My Acer Aspire 5720 laptop won't charge while it's running

My Acer Aspire 5720 laptop won't charge while it's being used. It operates perfectly if it's kept on mains power when fully charged, and works fine off the battery, but when I let the battery run down and then try to connect it to the mains to charge it up while still working, it charges for a minute or so, then just kicks off the charger and the battery and power lights flash red. The battery and the AC adapter have been replaced, and I have updated the battery drivers but all to no avail. Is it a problem with the physical connection?

Hello there:
try removing the battery from the computer and turning on the computer to see if the power cord works correctly if it does inspect the battery and clean the terminals on the battery and computer and put the battery back in while it is still on now you should see the battery show up on the taskbar if not right click anywhere on the desktop and go to properties and than go to than go to screensaver than look towards the bottom and you will see power click on it and you should see the options for the battery ok sorry this was so long but i needed to explain it in full

Sounds like the ac adapter is too weak or the power jack is loose or bad.

My acer aspire 5720 cursor is stucked in the middle ,please help me to unlock and there is no unlock button near pad


JUst use the driver cd that came with the laptop ...and insert it and reinstall the driver for the touch pad..This will make it functional again ..Or , if you do not have a drivers cd go to acer.com and under support feature look for your model and operation system ..and download the driver for the touch pad..and run it to insdtallagain ..This should fix the issue if the pad is not physically corrupted..
Another method is to engage the system restore..and restore the system to an earlier stage when the pad was functional ..For to do that go to start ..all programs ...accessories ..system tools ...system restore..
Choose on the calendar a highlight date ..but be sure the date chosen is one you know for sure the system worked perfectly ..and click restore..
The computer will restart and restore to the date you selected... and will work again ..
good luck and have a nice day !

Hi I have a acer aspire 5720 laptop had it about 1 year the orange light on the front which shows battery charging started to flash and when I moved the charger wire it flashes on and off I bought another...


Usually when you see this flashinf indicator it is a failing battery. IT maybe that some of the cells in the battery are failing and refusing to accept a charge, in that case the battery will actually damage the charger.

Battery not detected


Either both batteries are dead or your battery charging system in the computer is dead. Best thing is to try yet another battery or try your batteries in somebody elses laptop.

Battery does not charge


You can try to recalibrate the battery but from the sound of it, you may be better off purchasing a new battery. You can get the brand name for about $110 average or a compatiable battery for about $80.

Good Luck

Acer Aspire 5720-6438 recovery cd/driver cd


if you need drivers, you can download it from www.acerpanam.com.
for recovery cd, i don't think acer have it online, you need to order it from them.

FYI, if you haven't delete the partition in your hdd, you can use alt+f10 to re-install your Operating system and after that, you can create your own recovery cd.
