SOURCE: The battery light blinks after shutting down my hp

The same thing has been happening to my tablet lately, as well. However, on mine, that corner of the computer is slightly damaged (from shoving it into my backpack too roughly, i guess). Is your hp damaged? Otherwise, it's probably a hardware problem.

Why does innotab charging light blink when charging and will not charge?


the charge imdicator is suppose to blink when you plug the toy to the wall adaptor. if it doesnt blink then there's something wrong with either the adaptor, the adaptor port on the toy or the rechargeable power packs. now i said that the light is suppose to blink. but the frequency of the blinks shouldnt be fast. if that's the case clean the compartments and re-insert the batteries. if you are still having problems try the ff T/S:

1)remove the power packs, plug the toy to adaptor and turn it on. if it turns on that means your adaptor is working.
2)remove the adaptor and try using just the power packs.
3)try using 4aa batteries.

if the toy turns on with only one of the power sources stated above you better call vtech hotline.

How do you know the battery is good? does the multimeter really read more than the battery should give, according to what is printed on it?
A 3,7 volt battery, should give at least 3,8, wham not connected. A 7,2 at least 7,4. Because the printed voltage should be on the connector, when you are discharging the battery.

When your charger is blinking, it could indicate the battery is not well. The Ri can be to high or something else, is wrong, and that is ht the charger won't or can't charge.

My HP Elitebook Revolve got dirty from the sleeve I was using. I need to clean it.


Turn it off, remove any battery or plug sources. Hold down the power button for five seconds afterward to power cycle it. Once you are done, take a rag and dampen a corner of it and wring it out. Do not use a wet towel, make sure it is only damp at best, because you do not want to get water into the keyboard or anything important that could cause your netbook to no longer work.

Wipe down any dirty spots slowly, and dry them with a circular motion, so you wont leave as many streaks. It's pretty easy and quick to do, just make sure you don't use that much water, at all. If you want, there are products you can buy such as electronic cleaning wipes and aorosol air cans made to blow dust out of keyboards.

Black screen


The power cells may be defective and thus the battery will no longer accept a charge. Replace the internal power cells.

Hp elitebook 2730p I left the tablet on and when I came back the screen was blank. I can't get the tablet switched off or get the screen to work and I think it might overheat if I leave it like this -...


Hi,

Either your laptop had gone to sleep or hibernate mode. You can set the timers under Power Options on the Control Panel for the laptop to go on sleep mode or hibernate mode if idle for span of time.

You can wake up the laptop by touching the touchpad, pressing a key or pressing the power button.

However, if above options will not work, the only option for you is to press and hold the power button for at least 5 seconds to completely turn off the unit. Try to power on the computer if it will boot up okay.

***ADDITIONAL NOTES FOR CASE TO CASE BASIS**

If you still get black screen, remove the battery and the ac adapter (charger) then press the power button for at least 20 seconds to discharge power in the motherboard. You can now reinsert the battery and power on the system normally.

***NOTE: If the computer will not boot up, the LCD or the motherboard might have failed.

Hope this helps.

Laptop hp compaq tc 4400 is not charging , during adapter connected to laptop and turning power/standby led ... it doesnt switches on, instead battery charging led blinks 4 times, and doesnt turns on, so...


Whenyou connect the power adapter into the laptop, does the power LED lightup? If not then - The battery adapter or the adapter's power lead or the laptop's powersocket could be faulty. Check power adapter's DCplug that connects into the laptop power socket with a multi-meter, the voltageshould be slightly higher than the voltage that is printed on the label on thebottom of the adapter. If the voltage is zero or way below the voltage that isprinted on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK thenconnect it to the laptop and power it up, then look at the power/batterycharging LED light and wriggle the power plug in the laptop's powersocket. If the power/battery LED light flashes and in a certain position thisLED light stays firm, then the power socket is either faulty or it has a drysolder joint where it is connected to the motherboard. This can be repaired but itrequires the laptop to be completely dismantled to get at this power socket andrepair. If you cannot DIY then I suggest you get a quote first.

The battery light blinks after shutting down my hp elitebook 2730p. Both the hard drive and power lights are off. What would cause the battery light to keep blinking after the pc is shut off?
