That typically indicates a powersuplly malfunction (not providing enough power) or, more likely, a motherboard issue.

The best way to rule out the first part, which is the easiest, is take it to a local repair shop or radioshack and see if you can borrow a power supply to test. Make sure it is the same voltage and similar amperage. This information can be found on either the bottom of the power supply brick or the bottom of the laptop itself. Something like "19V 4.3Ah" which means 19 volts DC at 4.3 amp-hours, or amps. Amps are not important at this stage just for quick testing. Using a power supply with too few amps could burn out the power supply exceptionally quick.

Most of the time you can get replacement motherboards on eBay for cheap. The down side to this is that laptop motherboard replacement is far from fun. From experience, I tend to avoid repairing laptops due to that fact. You could be exceptionally lucky and have a special, seperate, power board inside the laptop. This is not common and not likely. It is most likely connected directly to the motherboard.

If it is truely the motherboard and you found a cheap replacement, the cost of professional installation could warrant the cost of a new laptop. You could always compensate for the price of a new laptop by selling your current one "as-is" on eBay.

If you do dispose of your laptop, you can always pull the data off the hard drive. Easier than it sounds unless whatever caused the motherboard to fail caused the hard drive to fail as well. A simple 2.5" laptop hard drive to USB adapter can be found for mere dollars and allow you to plug your laptop hard drive in and copy the data off it. I carry a 30gb laptop hard drive in a usb encloser with me all the time.

Hope this helps!

Not good..sounds like either the power supply has not enough juice, or the mother board is unhappy..check the power supply for proper voltage as indicated on bottom of the power supply..

My gateway m460e wont charge or turn on there are no lights the mother board is dead.what cause this?

Assuming the charger is ok and the battery is ok, you may have a main motherboard fuse which has blown (would explain the lack of power), if the fuse is not the issue, then it looks like there are other damaged components on the board

Computer wont power on although both lights come on and battery is charged

1. Take the battery out of the laptop & try to turn on the laptop using power adapter only.
2. Make sure the power adapter is not defective. Test the output voltage of the power adapter using a voltmeter. Compare the voltmeter reading to the nominal value written on the adapter or the laptop.
3. If you have another processor which is compatible with your laptop's model, try swapping processors & test to see if the laptop will work.
4. The power button could be bad

Hi. Try theses simple steps:

Remove the Battery
Remove the AC Adapter
Press/hold down power button for 10 seconds
Plug AC Adapter in and turn the computer on
If the system doesn't turn on still then there's a problem with your motherboard. and it might need replacement.

I left my laptop turned on in my office when i came back then next morning it wont start even if I push the power button. The laptop was turned on when i left it.

Try to perform power drain. Take out the battery and unplug the power adapter. Press and hold the power button for 30secs. Put the battery back in then plugin the power adapter then trn on the computer. You can also power on the computer without the battery. If your computer wont turn just using the power adapter then there is a possiblility that there is a problem with your power adapter.

There could be a problem with the battery. A fast check to determine whether you have a problem with the power adapter, power cord or the laptop's battery is to turn off the laptop, remove the battery, connect the power adapter, turn on the laptop & see if it works.
If the laptop works directly from the power adapter with the battery removed, then the power adapter is good. In this case we can suspect that the battery is defective & needs to be replaced.

My inspiron laptop wont turn on after I replaced

Verify that you obtained an exact replacement power adapter for the Dell. If it is an exact replacement then try this. Disconnect power adapter. Remove battery. Reconnect power adapter without the battery. If it turns on, then power off and place battery back in. Then try again. If problem returns, there could be a problem with the battery itself.

Password on boot up

This usually works with a bunch of motherboards,

1. Open the CPU.
2. Unplug it from the power.
3. Remove the BIOS Battery.
4. Press Power without pluging it in a power supply.
5. (IF you can) Try and find a pin usually 3 of them with a jumper connecting 2 of them (middle and 1side) remove it and connect the middle and the opposite side and press power on again without plugging it.
(IF you can't find it) Just push the power button for about 30 seconds without pluging it.

Vote if it helps thanks
