Ifthe laptop battery is more than 3 - 4 years old then the battery could be wornout. Rechargeable batteries have a finite number of charge and discharge cyclesand will lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up at all. ORThe battery shows a 100% charge but when the adapter is disconnected thebattery drops off to zero capacity in a very short time. Ifthe battery drops to an unacceptable charge level then the battery needs to bereplaced. 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.

Will not start


Hello,

It sounds like the DC charging port on the laptop may be damaged, or it may be the power cord...here's how to tell:

First thing....remove the laptop battery, click the battery back onto the laptop and try again. If this doesn't help then read on...

When you put the laptop on the dock, it is getting it's power from the dock connector on the bottom of the laptop. When it is not on the dock, it gets power from your DC adapter. Soooo......take the laptop off the dock and plug the DC adapter into the laptop. Do you see ANY led's light up (on the laptop) when you plug the power cord directly into the laptop? If not, then your DC power adapter for the laptop is probably dead. If you DO see any led's light up when you plug the power cord directly into the laptop but the power button won't turn the laptop on, then the power button on the laptop is the problem.

Take your laptop to an electronics store, and see if they have any universal power adapters for laptops (they come with tips to fit all major laptop brands). Test your laptop at the store with their new power adapter. If this fixes it, then buy the adapter. If this does not fix it, then you should take it to a reputable service shop to get the power button repaired or replaced......or call HP if your laptop is still in warranty.

Hope this helps!

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.

My hp laptop won't power up. I bought a new power cord and connected to my laptop and the power light won't come on, so what esle can i do to get power to my laptop?


Have you followed the Guided Troubleshooting steps provided on the HP Support web site?

These will take you through a series of checks and decisions to try to isolate the cause of the problem along the following lines:

1. Are you sure you are plugged in to a good power outlet - can you plug a lamp in and does it work?

2. Are you sure that you are using the right power adapter for this laptop, is it the original HP block supplied with the laptop or is it a replacement - if the latter, then does it supply the correct output voltage and watts required by the laptop.

3. Are you sure the problem is not just the laptop display being dead, i.e. have you tried attaching an external display, do you get any leds light on the laptop for power, disk activity etc?

4. Have you tried removing the battery from the laptop and connecting the power adapter with it removed to prove that the battery is not preventing the laptop from powering on?

5. Have you disconnected all external devices from the laptop, in particular docking station, printers, USB devices etc to ensure that no external device is preventing it from powering on?

6. Do you have another power adapter that you can try using - are there any lights on the power adapter to show that it is working?

Dell Inspiron 6000 powers up, caps lock flashes 9 times, then laptop shut down. Why???


Unplug power cord from laptop, remove battery from laptop. Open memory access panel on the bottom of the laptop. Remove memory module(s) (SO-DIMM). Plug power cord back into laptop. Turn laptop on (with the memory removed), the caps lock and scroll lock LEDs light, then the laptop shuts itself off. Unplug power cord from the laptop. Reinstall the memory modules. Make sure they are seated correctly. Put the battery back in, plug the laptop back in, and power on. Laptop should power on and boot up properly.
May need to hold the power button down to get it to power on properly.

Gateway kav60 not charging. i have to wiggle the cord and sometimes it refuses to charge.


I guess you've got a broken laptop power dc jack or power cable.


Symptoms of a broken Laptop DC power jack:


- The laptop only operates when you hold the DC power plug in a certain direction (DC jack is broken or loose).
- The laptop only runs on battery power (no power is getting through the DC jack).
- The laptop gets no power at all.
- The laptop will not charge the battery.
- The laptop switches from AC power to battery power intermittently due to a loose or broken power jack.
- The laptop suddenly shuts off.
- The DC jack may feel loose.
- Sparks come out of the back of the laptop when you insert the power plug into the DC jack.

  2. Remove the battery from the laptop
  3. press and hold the power button on the laptop for about 30 seconds
  4. Insert the battery back in to the laptop
  5. connect the power cord to the laptop
  6. Try to start the laptop normally by briefly pressing the power button.
Good luck

Compaq presario M2000 power cord won't charge my laptop


Check that your power adapter is working fine it may be that the power cable is broken somewhere between the adapter and the laptop. You could try another charger / adapter.
