SOURCE: Laptop won't power up dies in the middle of movie-won't power up

You would probably be better off buying a new notebook. Not sure how tecnologically advanced you are but it seems you already did the troubleshooting yourself. But i am very interested in the a/c adaptor output. If the led on the adaptor is green that just means that it is getting power from the wall.

What did you mean by fluid leaking out?

It could be the mobo (motherboard) or it could be the connections from the power to the machine. If you want to put a new mobo in I have to warn you that taking apart a laptop is VERY difficult and I do not recommend this unless you are a PRO. This is just about the only link i can find to buy a new board. If you google your laptop model you will find out you definately are not alone with this problem

SOURCE: sony viao wont boot, battery light flashes amber

Move the power jack around while plugged in, does the blinking on the battery stop when you hold it in certain positions? If so, your dc-jack needs to be soldered, but i probably was loose already before you started using it. It could be a broken motherboard issue as well. You can try to open the laptop and check the dc connection. There is a Laptop Repair Guide that shows you how to take apart a laptop, the sony may be made in a similar way. Sony Repair NYC

SOURCE: I own an Acer Aspire 1800.When turn on with its

I own a Acer 1800, I have fixed it many time. Each time it beep and flash power button it mean the charger adapter is not giving a constant 19V voltage.
I also saw that you unplug the charger and test and there you have 19V. The answer is, sometime when there is no charge the adapter can provide 19V, but this laptop need 7.9 amp to work so when a charge is apply to the charger voltage drop and shutdown.
Most of the time I found myself opening the charger and sodering back capacitor. whatch for what we call a cold weld.
It is a place where arround a leg of an electronic part the soldering is gone or has a small round shape crack. those are cold joint.
if you don't feel like fixing your adapter, then whatch on ebay there is some to be sold. I found them to be cheap.
Whatch for the correct voltage and amperage otherwise your computer won't work correctly.

SOURCE: Hellow Dear, My acer aspire 4935

First, you need to make sure your power adapter is providing enough power to both run the laptop & charge the battery. A very good way to do this is to compare your laptop voltage & ampere requirements (written on a sticker on the bottom of the laptop) with the voltage & ampere ratings of the power adapter. Voltages should be the same, or the power adapter's voltage about up to 0.5 volts more than the laptop's voltage rating. Amperage of the power adapter should be at least equal to or greater than the laptop's rating. It should never be less than the laptop's rating, or else the power adapter will be providing insufficient amperes to charge the battery. Of course, the power adapter's nominal amperage might be ok, but it degraded on usage. You can verify this by testing using a good or new power adapter.
If the battery did not charge using the new power adapter, take the battery off the laptop, & using a dry tooth brush, scrub in between the fins of the battery connector on the motherboard & on the battery it self, then put the battery back into the laptop & try again.
If this still did not resolve the problem, then the battery itself could be bad. Try it on another laptop, or try a good or new battery in your laptop.
If this did not work, there might be a possibility that the charging circuitry on the laptop's motherboard is defective & needs servicing. In order to do this, the laptop needs to be disassembled & the motherboard checked for defective/burned out components in the area near the DC jack. Any defective/burned out components found should be replaced, or you might need to replace the laptop's motherboard altogether.

Dim green light on power supply blinking


If the Power supply LED dims and flickers its either your motherboard circuit has been cut or there is a short in the laptop. The AC adapter is not the cause.

Try this:
Remove the battery, then press power button to drain all the current, then re-install battery and plug to adapter.

If that doesn't work, then it's most likely the motherboard.

My samsung laptop will not turn on. How do I fix this?


Hi

Possible reasons why your laptop doesn't boot ( Power on with green light indicator lit)

-battery problem
-memory problem
-power failure
-etc ( maybe one of the hardware that is connected inside your laptop)

Troubleshooting steps:

1. First you need to try switching on your laptop without the battery
Basically you will remove the battery of your laptop and connect the ac power then switch it on.

a. If your laptop boot up ( with a green light indicator ) the problem will be the battery.
b. If the laptop does not boot up continue using step 2.

2. Unplug the power adapter , remove the battery and memory
Watch this video and it will help you to remove the memory
http://www.youtube.com/watch?v=kdDf46XKXiE&feature=related
NOTE: Your not going to upgrade your memory!

After removing the memory put it back close the panel and put back the screw.

Now after putting the memory , Try to plug the ac adapter and press the power button and check if your laptop will boot ( No need to put back the battery because your laptop will power up with out the battery )

If your laptop will still have the same problem the best thing to do is to bring it on the nearest support center for Samsung laptop because there's a possibility the problem will be the hardware that is connected inside your laptop.

I want to provide you the complete information on how to open your laptop however since your just new with this and to avoid any damages the best thing that you can do is to bring it on laptop specialist if the troubleshooting steps that I provided will not work.

Be careful Alright! Good luck
Have a nice day

I tried to power on my computer and there was nothing. It was plugged in and the battery light was blinking amber when I tried to press the power button. The light on the power cord is green but there is...


It sounds like the Power adapter is:

1. Not plugged into the computer
2. Not functioning
3. Has a broken connector (or the laptop has a broken power connector)

Unplug the adapter, remove the battery, hold the power button on the laptop for 30 seconds. Plug in the power adapter connector to the laptop - if the power indicator illuminates, remove the power cord, insert the battery ant then plug in the power cord. Press the power button (hopefully you're back in business).

If that does not help, p borrow an adapter from a friend and try it with your laptop, if it works, then go buy a new adapter!

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

Not charging


which green light?

light from the ac power adapter or the light from the battery?

if ac power adapter you are referring to try a diff power wall socket if ac power adapter still off then replace ac power adapter alone.

if battery light is off but the laptop works fine with ac adapter alone try updating the laptop BIOS.

if ac adapter light turns off when it plug to the laptop replace motherboard.

Your motherboard is probably shorting out your A/C adapter, you may need a new motherboard.

Sony Vaio ac adapter submerged


If the ac adapter was plugged into the laptop at the time may be bad news. Unplug AC adapter, take out the battery and hold power button for 10 seconds. Then connect AC adapter and hit power. If that doesn't work put battery back in without ac adapter and hit power button.

If neither test works bring to repair center for diagnosis. Best case AC adapter would need replacing. Worst case Motherboard fried.

Thanks
