Why is the pc charging on power off only?
I’ve been facing an issue with my PC where it only seems to charge when it’s turned off. It’s frustrating because I can’t use the computer while it’s charging, and it makes me wonder if there’s something fundamentally wrong with the device. The problem started out of nowhere, and consistently, every time I shut it down completely, it charges as expected. However, the moment I power it on, the charging stops immediately. I’ve checked the charger and power outlet, and they seem to be working fine with other devices. I also experimented with different power settings and even updated the firmware, but nothing seems to change this behavior. I’m starting to worry if this indicates a bigger underlying issue with the hardware or the battery management system. I really need to understand why this is happening and what could be causing such a peculiar problem.

In my own case, I discovered that environmental factors such as overheating could impact battery charging. When the system operates, it generates heat, which might cause thermal throttling in the charging mechanism. Using a cooling pad or ensuring proper ventilation can keep your laptop cooler and might facilitate charging when powered on. Additionally, software conflicts could be at play. Performing a clean boot could reveal if start-up applications are interfering with charging. I also found that a pre-installed power management utility created conflicts with the Windows settings. Lastly, don’t forget to check for any firmware updates from your laptop’s manufacturer. These updates can address numerous hardware-related issues, including charging inefficiencies.
I’ve encountered similar problems, and it turned out to be a matter of BIOS settings. Enter the BIOS setup during startup (by pressing Del or F2) and inspect the power-related settings. Adjustments in these settings, like enabling a battery recalibration mode, could potentially resolve your problem. Another possibility is a malfunction within the laptop’s charging circuit on the motherboard. This is a more complex issue often requiring professional diagnostics and repair. Lastly, check out your Windows power settings; ‘USB selective suspend setting’ can sometimes interfere with charging operations and should be disabled to see if it helps.
From my experience, the issue might be due to a defective battery. Batteries lose their efficiency over time, and a deteriorating battery might need more power than the adapter can deliver, especially when the laptop is on. Try using your laptop without the battery to see if the behavior changes. Additionally, an update to your power management drivers might help. These drivers control how your device uses power, and updating them can sometimes resolve such issues.
One explanation for your PC’s peculiar behavior could be a faulty power adapter. Your charger might not be providing enough power to simultaneously charge the battery while powering the device. It’s worth testing with another charger that meets the specifications of your laptop. Verify that the voltage and amperage match those of your original adapter.
