Battery Charging Problems

About six months ago, I started noticing some problems with the battery on the Asus ROG G751JY. At first, it manifested in the battery discharging even while being plugged in. I thought that was quite odd because it only happened while playing Civ VI. After doing some research online, I learned that was a common occurrence with laptops and high-end graphics gaming. Simply put, the power going through the power cord and brick cannot produce enough power fast enough to run games like Civ VI, so the laptop had to use both the connected power cord and the battery to power the game. I never noticed that with Civ V or even the earliest versions of Civ VI, but with the Rise and Fall update, the power demand appeared to increase. After learning this was common for gamers, for a while I did not do any more trouble shooting, but learned to monitor the battery level so as not to be shut down suddenly in mid-game.

Then sometime a few months ago, the battery would not recharge upon closing the game and going back to regular power usage. When all else fails, reboot or shut down and restart is one of my mottos. So that became my go to solution, because after shutting down the computer and waiting a few minutes, it would begin to recharge. Sometimes I had to unplug the power cord from the computer, wait a few minutes, then plug it in again for the recharging to start. That led me to more trouble shooting research online and I found one particular site very useful. It identified eight possible causes for this problem. Some really obvious “operator error” possibilities like checking to see that the power cord is really plugged in to both computer and functioning A/C outlet and checking to see that all connections, such as power cord to power brick, were secure. Others were more ominous.

When the problem became noticeably worse, such as the issue occurring with Minecraft as well as Civ VI, I decided I was going to need to check out the more serious potential problems. From previous laptop experience, I knew sometimes taking out the battery to shut down any battery power connection and booting computer without battery would help determine if the battery was bad and needed to be replaced. So, I set out to do that. The only problem was with the Asus ROG, the battery was not easily accessible and the back of the computer had to be dismantled to get to it. That turned out to be too daunting a task for me, so I opted for taking it in to the shop.

I asked them to check the three options I suspected: 1) bad battery, 2) bad power connector on the computer (where cord connects to computer), 3) failing or bad power cord/power brick. They did not find any of the three to be the problem, so I took it home again, still hoping for it not to be the worst – a motherboard problem, although the most likely possibility was in fact the battery sensors on the motherboard.

I muddled along for maybe a couple of more weeks before eventually the battery would not recharge at all no matter what I did. Back to the shop. They rechecked everything and eventually settled on probability that the power connector was the likely culprit, so ordered a replacement. The first one they got was the wrong one, so another had to be ordered. After installation, the problem still persisted and so the test of a boot up without the battery in the computer was the final straw. Even then it would not boot up at all, confirming it was a problem with the motherboard. Needless to say, replacing a motherboard was too costly to consider.

So, RIP Asus ROG G751JY.
