLEAN...you will be amazed how much black crud comes off....ALLOW TO COMPLETELY DRY!!! Reinsert the ram making sure good contact is made. Return the cover. Replace the battery, and your computer will/should come back on and charge if not a battery issue, r/c adapter issue or mother board issue...computer repair stores do this all the time and charge you big $$$$$$. If nothing else works, what do you have to lose. JUST DON'T APPLY A LOT OF ALCOHOL, OR GET IT TOO WET. I picked this up from another computer repair shop.
