Most likely it is overheating.
check to see if you hear the fan working.

also- check the System event log to see if it is reporting on any malfunction:
right click on My Computer and select Manage --> click on Event Viewer --> System log

Connection screen seems to be broken ASUS X52JR


Try shining a bright light at the screen. See if there is movement. If there is either the back light has failed or the screen has been deselected, in which case go to the battery icon,right click and choose mobility. You can turn it back on from there. If not, order a screen through flea bay or wherever you want. When it arrives, pose the question again.

My led lights in my laptop emachine dont want to turn on anymore how i can turn it on again....its usually opens when i open the camera but now when i tried opening my video camera there are no lights...


Is the laptop working as normal? If so then it would seem only the leds are gone , most probably a power issue, I suggest you just call your laptop make , give them your serial and see if they can replace it

I have a Toshiba Tecra-M2-S410 machine, and it does not turn on anymore. When I remove the battery and plug it in, the power light turns green as expected. When I press the power button, two other lights...


Hi mohammad - seems the LCD of the laptop is gone bad . as u said u gets the light on the laptop and also sound and then it goes dark - shows possibly the LCD gone bad .
Give a try with this if you have a computer in your home - on the back of the monitor you will find a VGA cable (probably with a blue color end which goes to cpu ) unplug it from cpu and plug it in the laptop (side of laptop you will find a same input VGA slot blue color ) and boot your laptop after turning on both (monitor and laptop) if you find the screen on the monitor then it will be sure that your laptop LCD has gone bad .
On your laptop if you are not able to find the boot screen also that refers to LCD brokerage -anyway try the above you will be sure ..

The screen suddenly became blank....and it turned off...its not starting again


Major hardware fault. the laptop must be opened and tested - if you're lucky it's only a failed memory module. If it's , as usual on this models, the mainboard then it will be very expensive to replace.

HP Pavalian laptop screen gone black and blank.


It seems like the lcd back light may have failed can you see a faint image on the screen when you look really close, try it with a torch. If you dont see even the faintest image the inverter has failed and needs to be replaced. If you look on youtube again and search for videos of replacing both the back light and the inverter it will give you some info on how to change them. Do a google search for hp spares and you will probably find what you are looking, i think the inverter is about £30 and the back light is bit cheaper. hope this helps.

Battery has gone dead. When I plug the A/C cord in the light on the charger immediately goes out and won't charge battery.


try connecting ac adapter alone without the laptop, check if ac adapter light will stay green or blue.
try another power outlet using the ac adapter alone without the laptop check if the ac adapter light will stay as green or blue. if all fails replace ac adapter.

if ac adapter stays green or blue try connecting to the laptop without the batt, check if the ac adapter light will stay on, if yes then try connecting ac adapter to laptop with the batt plugin check if the light stays green. if not update the BIOS. if fails replace motherboard.
