If you do not hear any sounds such as a fan, coming from the laptop, and there are no lights coming up on it, it is very likely that your motherboard has failed.

I bought new universal adapter for asus laptop and it charges batery just when laptop is turned off


Problem description: The battery charges only when the laptop turned off. The battery charge LED lights up as normal and the battery gets charged to 100% while the laptop is off.
When the laptop is turned on, the battery charge LED goes off even if the adapter is still plugged in.
Possible cause: 1. AC power adapter failure.
2. Battery failure.
3. Broken/loose power jack.
4. Motherboard failure.
Possible troubleshooting steps and repair solution: 1. This problem could be related to a faulty AC power adapter. It's possible that the AC adapter doesn't provide enough power when plugged into the laptop. To find out if this is your problem, you'll have to test the laptop with another working adapter.Replace the adapter if needed.
2. There is a slight chance that you have bad battery. Test the laptop with a know good battery and replace the faulty one if needed.
3. The battery charge problem could be related to the power jack. Maybe the jack is broken or not making good contact with the motherboard. It is necessary to remove the motherboard and take a closer look at the power jack. Resolder or replace the jack if needed.
4. If the power jack is in a good working shape and new power adapter with battery do not fix the problem, most likely you have a faulty motherboard. Replace the motherboard if needed.

ASUS laptop AC Adapter

HP dv7 simply stopped turning on. worked great


What you would want to try is to remove the battery and see if pluging in the power cord will power the laptop alone. All laptops have this capability and this shouldnt be an issue.

But by testing this and seeing if it DOESN'T work then that means there could be one of two things. Your AC power adapter is defective and should be replaced with one that is compatible with your system or that your connection jack is either loose on the inside or broken completely.

However I would stick with trying the cord first before trying to resoder the joint inside the system. I'd leave that to a pro, going back to the battery if you leave it out for a day that should give it plenty of time to discharge any energy it may have in it and you can plug it back into the laptop to try and charge it again either with the same AC power adapter or a new one. If the battery wont hold a charge and you know it isn't because the jack is loose or the AC power adapter isnt defective then you now know you need to replace the battery. You can google compatible batteries and power adapters online or search specific places like Newegg.com or Amazon.

Hope this gives you a better understanding of what may need to be done to fix this!!

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.

HP DV600 laptop doesn't turn on even on mains.


It sounds like your ac adapter has died, and thus is not charging the battery back up. Test the adapter for power output. If it isn't working, the only option is to purchase another.

Battery doesn't stay charged


The problem is with the battery. All Lithium batteries last for around 1000 charges or so. Since the laptop is 2-years old the battery needs to be replaced.
I Hope this solves your problem. Kindly Accept my solution.

Toshiba satelite A100 rejects AC... often.


Just to humor me, are you using any peripherals with your laptop when this happens, such as a wireless mouse, USB connections such as digital cameras? Try to take these away when recharging.

There seems to be 2 issues here.
1) Recharing batteries: To prepare the batteries for long-term use (I do not know how long you've had the batteries...try draining the batteries (both of them), and then recharging it to full 2x before using them without the AC Adapter. This should clear the problem.

2) AC Adapter only works every other day: When you swapped the power pack, was it with a new AC adapter, or another used one? Also, have you tried using a different outlet than the one you normally use? Let me know how this turns out.

Brand new dvd player just shut off and won't turn on or charge


Your problem is most likly the ac/dc adapter, try your power cord for your car see if that works. if it does then its the adapter. Venturer has had some problems with their chargers.
