Having problems with your PC Laptops ?

Will not power on

\015 When I try to power it on, the lights will flash and then go off. If the button is pushed a few more times, the cdrom light will come on, and the power light stays on as well as the cpu fan turns on, but nothing on the display. I have plugged in an external monitor to no avail. I have try the function keys, no luck. I have removed RAM, cdrom HDD, try to check if it was RAM but get the same results. I just got it back from Gateway/Acer repair, but now past warranty. They did replace the motherboard and RAM as well as HDD. It was working fine one day until I updated the system and when it rebooted, it shut off and would not turn back on.\015

Answers :

As you have enough knowledge to take your laptop apart and remove items to track the problem down, my first suggestion is to make sure that the graphics chip/card is seated properly. Poor re-seating during repairs is one of the most common issues. It may have been seated enough to work for awhile. When you updated the system was it a BIOS update or BIOS and graphics? Often when graphic cards are updated a few of the bugs slip through. A good indicator of that is when you boot your laptop do you see anything on the screen at all? When your booting the O/S runs your grpahics as vanilla display until your actual driver is loaded. If at all possible, and if you have a copy of your O/S's install cd, try and boot from that cd. If you still can't see anything, then you could pretty much be assured that your graphics unit has died on you. The fact that you couldn't see anything on an external monitor probably bears that out.

Try the reseat, try and boot from your O/S's install cd. If everything fails it would be a good indicator that your graphics unit has given up the ghost.
