Issue occurs when disconnecting the power adapter.
I own an HP G7-2294NR laptop that tends to crash when I unplug the charger.
It doesn’t shut down normally; it shows a blue screen after I disconnect the USB flash drive, forcing me to restart Windows with the keep my files option enabled. Once I got Windows updated and all drivers were clean, the yellow warning icon no longer appears.
My battery seems to work properly. The battery test confirmed ample capacity. However, as soon as I unplug the charger, the screen dims and then the blue screen appears. If I power off the laptop and restart without the charger connected, before reaching the sign-in screen, it still blanks with a confusing white mess and no readable text. Also, I’ve noticed that now the laptop tends to turn back on by itself after shutting down.
I have also replaced the battery and tried calibrating it, but it won’t start the calibration process.
What BIOS version do you have installed on your laptop's motherboard?
I needed to restart Windows using the keep my files option.
Instead of reinstalling the OS, I would have done it offline, then manually added all drivers with the newest versions while in elevated command, such as right-clicking the installer and selecting Run as Administrator.
HP usually needs replacement components from HP. These parts consist of chips to ensure this. I think your battery might not be fully compatible.
The bios version F.17 isn't accessible anymore since HP has stopped providing support, making it difficult to obtain the necessary device drivers for my laptop.
that isn't the main problem—it's that the HP battery might have varying voltages compared to non-branded ones. I think the battery, even if it has capacity, isn't getting the right voltage, which causes it to crash because the power isn't enough. The charger may charge it, but when plugged in, the laptop runs on the charger rather than the battery itself.
