Hi

Try to remove the battery, hold on power button for about 50-60seconds, then plug-in the charger and turn the laptop ON, see what happens.
If it was OK, then plug-in the battery and try to start your laptop.
If it was OK, Congratulations.
If not, so it's bad news, the battery is dead.

Please tell us your results
Good Luck

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. This can be repaired but itrequires the laptop to be completely dismantled to get at this power socket andrepair. If you cannot DIY then I suggest you get a quote first.

My hp pavilion dv6-2117ax laptop won't power up (no power light on where adaptor meets laptop). Replaced power adaptor / charger and laptop powered up and operated for a day and then next day woul


The laptop probably isn't charging. Could be a bad d/c connector on the laptop or the battery is bad. Remove the battery and plug in the a/c adapter and see if it powers on. Wiggle the a/c plug in gently while pressing the power button on the laptop. It powers on and off briefly then I'd say it's the d/c jack on the laptop, bad sodder joint.

Compaq M2000 turns on using charged laptop battery but doesn't charge or turn on when using power adaptor, with or without the laptop battery


1) The AC adapter should ALWAYS be plugged into the laptop FIRST, then plugged into AC power. If not, this could create a voltage spike.

2) Let's look at the DC Power Jack, for the Compaq Presario M2000 series of Notebook PC's,

http://www.notebookparts.com/products/description.php?II=9741

The DC Power Jack is mounted to a removable circuit board.
Enlarging the view of the jack, shows us there is an Inductor.

The small 'can' standing up on the power board. This chipset could have gone south. (Bad)

How to know? Replace it, or dig out your dual trace oscilloscope. See if the Inductor works.

Could also just be cracked solder joints, of the DC Power Jack, TO that small circuit board. Solution would be to resolder it/them.

[ I WOULD however, search for a BETTER price, than listed in the link above, IF available ]

DC Power Jack is in good shape, soldered tight to the motherboard, and ruled out as the problem?
(Since you know the AC adapter is good)

Then the problem would be the Inductor on that power board, or power correcting chipset.

What one is it? Dunno.
DO KNOW is has J leads on the bottom.
CAN give examples, and perhaps you can identify using them.

My 1501 Dell Inspiron turns on but I have a blank black screen. The only light that shows is the power light on the upper right side of the laptop.


Power getting to the laptop. Try first to see if this will give a screen image on an external monitor, listen for the sound of the cpu fan, hard drive and DVD rom drives clicking, see if the DVD rom drive will open if pressed.

Then remove battery and AC adaptor, press the power button for 30 secs, refit mains only and try this on mains supply (no battery)

If this fails to boot, check the light on the ac adaptor is a steady green, flashing green indicates power is not fully reaching the laptop (motherboard problems)

If it is steady and the LED power light on the laptop is steady, suspect the DC jack socket. If this feels loose or sloppy, it will need replacing, depending on the type fitted, it may be soldered onto the board, or a wired connector, which sometimes goes bad.

After that, I'd suggest that a capacitor has gone on the actual motherboard and you will need to strip the laptop to check it.

I typed in my computer and then all of a sudden my screen went blank. I tried to turn on the power button, but I don't get any connection. What could be the problem?


try to remove the battery pack then insert the power supply adaptor and power it on,the battery might freezing the supply and no more supply entering on it all thru pc because some shortage takes place.

try to hold the power for several seconds and plug in the power supply adaptor,release it when it powers on.



Good luck

Laptop will not power up.


  • If possible, make sure there is power coming from the power adaptor with a voltmeter. If nothing shows, the adaptor needs replacing or repairing.
  • Try removing the battery and running on the power adaptor alone. If this works the battery is dead. You can buy a new battery or just run it on the adaptor.

Power Problem with A/C adaptor on my Gateway M-6816. The light on the a/c adaptor flashes green and the laptop wont charge. This is a new factory a/c cord.


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.

Power light shuts off after only 3 seconds


Disconnect the AC adaptor from the laptop and remove the Battery pack from the Battery bay. Then, remove the RAM module and reinstall it after cleaning the RAM slot. Next, connect the AC adaptor to the laptop then try turning it ON. Please make sure that the AC adaptor is connected to a functional wall outlet. If the laptop still doesn't turn ON then you may try cleaning the Battery bay and the metal contacts in the battery compartment then insert the battery and try turning ON the laptop. If the laptop still doesn't turn ON then the issue is with the power supply unit.
