The laptop fails to power on without a connection, yet functions properly on battery backup.
Hello everyone. My Asus TUF F15 laptop (FX507ZV4) sometimes shows the battery indicator flashing orange during charging. Once the charging cable is removed, the battery level stays stuck at its previous value and stops charging. The device also fails to indicate battery drain when it's in use while charging. I looked into this issue on a forum and found a thread that suggested not to try reviving the laptop. I tried two temporary fixes: 1) Let the battery discharge fully before recharging (not ideal), and 2) When the problem occurs, turn off the laptop, hold the power button for a minute, then press the caps lock light to restart. Using this second method usually gets the laptop running with the current battery level. I'm posting this to help others who face the same problem, as I've never seen the second solution before.
It seems like the problem might be with the charger or the battery itself. I’d point at the battery and replace it if needed—it could resolve the issue. Even if the battery functions perfectly, the internal controller inside might be faulty, affecting how it checks charge levels and usage. Typically, after 2 to 3 years, batteries start to degrade and can fail, which might also affect the power stage board. While rare, the power board could be damaged too, especially if the linked issue applies. It’s more likely a charger or battery issue than a power state board failure.
Everything seems to function correctly except for the fact that your laptop no longer charges properly. It probably means you need a replacement battery. If that doesn’t help, there might be an issue with the motherboard’s power management or battery control circuitry. Alternatively, the charging unit itself could be faulty. Those are the main possibilities I see.
I don't rely on Windows but instead use running upower -i /org/freedesktop/UPower/devices/battery_BAT0. It returns the native path: BAT0 vendor: AS3GWAF3KC model: GA50358 serial: 0427 power supply: yes updated: 29 Eki 2025 14:05:56 (1 sec ago) has history: yes statistics: yes battery present: yes rechargeable: yes state: pending-charge warning-level: none energy: 64,284 Wh energy-empty: 0 Wh energy-full: 78,395 Wh energy-full-design: 90,005 Wh voltage-min-design: 15.86 V capacity-level: Normal energy-rate: 0 W voltage: 16,278 V charge-cycles: N/A percentage: 82% capacity: 87,1007% icon-name: 'battery-full-charging-symbolic'. It seems to be functioning normally most of the time. Occasionally, if it doesn't start, the laptop won't turn on unless it's properly connected. Using any of the suggested fixes has worked for a few months. I think I should return it for warranty service before it stops working completely, which would be frustrating since I depend on my computer for work. I assumed the issue was software-related until now found a temporary solution. Edited October 29, 2025 by quinceenjoyer Keeping two distinct messages in one.
Your battery shows 87%, which suggests it’s nearing the end of its life—likely around 2 to 3 years old. You might want to consider replacing it with a new one from Amazon for testing. It’s possible the battery isn’t performing well, causing occasional issues. The power brick is probably not the issue; most devices either work fine or stop completely.
