Sanjay Mahabir :
i am a pc tech. and studied the problem for years now and wat is happening is the motherbord from gateway or acer do ware down with heat .so in other words the soilders tends to let go from the graphics card and turn cold causing the computer to detect no display but put the power out there to detect if 1 is attached .
SOLUTION to power on ( not fix the problem permanent but powers on )
do carefull as i say
it dont permenantly fix the issue but after a while doing so the card will be mended back onto the board when the pc starts to cut off while using and hot that means the sensors pick ip up as over heat .you might even get blue screen of death from time to time and sudden crashes but eventually it will be no more . try to maintain the laptop at a temprature that wont be to hot to trigger the heat sensor but hot enough for heat transfer.
let me know how it goes . mine and a couple i repaired work fine now .and i mean close to 30 + .
1 take out the battery
2 take out the power jack (charger)
3 wait 15 seconds as it takes 10 seconds to send pc back to machine state wait 15 seconds to be sure
4 get a piece of cotton cloth
5 press the power button and hold it for 30 seconds
6 then put the battery back in the laptop
7 connect the charger
now this is very important !
8 power on the computer then very quickly as soon as the power light comes on close the laptop lid ....( by doing this you manage to keep the system running do not open the lid as the process will have to start from the beginning)
9 wrap the laptop in the cotton cloth making sure to cover the vents of the fan not once but twice .(making sure the heat can stay in the computer )
10 wait till the computer get real hot like 30 munites or more the remove the cloth and just block the vent alone alowing the heat to transfer to the graphics card melting the soilders back onto the bord .
11 open the lid and hold the power botton till the laptop powers of and then power it on
12 hit start windows normally
if this help you plzz let me no... thanks
Thanks very much what you said worked. I wrapped it for 50 minutes just because that was the quickest i could get to it. And mine was done. At first it took a few restarts to work and over the weeks it got up to 15-20. This last one I couldn't get it to work after over 50 attempts.
A few questions: How long should I leave just the vents blocked after it starts up ? [i only did 10min. you didnt say]
Can I now use pc normally with shutdowns and sleep modes?
How long do these fixes typically last? and how many times can you fix it again?
thanks so much again and have a good day
