Hello

My wife's LG tablet has been abandoned since Christmas and is completely discharged.  However, it flatly refuses to recharge.  Any advice in this area ?  Regards.

Yah: Leave it on the charger overnight without touching it and try it in the AM.

:)

Tried that, bludgard.  I've tried different chargers, different USB cables.  I've tried trickle-charging it through my PC.   I get the lightning/battery charge symbol showing zero for half a second when I plug it in and then the black screen of total ignorance in perpetuity.

If leaving it connected (for a couple days if necessary) does not help: I would suspect a faulty battery.

The tab::

Recognizes power connected >

Recognizes a battery >

Battery:

Not recognizing power >

Not taking charge.

Sure I am missing a couple hundred troubleshooting tips with algorythms but time and experience just wont allow it.

 

I would rip it apart and fiddle 'round with battery power leads to mainboard (disconnect then reconnect).

This is actually quite a common problem with tablets which become fully discharged.  I know this because of the quantity of queries appearing on the 'net.   There are many simple  suggestions for a fix-  some of which work for some people -  but I was hoping that somebody here with experience of the problem could advise me.   I'm as sure as I can be that it's NOT a faulty battery as some of the solution seekers have reported replacing theirs with negative results.  Thanks for your time though.

No worries.

We repair/service desktops, laptops, tablets, phones, game systems, TVs and practically any other electronic devices daily. We have indeed run into this issue many times with tabs and phones.

I suppose one will have to search out what will work for you and run with it.

Thanks,

Over

 

Edit: One will undoubtedly have to get to the insides to correct the issue eventually (be it you or a service tech). Prayer and hope have little to do with making a battery functional.

 

Edit2: There is also the possibiliity of fauly voltage regulating component(s) (although unlikely-it happens); which requires replacing the on-board-chip(s) or purchase of mainboard that houses it/them.

 

I would def pull/reconnect the battery before anything. Might get lucky....
