Battery/Power Issues with Asus ROG Strix G533ZS-LN025W

[thecm21]

Hello,

I’ve been having issues with my laptop basically since I got it. At the very beginning, the display panel suddenly stopped working one day. The laptop was always sitting on my desk and never dropped or damaged in any way. Luckily, that problem was fixed under warranty.

Unfortunately, right after the warranty expired, a new issue appeared. The laptop only works when connected to the main power adapter. As soon as I unplug it, it immediately shuts down — just like a desktop PC that’s been disconnected from power.

The battery always shows 100% charged, but the system does not seem to draw any power from it. When I try using the secondary original USB-C adapter (the weaker one included in the box, intended for lighter tasks), the laptop also does not power on.

I once took it to an external repair service, and the technician suggested that this might not actually be a battery issue, but potentially a motherboard problem, since the laptop won’t start even with the secondary USB-C adapter.

My model: Asus ROG Strix G533ZS-LN025W

- 15 i9-12900H

- 32GB

- RTX3080

Has anyone experienced something similar, and is there any solution for this problem?

Thanks in advance for any help!

Update on the issue:

After some additional troubleshooting, I noticed that the BIOS does not show any battery information at all. Normally, there should be a “Battery Information” section, but in my case it simply isn’t there. This strongly suggests that the system is not detecting the battery at all.

Also, if it were just a dead battery, the laptop should still be able to power on using the secondary USB-C adapter (with limited performance). However, in my case it does not power on with the USB-C adapter either — only with the main charger.

This points to a problem not just with the battery, but most likely with the power delivery/charging circuit on the motherboard. That would explain:

• why the battery is always shown as 100% in Windows,

• why the laptop shuts down instantly without the main charger,

• and why the USB-C adapter does not work.

At this stage, it looks more like a motherboard (power management IC) failure rather than simply a battery issue.

If anyone has had a similar case and can confirm this diagnosis, I’d really appreciate your input.
