Question

Laptop Battery (Plugged In, Charging) but stuck at 70%

Mar 11, 2017 10:09AM PST

Hello,

I know this is a fairly common problem as I've found various links and articles online that address this issue; however, most of them just say that the laptop is set to "Desktop Mode" and purposefully will not allow a charge to exceed a static number to preserve the battery. This does not seem to be the case for my laptop.

First, I have an ASUS ROG G751JT-DH72 that has been working beautifully for a year or so. This past december, I noticed that I was having a very similar issue as the one described in the Subject Title, but it would read as (Plugged In, Not Charging). It was then that it was determined that the battery was faulty, which I know can happen after a year or two, so I had it replaced (only a few weeks ago). Since then, the machine has worked beautifully once again until late last night.

If you couldn't tell by the family this laptop belongs in, it's a gaming machine (and I fairly decent one at that for a laptop), and so it is used frequently for that purpose. While running the game Ark: Survival Evolved last night, the machine suddenly turned off. Just... dead; no error codes, no warnings, no nothing. I understand that this can commonly be caused by an overheating issue, and I had been playing the game for hours yesterday. This morning, however, it does the same thing. This time, though, the machine powers off after a moment or two once Ark is launched. I ruled out the issue being a game-specific problem by launching other games: same problem.

So, in short:

-- New Battery
-- (Plugged In, Charging) but stuck at 70%
-- Machine powers off abruptly when anything "power-intensive" occurs
-- If I unplug the power cable, the machine immediately shuts off
-- Everything has been working fine on this new battery until now, no other changes made
-- Already uninstalled/reinstalled/updated Microsoft ACPI-Compliant Control Method Battery driver

Any ideas as to what the issue could be?

The clue is the power down when unplugged.

That can mean the battery or it's circuits is gone. I'd try another battery just in case because what's next is expensive. (motherboard.)

I've Checked the Connections...

I imagine that if I need to replace the entire motherboard, I might as well scrap this machine and buy a new one... Just to be sure, I opened the machine up once more to verify that all the connections were still in place. Is there any kind of test I can run on the battery to see if it is faulty? I ran both the battery report and energy report from the command prompt, and from what I can tell, both indicate that the battery was functioning normally and was only slightly under it's original capacity...

The tests are

1. Unplug the charger and the laptop can power up.
2. This battery in another laptop of same make/model (we have that luxury in the office.)
3. Try another battery and charger.
