Question about HP Computers & Internet

Power issue. Battery is completely dead. If i plugged power adapter and unplugged battery, it won't work. Having both plugged and battery in, will work after a while. Then in about 25-30 minute, screen will start to go dimmer and back normal over and over. Will eventually say that we need to change battery or power outlet then will shut off just like that.

Nc6000 multibay battery does not recharge


Perhaps remove the multi-bay battery, and let main battery charge all the way. Then reattach multi-bay battery, and see if it's recognized.
(Will charge)

That is AC adapter (Charger) removed, then remove multi-bay battery.
Plug AC adapter back into laptop, THEN plug AC adapter into power.

[You do Not want to unplug an AC adapter from a laptop, with the AC adapter plugged into power. Could be a power surge/voltage spike. Unplug AC adapter from power, when plugging into laptop, or unplugging from laptop ]

Main battery charged, unplug power to AC adapter, unplug AC adapter from laptop. Plug multi-bay battery in, then AC adapter.
(Then plug AC adapter into power)

C640 compltely dead


POWER SUPPLY & BATTERY PROBLEM
If thelaptop 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 andwill lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up at all. OR Thebattery shows a 100% charge but when the adapter is disconnected the batterydrops off to zero capacity in a very short time. If the battery drops to anunacceptable charge level then the battery needs to be replaced.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.

Dell Inspiron 1521 battery not charging


Laptop batteries power a laptop when it is not connected to an electrical outlet. If the laptop battery fails to charge when the laptop is plugged into an electrical outlet, the battery is likely dead and needs to be replaced. Unfortunately there is no way to fix a dead battery. However, while a dead battery is the likely cause, it is not the only cause. The AC adapter may be broken, in which case the battery won't charge, or the battery contacts may be dirty and need cleaning. Prior to replacing the battery, perform simple tasks to ensure a dead battery is the cause of the problems.

1.Power down the laptop. Gently pull the AC adapter from the side of the laptop for removal.

2.Place the laptop in front of you, bottom side up. Locate the battery release mechanism. This can be a button that slides or needs to be pushed to unlock or release the laptop battery from the housing unit. Press or slide the mechanism. Slide or lift the battery from the battery bay for removal.

3.Insert the AC adapter into the side of the laptop. Power on the laptop. If the laptop does not power on, ensure the AC adapter is securely plugged into a working electrical outlet. If the electrical outlet is working and the laptop won't power on, the AC adapter is not properly working and needs to be replaced. Remove the AC adapter.

4.Dip a cotton swab in a small amount of rubbing alcohol. The cotton swab should be damp, not dripping wet. Lightly rub the dampened cotton swab onto the battery contacts and battery bay contacts to remove dust, buildup and grime. Allow the contacts to air dry.

5.Align the battery over the battery bay. Either press or slide into place. A clicking or snapping noise produced from the locking mechanism will confirm the laptop battery is securely locked into place.

6.Install the AC adapter. Allow the AC adapter to fully charge the battery for 8 hours.

7.Remove the AC adapter. Power on the laptop. If the laptop does not power on, the battery needs to be replaced.

HP dv7-1448 not powering up, even when plugged in


Try this:

1. Unplug the machine and remove the battery.
2. Hold down the power button for 30 seconds with the battery out and unplugged.
3. Replace the battery and plug it back in.
4. Try and power it up.
5. If it doesn't work, there is the potential that the battery is dead and the AC adapter may be broken. This would prevent the battery from being charged and it wouldn't work when it was plugged into the wall, so try and borrow an adapter from the same laptop to test this.
6. Hopefully something worked, because if it didn't, the laptop may bed dead. Hope this helps!

Dell Latitude D600 won't power on w/ or w/out power adapter


the problem is really mysterious. because in most of cases the battery is the villain. and when it is replaced the issue should be over. there are no other components of a laptop which is directly or indirectly related with battery perfomance.
any way get back me with more details like the age of system and number of times taken to service center etc etc @ deepuunni1985@gmail.com

Travelmate only powers up with battery inserted. But AC still charges battery. Orange light goes on and of


Sorry to tell you this but you may have a problem with the charging system. That will require you to return it to Acer or an Acer service center. You can also try this. I got this from Acers' travelmate support website:

If the notebook does not power on:

Make sure the ac adapter is correctly plugged into the notebook and into the power cord.

If everything is plugged in correctly and it still will not power on, follow these steps to complete a ‘power reset' of the notebook.
  1. Unplug the ac adapter. Keep ac adapter unplugged.
  2. Remove the battery and keep the battery unplugged.
  3. Hold the power button down for 15-20 seconds. (Nothing will appear on the display and none of the lights will light up.)
  4. Release the power button and plug in the ac adapter ONLY. (Please note that a power indicator light should be lit on the ac adapter when it is plugged in).
  5. Normally power on the notebook.
  6. If the unit does not power on, remove the ac adapter and insert the battery into the system.
  7. Plug the ac adapter back into the system, the battery charging indicator light will light up.
    If the battery charging indicator light does not light up, the ac adapter may not be providing proper power to the unit, and may need to be replaced.
You can aslo google your specific model of Travelmate to see if others are having this issue.

No power


As far as a reset button is concerned you can hold down the power button for a few seconds to turn the power off completely and then power it back up.
If your having power issues and you have a new power adapter thats known working you can try disconnecting the power take out the battery leave for a few seconds then re-insert plug in power and try again.
If this fails try starting just with battery power, if this fails try taking out the battery and attaching just the power adapter and starting up.
Also check that the battery is getting charged there should be a light on the notebook that tells wether its charging.
If this all fails you may have damaged the power adapters connection to the notebook when you bumped it. Hence the battery cannot get recharged to start up.
Let me know how you go.

    If the battery charging indicator light does not light up, the ac adapter may not be providing proper power to the unit, and may need to be replaced.
Also, depending on whether your power went down "clean" (quick and stayed off), or went down and quickly came back on and off many times. Or when it came back on "clean" (came back on quick and stayed on), or it came on then off many times, your power supply may have been damaged from the power surges Are you having any problems with any other appliances?

Travelmate 2300 won't power on


The problem could be your bezel.  Remove the 3 screws from the hinges from the rear and you will be able to remove the black strip above the keyboard (after removing the screws, make sure laptop is layed wide open)  once removed, press the button on the motherboard under where the power button is.  If the unit still does not power up, then your motherboard is bad and needs to be replaced.  If it does power up, you need to replace the bezel.
