Compaq laptop - out of power supply

I was in the middle of my work when my compaq laptop went off - as in total black out. since then it didn't start at all. Seems the power supply is not working. Do you have any idea of what is wrong with my computer? I reside in Davao City Philippines. do you know of a nearest Compaq service center, where i can have it repaired? thanks

Probably the plug is damaged or the adapter is out ..cause in any other cases it would worked with the adapter in ..even if thebattery is out ..
if there is no light on the stand by ..or other lights control ..than you have to see if the adapter is still functional to eliminate this issue ..after that try to charge the battery in another one and see if it still works on batteries at leas...If all that done ..and it still not getting power at all...Not necessary start ..but see lights or such ..than it is not a power issue but the motherboard has a damages either on the powering line ..or the CPU itself..

Compaq evo 610c laptop.....screen went black no power to computer, power supply checked ok, wireless modem fried. would computer be re storable or is it total loss


Sounds like the logic board got shorted out. (Probably how the wireless card got fried)

I'd pull out the HDD, the CD/DVD drive, and try to sell the rest as scrap. Some people need a spare screen.

To answer your question. Not a total loss, unfortunate, yes, but you can still make a few $$$ on selling scrap via ebay, or some specialist buyers. (easily solved by a google search)
Be sure to backup your data using another computer before getting too far ahead of yourself.

Screen went black...rebooted, computer seems to


Remove the battery and disconnect the power adapter for about a minute.

connect only the AC then boot it back up. If you can see the Compaq splash screen and still unable to load Windows, re install OS.

If you could not see the splash screen, too bad it could be a motherboard issue,

Hope this helps.

Black Screen, No Sound?


Hi i have the same tv mine did the same thing, it seems it may need a new power supply or there may be a power issue with your tv which is inside of it if buying a power supply does not work then it is the tv and it is expensive to have it fixed. fortanitly mine was just the power cord but yours could be something more. You can buy a power supply off ebay for 34.99. Hope this helps.

sounds like a bad screen this might be able to be remedied by hooking the laptop straight to a computer monitor threw the ports provided in the back
also you could have bumped something loose inside like a video card if any cards or memmory comes loose this will give you black screen of death the laptop will have to opened and cards pressed down gently
theres the solution of your power supply on the laptop went out and you need a replacement
if power supply went out it doesnt hurt your comp it just makes it hard to run

Dead laptop


Check the ac adapter is the proper one for that laptop. Check the power jack is not damaged or loose. let laptop site without battery or power for a few hours. remove battery and retry power. try another ac adapter if that doesn't work, you may have a reset button but not likely to solve the problem. sounds like motherboard is damaged, or something blew.
