My acer tablet keeps beeping when i plug it in to charge it

Most common cause of this is faulty charger, the metal connector at end of wire won't connect properly to device charging port.
Test it by putting plug back in Tablet charger port and very very gently wiggle it around very slowly, see if the charging light comes on or flickers. They usually make a beeping noise when successfully charging or the screen lights up. If you get intermittent charging then it's the charger and time to get a new one. Very common, most are USB connectors or small pin types.
If it's still under warranty then send it back to the place you bought it before you try testing it.

yes - it is a usb charging wire that you plug into a power point and the tablet and it powers the tablet while charging the battery

Bad battery

first of all these tablets take a long time to charge. second check the cable were you plug into tablet to make sure the holding clips are working and take hold. My first choice and most inexpensive is to buy a new charger. Also check plug in port for damage. look at warranty to see if it is still covered and get replaced. />

The charger might be defective and not capable to deliver the required current to charge the battery, try a replacement charger.

I just answerd your question

Its a bad battery or connector.

Bonjour,
Il est probable que le souci vient de la batterie alors la meilleure chose ? faire dans ce genre de cas reste de demander l'avis d'un r?parateur.

If it's new bring it back on the warantee, if it is out of warantee, check to see if the power supply is putting out the proper voltage at the plug in tip to the Acer. Make sure the tip is put ALL THE WAY into the hole on the acer.

As far as I know the 101 does not support USB charging just the DC in jack works for charging it. Most smaller tablets do not support USB charging. I have a Acer Iconia as my personal and i doesn't do that. I can't say it is missed. I only have a 5-6 hour battery but can plug in any time to charge without having to have a pc or laptop running.
