Question about HP Compaq Presario V2000 Notebook

Battery doesn't charge

The computer is running on ac power. The ac cord is displayed on the taskbar. The front panel "lightning bolt" is not on. The battery monitor does not report charging. I tried two separate batteries. Same condition. What do you think is wrong?

    Thank's for the insight. That was indeed the problem. The aftermarket charger was working only well enough to operate the laptop. The initial problem was no power at all. I opened up the computer and found broken solder joints on the socket. I resoldered the joints. Then I used the universal charger to check it out. I first thought I had not fixed the problem, but I finally measured the output voltage and found only ~15V, too low to charge. Expensive charger though.

    Thanks again.

Is that the original power cord for that? Or was that one bought aftermarket, some aftermarket chargers will only power your laptop and not charge.

Presario R4000 battery is charging but the lightning bolt is not lit


When you first turn on the laptop, does the lightning bolt LED light up for a split second, even before Windows opens? That is a test that the LED is not burned out. If it does, then are you using the correct AC adapter that came with the laptop? Some look identical, but are not as powerful enough to run the computer correctly and you wouldn't necessarily notice a difference except something like the LED. How old it the battery and how long does it take to fully charge?
1. Reset the laptop by shutting down the laptop and unplugging from AC power;
2. Remove the battery;
3. With the computer unplugged and no battery, hold down the power button for 30 seconds. Remember no power on the computer at all for this step.
4. Replace the battery and plug it back in and turn on.

If that doesn't help, search the internet or HP's web site and update the BIOS for your specific system. Look for good directions for doing this and don't run the BIOS update from the internet, you should download the BIOS to your computer and then run it from there. The BIOS cannot be interrupted. If the BIOS is interrupted while installing, it WILL render your computer useless and you will have to replace the motherboard (extremely expensive).

Gateway NV5378u lap top, brand new battery installed and status says 100% charged. When I unplug the computer it shuts off as if there is no battery. Could the new battery be defective?


There are a few things to check. The LED lights can tell you a lot. This will tell you more about the battery:
  1. On the taskbar, double-click the power cord icon or battery icon to open the Power Meter dialog box. Note: If the power cord icon or battery icon does not appear on the taskbar, click the show hidden icons button.
  2. Press Fn+STATUS to view the power status box, which opens in the upper-left corner of the screen. The power status box shows the current power source, the battery charge level, and the power management mode.
  3. Look at the battery charge indicator (if applicable).
    • LED green - Battery is fully charged.
    • LED orange - Battery is charging.
    • LED blinking red - Battery charge is very low.
    • LED solid red - Battery is malfunctioning. Note: This LED only lights up when the notebook is connected to AC power.
  4. Press the battery meter button on the battery. The battery meter lights indicate the percentage of battery charge remaining.
  5. Wait for a Low Battery warning message to appear.
If your battery charge indicator displays what looks like an inaccurate charge, you may need to recalibrate the battery.

To recalibrate the battery as mentioned, try this:
  1. Connect the AC adapter and then turn on the notebook.
  2. As soon as it starts and you see a startup screen, press the F2 key.
  3. In the BIOS Setup utility, use the TAB key to select the Advanced menu.
  4. On the Advanced menu, select Battery Auto Learning, and then press the SPACEBAR to select Enabled.
  5. Use the RIGHT ARROW key to select the Exit menu. On the Exit menu select Exit Saving Changes, and then press ENTER.
  6. At the Setup Confirmation prompt, select Yes, and then press ENTER.
  7. The battery recalibration process begins and a screen opens showing you the progress.
  8. When the recalibration has finished, and the message "Press [Esc] key to exit" appears, press Esc. The battery charge indicator now displays an accurate battery charge.

Hope this helps!!

Zv6000 will not charge will not run off of cord


Try another Cord/Charger with the EXACT same power specs. Has the AC jack been damaged due to pulling on the cord while plugged in?

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 (:

No problem? ?? HP dv8230 status indicator lights flashing.


I believe this would mean that your battery either has a low charge or if you have the AC power cord plugged in, it could mean your battery is bad and won't take a charge

Flashing lightning bolt on Compaq C300


This sounds like a battery problem. The best way to test this is to remove the battery and then power the laptop up with just the power cord plugged in but no battery. If the computer boots then the battery is bad you will need a replacement. Also try letting the battery charge for a day. Be sure that the charging light is coming on when you have it plugged in.

Comp will not turn on also see lightning bolt display


Hi All,


This happens because of static energy storing in the motherboard components.

We can try power drain to resolve this issue.


Try doing power drain by taking out the battery & keep holding down the power button for complete one minute to drain out the power from the computer components. Restart the computer after putting the battery in.
Try restarting the computer only with the AC power, without the battery & vice-versa.

That should resolve the issue, if the issue persists, then you have to contact service center.


Hope that information helped you!!
