Although your adapter is "plugged in" t may have a loose or worn wire/connection internal. Another possibility is the female connection on your laptop may have a loose or worn wire/connection. Your laptop must be getting charged at least some of the time plugged in, hence the 95% level. My suggestion is to check your power adapter with a multi-meter. Be sure to look at the label on the adapter to get the "output" that you will be checking for. If the adapter checks out. it probably is the "plug in" to your laptop. Good Luck!

Sometimes this indicates a problem with the battery. Try unplugging the power cord and see how long the battery lasts. If its not very long, then thats the problem. Its noemally something to do with the charging circuit.
Hope this helps.... Dale

No power. no lights. I have checked the power cord and its like there is no power


Firstly check that there is power to the Ac adaptor, this can be done by seeing if the green power indicator light is on on the adaptor body.

If not, then you have a defective plug, blown 3 amp fuse or the adaptor is fried (not uncommon)
If you have a multimeter, you can set it to 20 volts DC and with the adaptor pligged into the mains, test the DC JACK end! by putting the red probe to the inner part of the jack and the black to the outer part, if no reading, then assume the adaptor is dead.

Best way to check is by testing with an adaptor (universal charger type) to see if that works.

Assuming the adaptor is putting out power, check the output with a multimeter as above and see if the voltage is at the correct level (think its 19 volts on that model). If it is, then move on to the DC jack connection on the netbook

Watch the power indicator on the adaptor, if it is not steady green (ie flashes on and off), ther power is not making a circuit in the alptop and is being "spat back", this can be anything from a blown circuit board in the power circuit, to something as simple as a motherboard main fuse.

If there is a staedy green light but no power at the netbook and the jack connection at the netbook is firm and not sloppy or loose, then you will need to have the netbook dismantled and the fuse checked ( this will also need to happen if the jack connection is loose.

Sometimes, removing the battery, pressing the power button on (with the adapator unplugged) for 30 seconds and repowering with the ac adaptor can reboot the system, but I'd be inclined to suspect the adaptor first

Laptop screen flickers and goes off .


You could have a faulty inverter but
You most likely have a defective CCFL backlight, it may have the following symptom:

  • Screen flashs on red/pink and off.
  • Picture stays on in red and slowly be come normal.
  • Picture flickering with dim display.
  • Picture flickering on and off.
All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp

Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Seems to be no power to speakers.


Disconnect green speaker jack from computer and see if you get a green power light on speakers. If the speakers indicate they have power, your sound card or circuit is shorting out the speakers. If you still have no power to the speakers when disconnected from computer, then no green light means no power to speakers. Either you’re A.C. adaptor is bad or the speakers are shorted out. You have 2 options:
1) Replace A.C. adaptor.
2) Replace speakers.
If you buy new speakers, make sure that they have their own power source (A.C. adaptor).

Laptop will not turn on.


plug it into the wall , most newer laptops will have a power boost while plugged into AC.
check your power cable receptical on the back of the laptop, these are notorious for getting loose.
check the cable on the ac adaptor, these are bad for getting breaks that you cant see in them (run your hand down the cable physically and fell for any breaks while unplugged, then do it again plugged in and watch for lights to flicker on the computer.
look for the power light on the laptop to come on when you plug the adaptor in. if you get a light on the adaptor and on the computer, then the adaptor isnt the issue.
the next step is checking the power button and power supply.. post what your results are here and we'll move to the next step if not resolved.
Regards!

X box 360


Hey tjames2ya,

If your XBox 360 is not turning on, you may wish to verify that the power adaptor is functioning correctly. The power adaptor should have a light somewhere on its casing that shows up green, red or orange when plugged in. Each of these colors is an indication of a different problem:

* Green indicates that power is being correctly supplied to the XBox 360. If the XBox 360 still does not turn on, you will need to contact Microsoft for repairs and support.

* Orange indicates that at least one connection is loose. Making sure that all of the cables attached to the XBox 360 are secure should resolve this type of problem, and allow your console to power on.

* Red indicates that the power adaptor has either overheated or needs to be replaced. If the light is out, this may also be an indicator that the power adaptor is defective, but it may just as easily be a sign that the outlet the XBox 360 was plugged into did not provide enough electricity to power the console.

Unfortunately, in order to reset the XBox 360 you will need power to be supplied to the console. If replacing the power adaptor or double-checking your connections does return power to the console, you may then reset it by performing a "power cycle" (turning the unit off, then back on roughly 10-15 seconds later).

Hope this helps you out.

Sincerely,
Aaron

On button


Look at the power indicator. If it is not lit, no power is being supplied to the computer. Check the following:
  1. If you are using on the battery, it may be low and unable to power the computer. Connect the AC adaptor to recharge the battery pack.
  2. Make sure that the AC adaptor is properly plugged into the computer and to the power outlet.
If it is lit, check the following:
  1. Is a non-bootable (non-system) disk in the external USB floppy drive?
  2. Remove or replace it with a system disk and press <Ctrl> + <Alt> +<Del> to restart the system.
The computer's power management system automatically blanks the screen to save power. Press any key to turn the display back on. If pressing a key does not turn the display back on, three things might be the cause:
  1. The brightness level might be too low. Press <Fn> + <→> (increase) to adjust the brightness level.
  2. The display device might be set to an external monitor. Press the display toggle hot key <Fn> + <F5> to toggle the display back to the computer.
  3. If the Sleep indicator is lit, the computer is in Sleep mode. Press and release the power button to resume.
