I have kept restarting but the battery charge light only flashes but the laptop does not start. Checking the battery with a voltmeter shows that it has a charge of 10.8 volts which is the correct rating according to the manufacturer.

Check your Adapter Cables properly connected or take your battery from the Laptop and put it back. Then try restarting. If nothing helps check your Adapter with another same model Laptop. If the Adapter working well then your Battery is dead!.

SOURCE: Battery light on my hp probook 6550b flashes when i try to charge it but it will not turn on!!! How do i fiix it?

flashing battery light is normal when the battery is empty ,and the orange led should become steady when you insert charger then it should turn to blue and after the battery is fully charged the led is turned off, i think the problem is that no charging happens check your adapter and the DC input

SOURCE: hp probook 4530 ac connected indicator flashing. will not power up

Remove the battery, Plug in the AC charger. Push and hold the Power on button for 45secs. If this doens't reset. The fault is most likely the System/Motherboard. If the unit is under warranty, contact HP and arrange a repair.

SOURCE: hp 4510s not charging

Okay, if the unit boots okay, and only getting to 80% charge it could be a Windows 7 issue not reporting the charge correctly. Check the Microsoft Knowledge base for a resolution.

Otherwise it could be a faulty mainboard.

With a laptop that becomes completely un-responsive to all keys even the power key, then you last resort is to un-plug the laptop and gently remove the battery. This will power down the machine. Leave the battery out while you are troubleshooting the problem.

The problem is most likely the video cord running from the LCD screen to the motherboard that has come loose from the plug socket, or there is a intermittent issue in the cord itself.

Turn it off, take out the power supply and battery. Now open it and take out the button battery. With those things out, press and hold the power button for 10 seconds to drain residual charge. try to boot it up. It should work now

I have ProBook 6555b for just a few days and my mute button is stuck in orange. No matter if sound is mute or not, button doesn't change to light blue..


I'm not totally sure with the specific model you mention, but I DO know that many of the HP 6xxx series laptops, the light board above the keyboard are touch sensitive, have you tried actually using your finger to touch the amber light itself and see if it changes to blue? (or the volume bar?)

Try tapping a few times with your finger and see if that helps.

Good Luck
