    i am having an asus x80n laptop which doesnot startup and i mean when i press the power button it gives green light on power indicator and on the on indicator for a second and afterwards it gives no response,when i try to again press the power button it totally gives no response and you have to take the battery out or power supply out to have the same one second blink response .the condition of this notebook was not this same it was working fine but when i tried to start it again in the morning it didnt start but the condition was different as to previous stated means i pressed the power button it went fine through the stages like blinking the right indicators through fan getting on but it got stuck before when the asus screen comes leaving me with no response on screen,i read many places on the internet that its solution is to press the power button for atleast 45sec without batt...etc i did that for 3 to 4 times and it worked but that was just a luck because it did the same not getting start thing again and again leaving me in a state that it will turn on when it wants so i used it with some fear and i installed new windows and i restored all the bios settings to manufacturers so this laptop which i love now goes in a more meanner and bader phase when i left it in standby mode ,it was stuck there so i switched it off manually but again i managed to turn it on but at the other day when i pressed power button it gives or blinked lights and shuts off but then again after trying and trying i managed to get it on but now i am completely stuck with on light blinks for just a second an thats it no progress i really need help as you see and will appreciate any assistance

    Before you tear apart the block that sounds just like your battery is dead as you hit the power button it drains the last voltage left and dies. Have you checked that the AC/DC supply is ok? If its not getting power to the laptop then thats why its having this problem. I would have though you would get no response if you Mobo is melted.

    Edit: Try wiggling the power supply in the laptop and see if you get a battery charging light? Or if it flickers that would tell you the connection is faulty.

    Firstly is your Laptop under warranty? If so dont open it up, secondly I cant help you with the dissaembly but i would assume its pretty straight forward to open up most of the rear sections to get to the hardware. I really doubt its the mobo so if its other hardware these should be easily accessable.

    The only other thing it could be is your LCD screen, I read somewhere that this happens when the LCD screen goes to turn on but cant and shuts down you will have a few seconds prior to the video card turning on. The way to test this is to plug the external port onto a tv and run the laptop through that when you turn it on.

    The removing battery adapter and holding the power for 30 seconds is just draining the remaining voltage from the notebook I dont think this has anything to do with your problem if you battery is charging and it makes no difference your problem I reckon lies with your video card or screen.

    Test the above and let me know. If it does the same on an external screen then it sounds like your GPU is fried.

    Have you tried removing the GPU and powering it up yet?

    As I said above I doubt it going to be anything like what you have removed and doubtful its the Mobo. Its going to be the video card. Remove the GPU and power it up and if it starts but with no screen there is your problem.
