Hello.The most common reasons for power issues are the battery, power jack and power adapter/cord.Power off and remove the battery. If the laptop powers on with just your hp probook 4730s adapter connected, your battery is faulty.If you move/wiggle the power adapter at the point where it connects to the laptop, and the power goes off and on, the power jack is the problem.The power jack is inside the laptop and either needs soldering or replacement. If a power jack problem, it should be addressed by someone knowledgeable.If no change, the power adapter is probably faulty and needs replacement.Hope this helps.

SOURCE: dv9000 won't power on or charge. blue lightning bolt flashes

I just had this problem with my HP Pavilion dv9005us Notebook PC, and the problem is one of two things (that I know).

  1. Your'e Laptop's battery is completely empty, and needs to be plugged in to charge for an hour or two
  2. Or your laptop cord is broken, or isn't working properly.
For me, it was the secon problem. I went online searching for answers as to where I could buy a new cord for my Laptop. My previous one was universal, as the one that came with the notbook was chewed by my puppy. So Staples Canada, (or US) and Futureshop where the only places I could but this cord. They had the laptops on one wall, and the cords underneath them. In total, I paid $112.00, $89.99 plus tax, and $10 for an extended 2 year unlimited warranty. It sucked forking out the money, but I knew that I could trust the HP brand, and now have a working laptop.

Hope this helped (:

SOURCE: HP Pavillion dv6000 -when I plug in AC adaptor, it won't charge

Hi ja525,
If you have tested the power adaptor with a multi-meter to confirm it is OK or the other adaptor is also OK assuming that it is the correct voltage and at least the same current rating. Then the fault is most likely the power connector in the laptop.
To confirm this, power up as normal with the power adaptor connected and switched on, when the blue LED dims wriggle the power connector where it connects into the laptop and if the LED comes on or blinks, that means that you have a faulty power connector, it couls be a dry solder joint at the power connector.
It is possible that the power adaptor is shutting down (thermal overload) due to insufficient current capacity, Check the Amp rating of the laptop, it is usually on the lable on the botom of the laptop and check it against the power adaptor, the adaptor should be equal too or greater that the laptop's current rating.

To fix a faulty connector, you can dismantle the laptop and with a fine tip temperature controlled soldering iron, resolder the power connector and hopefully this will fix your prolem.

Laptop won't switch on although blue power light on is showing power is getting to the machine


Check the power adaptor led is not flashing. Flashing Adaptor LED indicates fault with laptop charging circuit / powerboard

If it will not boot on battery, and you know the adaptor to be good, the issue lies with the motherboard.
Sometimes, removing the battery, and unplugging, pressing the power button and holding it for 30 secs, replacing the adaptor only will allow it to boot up, but this will only work if the motherboard is not damaged r the CPU fan has not failed.

Battery light flashes orange three times then green. It doesn't impact battery life or operation. Is there a danger I that I might lose all my data? can I safely continue using laptop with ac adaptor...


This indicates either a faulty battery, charging circuit or motherboard issue with the charging port or charging circuit.

You can run the laptop solely on the ac adapter without issue as long as you have steady power. Try removing the battery and plug in the AC adapter and see if the laptop gives you the same light flashes...if it does, you maybe having an AC adapter issue. Try running the laptop solely on the battery and see how long the charge lasts.

Hopefully, all you are dealing with is a battery that is losing a few cells but is still capable of functioning...then you just have to get a new one.

Dell 9400 wont show AC power icon


If the computer is connected to an electrical outlet, the about10.jpg light operates as follows:
  • Solid green: The battery is charging.

  • Flashing green: The battery is almost fully charged.

If the computer is running on a battery, the about41.jpg light operates as follows:
  • Off: The battery is adequately charged (or the computer is turned off).

  • Flashing orange: The battery charge is low.

  • Solid orange: The battery charge is critically low.
Looks like the AC adaptor is faulty.

Ac adapter will not charge my computer


If the laptop will run from the adaptor, then the adaptor is probably fine. That being the case, if the charge light flashes when the adaptor is plugged in, the battery is faulty. No charge light on an otherwise working system is probably the battery charging circuit in the laptop.

Wont turn on


Hi,

you have one of 3 things wrong here.

1:) the battery is dead, and needs to be replaced ( suggest e-bay china seller for cheapest )
2:) the AC adaptor or dc socket on the motherboard is Faulty.
3:) motherboard fault, regarding charging circuit board.

Go for the most cost effective option First. New Battery. Then AC Adaptor. Finally would be motherboard replacement.

Battery and or charger


Try removing the battery and see if the laptop works with the AC adaptor. If not either the AC adaptor is bad or the motherboard is defective.
If your battery LED flashes (yellow or Amber) or is solid Yellow or Amber color, this usually indicates battery is beginning to go bad. Eventually it will not hold a charge and will need to be replaced.
As for the error message “failed DST short test 1000-0146”, this is flagging an error on your hard disk drive. This could be caused by a bad hard drive or just needs to be reformatted.

Lap top problem


Hi

If the AC power light is blinking, try the following steps:

1 Cut off power to the computer by disconnecting the AC adaptor and removing the battery. The error condition will be interrupted, and the AC power light will stop flashing.

2 Put the battery back into the computer. Do not connect the AC adaptor. Try turning the computer on again. If the computer starts normally, the AC adaptor may be
defective and will need to be replaced. If the AC power light starts flashing, remove the battery, and continue with the steps below.

3 Connect the AC adaptor to the computer. Leave the battery out of the computer. Try turning the computer on again. If the computer starts normally, the battery may need charging, may be depleted, or may be defective. Turn the computer on, insert the battery, and then leave the computer running for several hours, which will deliver a slow, steady “trickle-charge” to the battery. Once the battery has been trickle-charged, it may begin working correctly again. If the trickle-charging does not prove effective, consider replacing the battery with a new one.

4 Connect the AC adaptor to a different power outlet, preferably in a different room. If the computer starts normally, there may be a problem with the AC outlet itself, or the voltage level available from it.

5 Verify that the AC adaptor is the correct unit for your computer model. The computer may not be able to start from an AC adaptor that is rated for less current (amperage) than the computer requires, even if the rated voltage is correct, and the plug fits correctly in the DC-IN socket. The labels on the bottom of the computer and the AC adaptor show the specifications for voltage ("V") and current ("A") for each device. The voltage level must match exactly. The amperage rating of the AC adaptor must be equal to or greater than that required by the computer
