Power adpater/battery problem

When ever I run on the battery and then plug the power adapter in the computer will not recognize the adapter. If I turn the computer off and take the battery out and then plug, unplug, and plug the power adapter back in it works. Tried the HD in another computer and did not have a problem with it so it does not appear to be a software issue. The motherboard was replaced in early November. This problem started at the end of November.

You need to check with an HP service site about the mixed battery/power adapter problem. You may have a bad battery.

An adapter should have come with your Kindle Fire HD7 when you purchased it. The USB 2.0 cord is universal, so you could plug it into your computer and charge it that way also (while the computer is on).

I am assuming that you checked to make sure you had all the parts. Included in the Box Fire HD 7 tablet, USB 2.0 cable, 5W power adapter, and Quick Start Guide

My apple ipad is not reponding when iam charging it how do i reset it


Hello,

If you charge your iPad on a power adapter, the iPad should respond while charging, except if your iPad battery is so low the apps need more power to run.

If you charge your iPad on the USB port of your computer, it is normal you cannot use your apps as the iPad is not only in battery charging mode but also in synchronizing mode with iTunes in the computer. You should lose the habit to charge the iPad on the PC and use a dedicated power adapter instead, as dedicated power adapters charge the iPad battery 2 to 4 times faster than the USB port of most computers.
USB port power: 2.5 Watts in general (5 volt x 0.5 A = 2.5 Watts)
iPhone charger: 5 watts
iPad charger: 10 or 12 watts

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.

My toshiba r10 laptop wont turn on the green power light to the front is on but the yellow battery light only comes onn when i plug in the power cord to it and it only stays about 2 seconds


Ok here's what you will do

1) Unplug the notebook from the ac adapter (charger power cord)

2) Take off the battery pack on the notebook

3) Once the ac adapter and battery is off the notebook, hold down the power button for 15 seconds

4) After 15 seconds, let go of the power button

5) Now plug in the AC ADAPTER (OR CHARGER POWER CORD) ONLY (DO NOT PUT BACK THE BATTERY PACK)

6) Now press the power button once.

7) If the unit boots, the unit suffered a slight surge

8) If the unit does not boot and remains dead, the unit suffered a severe surge and may be burned out and needs replacing

I hope this helps and let me know how it goes afterwards

HP 2710P will not power on!


Try power draining your computer first. remove battery and ac adapter, then press and hold power button for 15-20 sec. Expect no response since there is no power source. After that, try if pc will now turn on. If it still wont, possibly it will be needing a motherboard replacement.

Acer Travelmate C112TCi- Won't power on


Hi,
Remove the adapter and the battery from the laptop.
Press the power button and hold it down for 20 seconds(without the battery or adapter plugged in to it). This process is called POWER DRAIN.
Now connect only the adapter and try to turn it on.
If it starts up, there is no problem with the adapter or the laptop.
If it doesn't, it can be either the adapter or the laptop.
You will have to check it with a different adapter to confirm which one is faulty.

The second case is that the computer powers on only with the adapter.
Then you can put the battery back in and try powering it up.
If it doesn't work, try connecting the adapter too.
If still it doesn't work, its a faulty battery.

Sometimes after doing a power drain, the computer will work fine.
If you have any more issues, feel free to contact me.

No power


It will only heat up if power is being used, but it could also mean that the adapter is bad.

check with a multi tester inside for red and outside for black, check to see if you are getting at least 15 volts or higher voltage.

make sure you set the multitester to VDC, Thats Direct Current Voltage or DC voltage.

if you are getting power thru the adpater head try wiggling the tip a bit to see if theres a broken wire inside the head Adapter head tends to break at the tip sometimes.

if your getting power then you might have a broken adapter plug in the laptop, you might a suitable adapter plug at a electronic store or ebay, might need or reqiure some soldering on the board if you dont know how to solder i suggest you leave it to the PRO's.

if no power coming from the adapter then time to replace the adapter, i figure adapter last about 1-2 years before they need replacing due to wear and tear and neglect. If you do not take care of your electronics they will not take care of you!.



Good luck
