Laptop booting up and then shutting off unexpectedly.
I have a Gateway laptop that was started this morning and unexpectedly shut off. Now, I can't start it. Lights come on and immediately shut off. Interestingly enough, an older laptop I had sitting around I decided to bot up in the meantime started to give problems now, too. It boots to Windows everytime but shuts off unexpectedly.

Re: Laptop booting up and then shutting off unexpectedly.
This sounds like the cpu fan assembly go to Gateway and enter the model in the support then download the system diagram so you can remove the casing it would take me forever to type the inst. once you have removed the cover put you hand over the cpu fan assembly and check for airflow

Computer does not boot up The problem maybe the RAM, it is faulty or just needs reseating to make proper electrical contact. Reseat the RAM and then boot up your laptop. If it still does not boot up then remove the RAM module/s and take them to your friendly computer repair shop and get them to test the RAM for you. Just like you sometimes need a mechanic to repair your car, sometimes you do need a technician to diagnose and identify the fault or faults on your computer. Not only does a good service technican have the experience to deal with this type of problem, they also have the equipment that allows them to look at things the average computer user can't see, and he has a collection of replacement parts that can be used to quickly test individual components on your computer.
The CCFL or it's power supply have failed. (Cold Cathode FLourescent)
To verify it, hold a flashlight close to the screen and see if you can see the screens change as it boots up.- if so- start with the CCFL. The good news at least on most you only need to dismantle the upper portion of the laptop. If you have one salvaged from something else like a scanner, you can usually at least test the CCFl supply to make sure it is functional by plugging the spare in where the original was plugged in and boot up- if the tube lights right away, shut it down and let it discharge of electricity as the circuit will hold a charge for part of a minute.
To reach the CCFL, you will need to remove the display from the plastic, and will see where 2 heavier looking wires attach to a small PC board- these are the CCFL leads. It is fragile, you will need to remove the metal frame, and you may need to lift the display and difussion layers from the surrounding plastic to adequately expose the CCFL for removal and clearance for the replacement. Reassembly is jsut the reverse order of disasembly.
This is a tricky issue, it's either a problem related to the battery or the adaptor.
Try removing the battery and just plug in the adaptor and see if the computer will boot. If it does then there's a problem with the battery and you just need to replace it, if it doesn't then there's a few other things it could be.
The two most likely options is that the adaptor is bad, or the AC port on the computer has become loose. Most of the computers I've repaired that had these symptoms was that the AC port was bad if the battery wasn't. The best way to test this is to plug in the adaptor and just see if it wiggles around a lot, if it's loose then it might not be connecting to the board correctly and will need to be soldered bad on. If it's not loose then the adaptor might be bad, you can test another adaptor on your laptop or that adaptor on someone else's but be carefull, I can't stress this enough, if you're going to switch adaptors you have to make sure that the voltage IS EXACTLY THE SAME and has the same amps, if the voltage is off you can damage the computer, if the amps is off you can damage the adaptor.
If by some fluke it doesn't seem to be the battery, and you tested the adaptor and the AC port doesn't feel loose, then the charging circuit in the laptop might be shot, in which case you'll need a new motherboard.
I think that covers everything, sorry for the wall of text
First thing check that the battery charge light is on when the battery and the charger are connected.
If it is it indicates that the power supply is charging the battery,
If it isnt it may indicate a fault with the battery or that the charger is not compatable with the laptop or that there is a fault with the charger.
If the battery is charging then try running the laptop on battery only without the charger and on charger only without the battery.
This will eliminate which one is faulty.
You mentioned that if you wiggle the cord then the light comes on again.
Check to see if the charger end plug is lose or the actual port on the laptop is lose.
If the charger plug is lose then return to seller and make sure they gave you the correct charger. if the actual port on laptop is lose then perhaps u got a bad connection and you need electrician or local laptop technician to open it up and solder properly on motherboard.
Hi there. The battery maybe faulty, remove the battery and try it on AC power only, there are no fuses that can be replaced inside the laptop. If the laptop boots up on AC turn it back off and reinsert the battery and try to boot again, if it does not boot up then there is a problem with the battery and you will need a new one.
Maybe a heat issue. I had a P4 system once that would do that exact same thing. I cleaned the cpu cooler and fans and added new heat sink paste between the heat sink and cpu. No problems after that. Let me know if this helps.
