1. Take the battery out of the laptop & try to turn on the laptop using power adapter only. If the computer turns on, then the battery is defective & needs to be replaced.
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. Make sure the DC jack is not loose or broken. A loose DC jack will need to be re-soldered. A broken one will need to be replaced.
4. If you have another processor which is compatible with your laptop's model, try swapping processors & test to see if the laptop will work.
5. The power button could be bad.
6. The motherboard could be defective & needs to be replaced.

Why won't my computer boot up?


does not sound easy . Try holding power button in for 30 seconds and then try normal power up. Is the AC adapter plugged into laptop it may have a flat battery. If the Ac to DC adapter is failing to charge the battery this could cause a flat laptop battery and cause the symptoms you are experiencing.

My Asus Laptop won't turn back on, there is a chemical smell, and my adaptor green light brinks


Here below are possible causes and troubleshooting steps of laptop that can't power on, hope it may help:
Possible causes:

1. AC adapter failure.
2. Power jack failure.
3. Motherboard failure.

Possible troubleshooting steps and repair solutions:
1. Test the Acer Aspire 5920 ac adapter with a digital multimeter. It's possible that you have a failed AC adapter. If you don't have a multimeter, test your laptop with another known good AC adapter.

2.It's possible that power jack (socket where you plug the AC adapter) is broken. Remove the motherboard and take a closer look at the power jack. In some cases you can fix the jack by resoldering it on the motherboard. In other cases you have to replace the jack with a new one. Using a multimeter, test if the power goes to the motherboard through the jack.

3. If replacing the AC power adapter and jack on the motherboard doesn't help, most likely you have a bad motherboard. Replace the motherboard.

Asus wont turn on


For this kind of issue, please follow up the following steps to check:

1.confirm the battery and ac adapter connect the laptop normally.Maybe the bad connect lead to this problem. If there are no lights when you turn on laptop, one of possible reason is that your adapter is malfunction.

2.the second possible cause is laptop dc jack failure. If the dc jack is broken or loose, you are required to replace it or repair it.

3.Another possible reason is that there is something wrong with laptop motherboard. For this situation, it includs two kinds of possibility,a failure in an electronic circuit and BGA malfunction.

For more detailed reasons and solutions, please have a look at the following article:http://www.ifitjams.com/lappower.htm

If you verify your laptop adapter is dead and you plan to order a new one, I recommend one for you on the basis of your laptop model:

Recently, the battery of my vaio died, but I could still manage by getting the power from outside sourse. However, I couldn't even turn it on last night, even though the vaio was still getting the power...


eventhough the light indicator on the ac adapter is still working, it doesnt mean that the ac adapter is still working fine..

  • the problem could be the ac adaptor itself, the dc in port of the computer or maybe the motherboard.
if the computer is still in the warranty, sony will cover the battery, ac adapter replacement, or process repair if needed. you can call them at 888 476 6972 or 239 768 7669

When I plug in my ac adapter into my computer to charge it the green light turns off and won't charge my computer


The diagnostic procedures from the Dell User Guide are as follows:

Total Power Failure When Using a Battery
If an AC adapter is not connected to your computer, the computer's power source
is a battery. If the battery indicator flashes amber or is a steady amber, the
battery needs to be charged. If the battery is flashing green and amber, the
battery may be defective. To troubleshoot this problem, use the following
procedure.
1. Turn off the computer and peripherals, and disconnect them from AC power.
2. Reseat each installed battery by removing it and then replacing it.
3. Turn on the computer. Does the green power indicator light up?
Allow one minute for the computer to initialize its components before checking
for signs of power.
Yes. Continue to step 4.
No. Use the AC adapter to connect your computer to AC power. If the computer
operates normally when using AC power, go to step 7. If the computer does not
boot when using the AC adapter, see the previous subsection, "Total Power
Failure When Using the AC Adapter."
4. Does the battery indicator flash amber or show a a steady amber light?
Yes. The battery needs to be charged. Go step 5.
No. Go to step 7.
5. Connect the computer to AC power, and fully charge the battery.
For instructions, see the topic titled "Charging the Battery" in the online
System User's Guide.
6. As the battery charges, does the green battery indicator light up?
Yes. Go to step 9.
No. Go to step 7.
7. Is the battery indicator flashing green and amber?
Yes. Your computer may be in a hot environment. Charging the battery in this
condition may affect the life span of the battery. Continue to step 8.
No. The problem is resolved.
8. Disconnect the computer from AC power. Is the the battery indicator still
flashing amber?
Yes. You may have a defective battery. Continue to step 9.
No. The problem is resolved.
9. Remove the battery, and press its test button. Is the uppermost indicator in
the charge gauge of the battery flashing?
Yes. You have a defective battery. Continue to step 9.
No. The problem is resolved.
10. If a spare battery is available, fully charge it, and then install it in the
computer.
11. Turn on the computer. Is the power indicator off?
Yes. Your original battery is defective


good luck
