I just bought an 210-2081NR HP Netbook and started to present shuting off of the screen every time we try to charge on AC Power. We contacted the HP chat online and they did many changes. Now is worst. The screen works only for a few seconds. The computer continues working but the screen is off

the above is fail sorry I am. no pointed fingers
my wild guess 99% batter is bad as most are.
good luck to you.!!!

A netbook brand new? Let me guess, an Acer One Aspire? There is no detail about the devicein question here.
If it's brand new, just return it, warranty. If it's an Acer One, you probably need a patch for the BIOS which by the way, is kin dof hard to get. Search for BIOS patch for XXXX (netbook model)

You may have a DC connector problem:

Symptoms of a broken power jack
1. If you wiggle the power cord or the AC Adapter connector on the back of the laptop, the power LED and battery charge LED start to flicker.
2. Battery will not charge in the laptop.
3. Laptop runs fine off a charged battery.
4. With the AC Adapter connected the laptop appears to be dead.
No power LED or battery charge LED activity.
5. Laptop randomly powers off without any warning.

If your laptop is out of warranty, then you can fix the problem by re-soldering DC-IN jack on the system board. If it

Hi,

Here are some steps that can help you resolve the issue.

First, try removing the ac adapater and the battery and press and hold the power button for about 10-15 secs to remove the flea power. Then try to deattached the power cable and the power brick and attach it again properly, plug it to the computer without the battery and try to turn on the computer. If still the same problem try a good known power socket, if your using power strip try to plug it directly to the wall socket. If nothing works, try a good known ac adapter, or try you ac adapter to a good known working computer. If a good known ac adapter didnt work, contact HP as this is a power supply issue on the computer (power supply are mostly attached to motherboard for portables) contact HP to check your warranty and have it serviced. If the good known ac adapter works, contact HP to check the warranty and have the AC adapater replace or simply replace the ac adapter.

I hope this will be able to help you.

Thank you for choosing Fixya.

hi,

nope this is not normal. I have a article included below from hp. read this and you will understand the problem and also some ways on how to fix it. The blinking lights is a code on where the system fail or what component that fails.

Hope this helps you.
Don't forget to rate me OK!
Thanks for using Fixya!

HP Black screen error codes

Support details

This document pertains to HP Notebook PCs with the HP Unified Extensible Firmware Interface (UEFI) beginning in late-2008.
On startup, you may see a blank screen. If the diagnostic utilities detect a specific problem with hardware components, the fan turns on, but the screen remains blank. To help identify the cause of the problem, various LED lights on the keyboard blink a series of codes.
The diagnostic utilities use the LEDs near the Num Lock or Caps Lock keys to blink a series of error codes. At the end of the series the blinking stops. The pattern of blinks will occur any time you attempt to start the computer until the error is resolved.

Battery power LED blinks

The Battery power LED indicates the condition of the power supply. When starting the computer, or when the computer is in operation, use the chart to identify the power condition.

Battery low charge or failure
Battery power LED blinking Battery Insufficient charge on the battery

LEDs near Caps Lock and Number Lock keys blink when starting notebook
The LED lights near the Caps Lock and Num Lock keys will blink if an error is detected during the start up process. The LEDs will blink a number of times in a sequence and then stop. The number of blinks in the sequence indicates what component caused an error when it was being tested during start up.

If the LEDs stop blinking and the computer does not start, you can press the power button again to repeat the tests. Count the number of blinks, and use the chart to identify the error condition.
Knowing the number of blinks is helpful when you contact an HP support agent for technical help.
Caps Lock/Num Lock LED Component Tested Error Condition

LEDs blink 1 time CPU CPU not functional
LEDs blink 2 times BIOS BIOS corruption failure
LEDs blink 3 times Memory Module error not functional
LEDs blink 4 times Graphics Graphics controller not functional
LEDs blink 5 times System board General system board failure
LEDs blink 6 times BIOS BIOS authentication failure

Error code explanations
The sections below provide some common explanations for each error code listed in the table above.

AC Adapter not connected or battery low charge
When the computer is on battery power only and the AC adapter is disconnected, if the Battery Power and Caps Lock / Number Lock LEDs do not glow, there is either a very low change or no charge in the battery. Connect the AC power adapter, verify that the battery power LED glows, allow the battery to charge for 15 - 30 minutes and then attempt to start the computer. If it starts, run the battery test and calibrate the battery. If it does not start, if possible, connect a replacement battery to verify that the battery is the problem.

