Amilo m 3438g laptop will not power up

Is the battery connected? If so, remove the battery and try powering up just on mains power. This may then start okay.

Whenyou connect the power adapter into the laptop, does the power LED lightup? If not then - The battery adapter or the adapter's power lead or the laptop's powersocket could be faulty. Check power adapter's DCplug that connects into the laptop power socket with a multi-meter, the voltageshould be slightly higher than the voltage that is printed on the label on thebottom of the adapter. If the voltage is zero or way below the voltage that isprinted on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK thenconnect it to the laptop and power it up, then look at the power/batterycharging LED light and wriggle the power plug in the laptop's powersocket. If the power/battery LED light flashes and in a certain position thisLED light stays firm, then the power socket is either faulty or it has a drysolder joint where it is connected to the motherboard.

Remove your battery and make sure that the battery voltage on it corresponds to the reading on your multimeter. If not replace and plug in the adapter/charger Now check the voltage at the battery terminals. If present then insert battery and allow the battery to fully charge as indicated on the LED. If the laptop does not work with the adapter plugged on, then the fault can be in the mother board section, possible areas can be the power supply, regulator and processor.

If the battery is fine, then the only other power source is the power adapter cord. You'll have to borrow/buy one and make sure the wattage which is on the square part of the adapter matches...if you have any questions let me know..

boot up your laptop and take a magnet in your hand and revolve around the screen the screen might go crazy but all the colors will be back in a while. :)

If you have a spare ac adapter, try that just to check if it's the ac adapter.

When you power it on, are there any lights on the notebook?
If there are lights, it is indicating that the computer is receiving power but is not able to go through POST ( power on self test ) and normally it's the mainboard that has the problem.

Either way, if there's no lights, it is also the mainboard that is the main cause.

The notebook will have to be sent in for repairs or just replace the motherboard.

Try powering from the mains and see if your battery is being fully charged.

although I never tried it, I dont think you can operate a laptop with no battery, even when its connected to AC.

Please whe you change the battery and it does not solve the problem try replacing the "brick" probably the "brick" is not doing its job properly.

It maybe the problem of your laptop ac adapter,find a new universal laptop ac adapter to have a try.
