My laptop is Acer Aspire 4937G, and it only charges in off mode. I tried to boot it in AC power but it’s not working..

When we bought it, we never really use the battery that much we always use AC power, but after I place the battery while on AC power, this problem started to occur.

Sometimes the battery will charge while ON but many times it will not.

What will I do? (-_-)

I have a gateway mx6920 laptop with model: MA7. It will run off a charged battery but will not charge a battery or run off ac adapter. AC adapter is good at 19vdc. I thought it might be the 4407 mosfet near the plug. I have voltage up to there but have no gate signal. I do not know where the gate comes from. Can I jump out the mosfet here or is it regulating the incoming voltage? What do you suggest? Thanks

Hey all…I have a Samsung q45..and it’s begun the dreaded plugged in not charging thing too.

I know the jack needs a wiggle, which could imply a bad connection to the motherboard, but still, she charges when off, and sometimes when on and sometimes when sleep. So it’s an error I can’t repreat under controlled situatons.

I think it’s may be something to do with the amperage of the supply – I agree it needs to be high to make sure enough energy gets to the battery, but i read Neil’s reply and am interested to see if the new powerjack fixed things…I’m not sure it will cuz this plugged in not charging problem seems to be very widespread.

To me it seems as if we’re using smart Li-ion batteries, perhaps they are not reporting their state correctly to the operating system…? I heard there was a global laptop battery problem recently to do with some issues in the East..?

Hi All !
I think my laptop(ThinkPad R50E) not supplying full voltage charge to battery in on/off condition .
I tested it on battery bay contacts ,and it’s only 9.0+,when itself battery is 16 volt one.

Ok. Flashed the Bios. Had the power jack re-soldered. I also wiped the HD and did a fresh install. And guess what? It worked. For about a week…then it started again. A check of the power cable connection to the jack insert confirmed a jiggle had the power/charging lights blinking on and off. Charging and not charging like a mind of it’s own again. This time I’ll REPLACE the power jack and see what gives.

Thanks for the heads-up Freak on the bios flashing. Made sure it was a full battery. If this doesn’t work I’ll try a new power adapter.

Neil,

I am going to flash the bios

Be careful updating the BIOS while the laptop running on the battery power. If the laptop shuts down during the BIOS update, the BIOS can get corrupted and your laptop will never boot again.

I have a Toshiba A70 with same problem. The charger will only charge the battery when the laptop is off.
As soon as windows starts or I go into the setup menu at boot the charging light goes out. I have just had a mate re soldered the power jack to fix the bad connection but it has not fixed the charging problem. I am going to flash the bios and wipe the hard drive then start from scratch to see what happens. Personaly I think it’s the AC adapter.

I have the same problem with a Toshiba P35 laptop. It is not the power jack. Will charge when the computer is turned off. When windows will start, the battery led will go off and the laptop will run on the battery even the AC is plugged in. The 20v AC will really help? I just bought a new battery, and the same problem. It is not the battery and it is not the power jack. It is or windows or power supply needs more volts.
Who solved this problem? please help
