Re: UEFI -- No bootable device found in Acer Aspire 3 A315-21-4808 laptop with Windows 10 (64-bit) version
Hi Hugger1
The Aspire 3 A315‑21‑4808 is limited by its 2016 AMD A4‑9120 platform and the last BIOS version 1.25 (June 2020). That firmware baseline does not include updated AGESA microcode for newer Windows 10 builds. Because of this, Windows 10 22H2 drivers will fail under UEFI mode and only boot in Legacy mode.
To avoid instability, forget about 22H2 and install a legacy Windows 10 release that matches the BIOS support window — for example version 1909 (Nov 2019). This build is fully compatible with BIOS 1.25 and avoids the AGESA driver issues seen with 22H2.

Re: My laptop acer nitro 5 an517-54 crash game when plugged in
Hi yyyanhkhoa
Installing Windows 10 is unlikely to resolve this issue. The symptoms point to a hardware fault in the power rails module rather than a software or OS problem.
Please take the laptop to an Acer endorsed repair shop so they can check the power rails circuitry. This type of fault requires professional diagnosis and repair, and attempting software fixes will not address the underlying hardware issue.

Re: Uninstalled Predator Sense and it won't let me reinstall it. I have a Predator PH315 - 52
You need to install the PH315-52s exact Predator Sense Application last version: 3.00.3136 from this location HERE, otherwise it will not install or work. Do that as it should work 100%. First make sure that all PS apps are uninstalled through Control Panel > Uninstall a program and then reboot the computer and install the above PS version, so do that and let us know how it worked out.

As noted earlier, wait for a BIOS update.

Re: PHN16-72-Is the battery calibration worth it?
No, just once every 3-4 months, drain your laptop battery from 100% to 5%, then recharge it to 100% and continue using it while plugged in.
Additional info you may need:
Gaming laptops are completely safe to remain connected to the power source once they reach 100% charge. Gaming laptops such as Nitro Series and predator Series come with a battery management system that bypasses the battery by supplying power to the laptop directly from the charger if it has already been fully charged.
It is recommended to keep the battery at 100% and plugged in for optimal battery health. Lithium-ion batteries have a limited number of charge cycles, so frequent discharging and recharging reduces their lifespan faster. Users who want to run the laptop on battery power can do so, but should not do it frequently and must avoid letting the charge drop below 20%. Some people also perform battery calibration, draining from 100% to 5%, then recharging to 100% and continuing use, once every three months to maintain accuracy.
Re: PHN16-72-Is the battery calibration worth it?
Hello kbruff2026,
“Battery calibration” is a misnomer. What it actually refers to is the one full charge cycle required only once after a new battery is installed or after Windows has been reinstalled/reset. This cycle registers the full charge capacity in BIOS and the Microsoft ACPI Battery protocol.
- On a new laptop, Acer already performs this cycle at the factory, so it’s not needed.
- I don’t recommend using Acer Care Center or PredatorSense “Calibration/Optimization/80% charge limiting” features — they don’t extend battery life and can interfere with ACPI drivers.
If you reinstall the battery or upgrade Windows, here’s the correct one‑time procedure:
- Disable Fast Startup in Windows Power Options.
- Update BIOS if available.
- Charge the battery to 100% and wait an extra 10 minutes.
- Unplug the adapter and use the laptop until it shuts down on its own (do not suspend or manually power off).
- Close the lid — data will be safe.
- Plug in the adapter and charge until the amber LED turns blue, then wait a few minutes.
- Boot back into Windows.
That’s it.

Re: What causes performance drops over time without heavy usage?
Top Likely Causes
- Thermal Throttling (Hardware): Laptops accumulate heat over time. As components (CPU/GPU) reach high temperatures, they reduce their clock speed to prevent damage, causing sluggishness.
- Memory Leaks (Software): A program or driver might not be releasing memory back to the system, causing RAM usage to slowly grow over hours until the system uses the much slower storage drive as virtual memory.
- Background Maintenance Tasks: Windows often triggers updates, security scans (Windows Defender), or file indexing when the system is idle or has been on for a while.