If the computer does not start after charging the battery, remove the battery and connect the AC power supply. Verify that the battery power LED glows, and then attempt to start the computer. If the LED still does not glow, either the AC adapter has failed, or there is a bad connection between the adapter and the system board. If possible, connect a different AC power adapter to verify that the adapter is the problem, or contact HP for support which may require a service event.

Insufficient charge on the battery
If the battery light LED (which looks like a lightning bolt ) flashes, the battery has insufficient charge to start the computer. To resolve this error, try the following solutions.

*
Connect the notebook PC to AC power and attempt to start the computer again.
o
Check the AC adapter to confirm that all of the plugs are securely seated.
o
Determine if the power LED on the AC adapter is lit (if available) to verify that the computer is receiving AC power from the wall outlet.
*
If the computer operates on AC power correctly, charge the battery for thirty minutes to one hour and then restart the computer.
NOTE: Charging the battery for this length of time is called "trickle charging". Trickle charging is a continuous constant-current charge at a low rate, which recharges the battery slowly when it is in a deep discharge state. Deep discharge occurs when a battery is left unused for extended periods of time.

The computer processor (Blink code 1) has stopped functioning properly. Contact HP for assistance.

BIOS corruption failure
If a BIOS corruption error occurs (Blink code 2), you may not even notice the blink codes, because as soon as the computer recognizes the error, it restarts, attempts to recover the BIOS, and then restarts again. You may notice an extra-long startup process as a result, and a message indicating that the BIOS has been recovered may display on startup. If this occurs, update the BIOS on the computer. For more information, refer to the HP Notebook PCs - Locate and Install Updated BIOS, Drivers, and Software .

Module error not functional
If you experience a memory failure (Blink code 3), follow the guide in the table below.
If Using Original Memory If New Memory Is Added
Reseat the memory.

If reseating the memory does not resolve the problem, try replacing the memory with new memory. Reseat the memory.

If you continue to experience this error code after reseating the memory, the problem may be with the memory itself. Take the new memory out of the computer, put the original memory back into the computer, and then retest it.

If you do not feel comfortable reseating the memory yourself, take the computer to a computer retailer and ask them to reseat it for you.
NOTE: Some memory module errors may allow the computer to start but will then cause the computer to restart and display a blinking error code.

Graphics controller not functional
If you experience a graphics controller failure (Blink code 4), contact HP for assistance.

General system board failure
A general system board failure (Blink code 5) is the failure of a component not covered by the other LED error codes. Contact HP for assistance.

BIOS authentication failure
The BIOS authentication error (Blink code 6) is extremely rare. It is the result of a discrepancy between the BIOS and the hardware that is installed on the computer. This error occurs when the BIOS cannot authenticate signatures from the hardware on the system. The purpose of the BIOS authentication is to be sure that no one has tampered with the BIOS on the computer.
If a BIOS authentication failure occurs, the computer automatically performs a BIOS recovery. If the computer does not automatically recover the BIOS, manually perform a BIOS recovery. To manually perform a BIOS recovery, press all four arrow keys at the same time to cause the BIOS to go to the EFI partition to find and recover the current BIOS.

With an extensive use of the notebook,
some times notebook would store some static charges which
indeed will stop the notebook from powering up or charging
the battery. The procedure to remove this static charges from
the notebook is known as power drain. Performing a power
drain procedure will not effect any personal data or delete
any pictures from the hard drive on your notebook.
I recommend you use Power Drain procedure by following these
steps:

1. Disconnect the AC Adapter.
2. Remove the Battery.
3. Hold the Power button down for 30 seconds to 1 minute.
4. Reconnect the AC adapter.
5. Turn on the Notebook power.

Try updating the latest BIOS from the Acer Website.

If your computer won't charge the battery, but the battery charges fine in another computer, and you are sure that the charger is good, then your problem is probably the DC power jack. If you wiggle the end of the power cord where it attaches to you laptop, and it starts charging properly, then the DC power jack is broken.

Try to update bios n check it out..

I just found the most protracted set of instructions to reset it for reference.

1. charge on ac only = 8 hrs
2. remove battey, soft reset, reinsert battery
3. charge on ac only = 30 minutes, remove battery, remove power, hard reset then soft reset.
4. charge on ac only = 4 hrs
5. Power off. Soft reset.
