The power-up starts, fan runs for about 1 second and then shuts down. I have taken out the memory, HD, battery and reseated them. I found something on another site about opening up the LCD video display to see if the connectors are all seated. Seems a loose connector gave the same set of symptoms. It was discovered by hooking up an external monitor. Laptop worked fine with monitor (video cable was disconnected from board). How do I go about opening up the LCD display?

is this happening everytime you start the machine? What is being displayed on the screen? Do you hear the fans running when you press the power button? Do you hear the disc drive running? Do you hear the cd drive click once and the light on the cd drive door come on for a second or two? Is it posting anything on the screen during the boot process? Is it getting to the actual windows desktop which is where you see your icons? Computers shut down for a reason. Either some piece of hardware is not working such as a fan, or some hardware is faulty (such as the memory, cpu or motherboard), or some software issue or a virus has taken over.
Try this unplug plug the power cord and remove the battery and hold the power button for 45 seconds,Then reinstall the battery and and try to start the computer,
if it fails to start unplug plug the power cord and remove the battery and hold the power button for 45 seconds and remove the memory and any usb devices that may be plugged in,then start it,
If it starts
Allow it to load completely and then shut it down and install one memory stick and restart, if all is well after if loads completely, shut down again and install the other memory stick and restart, if all is well again wait until it loads completely and then plug in and allow to load each of the usb devices you may have
1. Unplug the power from the laptop and remove the battery then press the power button of the laptop for 15 seconds
2. Put the battery back in, turn on the laptop without plugging the power to the laptop (If this didn't resolve the issue)
3. Remove the battery and press the power button of the laptop for 15 seconds, after that, plug the power cord and turn on the laptop (if this didn't resolve the issue)
4. Remove the power cord and press the power button of the laptop for 15 seconds, disconnect the Hard drive and turn on the laptop (If this didn't resolve the issue) reconnec the hard drive
5. Remove the Optical Drive and turn on the laptop (If this didn't resolve the issue) reconnect the optical drive
6. Remove the memory chip, if you have 2 memory chips installed in the 2 memory slots (remove both of them) now test each one of the memory to each slots turning on the laptop. (If this didn't resolve the issue) Put the memory chip back in
7. Reseat the CPU and try to make sure that it's installed properly. Turn on the laptop and test if it's gonna work (If this didn't resolve the issue)
8. Reseat the power cords coming from the power supply of the laptop and test the laptop. (If this didn't resolve the issue)
9. Disconnect everything and just leave the CPU installed and turn on the laptop.
10. If all else fails, there's a big possibility that the problem may be with the power supply or the motherboard of the laptop.
(Note: you may try to clean your computer if there is a large amount of dust. You may try to remove the CMOS battery)
Try reseating the RAM memory modules, see if any change.
If no change, remove, battery, Drives, Wireless card and RAM, see if the system will run longer or give an error code. If something changes, add 1 RAM module and try again. If the system runs, then add items back one at a time until you determine the faulty item.
If the system issue doesn't change, odds are a motherboard problem. Motherboard are about $100 on Ebay
Remove the main battery and power the laptop up - if it works connect the battery - no need to shutdown.
Next thing to try.
Remove the main battery and the BIOS battery wait 1/2 + hour, insert BIOS battery but not main battery - power up, configure BIOS Date & Time setting if OK connect main battery.
If none of this work, you have a large paper weight.
You can salvage the hard disk and insert it into an USB hard drive adapter case and use it as an external USB hard drive.
sounds as if the laptops in hibernation or sleep mode.
Try refering to the user manual regarding the mentioned points.
also try alternating the memory from slot to slot, 1 faulty slot or ram module, will cause the computer not to boot.
Finally, if this is a model that has a ribbon-cable from power switch, to motherboard. ensure it,s inserted correctly/square et,c.
If it's not beeping during the first start up then it's not POSTing. Beep means everything connected to it seems to be functional ie PnP
Try pulling out your memory and reseating it.
Try pulling out your battery for 5 minutes then plug in ac(without batt) and see if it will boot.
Try pulling your hard drive and reseat. (access by covers on bottom...dont be scared. Touch something that's grounded just before you remove)
If all this and still no full POST(with beep/s) then sounds like a new mobo or processor.
