Charge Indicator light on HV20 never lights

you can try the power system check by doing the following:

To verify the symptom of the problem, power on the computer using each of the following power sources:
1. Remove the battery pack.
2. Connect the power adapter and check that power is supplied.
3. Disconnect the power adapter and install the charged battery pack; then check that power is supplied by
the battery pack.

If you suspect a power problem, see the appropriate power supply check in the following list:
"Check the Power Adapter"
"Check the Battery Pack"

Check the Power Adapter
Unplug the power adapter cable from the computer and measure the output voltage at the plug of the power
adapter cable. See the following figure
1. If the voltage is not correct, replace the power adapter.
2. If the voltage is within the range, do the following:
* Replace the System board.
* If the voltage is not correct, go to the next step.
NOTE: An audible noise from the power adapter does not always indicate a defect.
3. If the power-on indicator does not light up, check the power cord of the power adapter for correct
continuity and installation.
4. If the operational charge does not work, see "Check the Battery Pack"

Pin 1: +19 to +20.5V (Centre pin)
Pin 2: 0V, Ground (Shielding / Surround)


Check the Battery Pack
To check the battery pack, do the following:
From Software:
1. Check out the Power Management in control Panel
2. In Power Meter, confirm that if the parameters shown in the screen for Current Power Source and Total Battery Power Remaining are correct.
3. Repeat the steps 1 and 2, for both battery and adapter.
4. This helps you identify first the problem is on recharging or discharging.

From Hardware:
1. Power off the computer.
2. Remove the battery pack and measure the voltage between battery terminals 1(+) and 6(ground).
(Terminal 1 is closest to the edge, Terminal 6 is closest to centre)
3. If the voltage is still less than 7.5 Vdc after recharging, replace the battery.

To check the battery charge operation, use a discharged battery pack or a battery pack that has less than 50% of the total power remaining when installed in the computer. If the battery status indicator does not light up, remove the battery pack and let it return to room temperature.

Re-install the battery pack.
If the charge indicator still does not light up, replace the battery pack. If the charge indicator still does not light up, replace the DC/DC charger board.

Few options: either the connection is "hazy" (try moving the plug in the hole), battery is fake or battery has been abused and is empty...

If the laptop battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all. OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time. If the battery drops to an unacceptable charge level then the battery needs to be replaced. Rechargeable batteries will fail if stored in a discharged state for long periods.

Hi there. Your problem seems to be the battery. Usually when the battery is at the end of its life the indicator stays at 0%. If you are still unsure you can go to download.com and get free battery testing software. Good luck...

Try to perfrom power drain. You must first turn off the computer. Take out the battery and unplug the power adapter. Press and hold the power button for 30 secs. Put the batter back in, plug in the power adapter and power ip the computer then observe.

Let me know if same issue will happen.

its a battery problem try exchange it

You either have a faulty ac adapter; a bad power supply in your laptop; a bad battery; or a blown LED indicator light.
1. If the connection is not loose when you plug in your ac adapter try letting the laptop charge for a while. (If you are using the correct ac adapter)
2. Try removing your battery and using the ac adapter. If this works the battery is bad.
3. Try a new ac adapter.
4. Power supply is bad

A few things to try:
First remove the battery from the laptop plug in the power adapter and see if it powers up without the battery in. If this works there is a problem with the battery or the battery driver. If it works login go to device manager and disable the Microsoft ACPI-Compliant Control Method Battery. If battery works then it was the driver if still fails its a dead battery.
Try with just the battery it is probably dead though as its had no power to charge it.
Check if the power adapter has a light on it some have lights that indicate its receiving power. Also check if the lights on the laptop to say the battery is charging even though you indicated it isnt.
Let me know how you go or if you need further help.

This sounds similar to a problem I had. I brought the camera in under warranty and the repair shop fixed it. They shop text is cryptic.
Problem: Camera light keeps flashing, not charge
Solution: Troubleshoot to intermittent switch block control, replace with new one, test OK.

Hi, Try running you laptop with the battery and the AC adapter. If by plugging in your adapter there is no light indicator likewise or no powering up, then presumably there is a problem with the power supply circuitry in the motherboard. Normally the laptop should work with just the adapter, just the battery or both the battery and the adapter. If it will not perhaps your best bet is to seek professional repair service since this would require opening the motherboard. In most instances, this involves an smc fusible link, regulator transistors or even just cold solder or loose connections. Hope this be of some help/idea. post back how things turned up or should you need further information. Good luck and kind regards.
