Cmos battery is new

Turbo boost does not work without a laptop battery, the power supply is new standard 65w, with the old one there are frequent drops in Skyrim due to the transfer of power to the battery in less than 2 minutes, the unit did not even have time to heat up, is it possible to buy a 90 watt one?

Windows 10 is clean, BIOS is reset, if you connect the battery, turbo boost works, but in games sometimes it changes the power supply system to the battery, fps drops occur, not significantly for a long time 3-5 sec in Skyrim graphics on high, without ultra, extremely rare in NFS most wanted, detroid become human on low everything is fine with the temperature everything is fine the cooler is turned on at maximum, the laptop is on a stand video card, maximum temperature 65, hotspot 73, processor maximum temperature was 83

standard 73-76, battery indicator lights up, wear 25-30%

Problem with the keyboard, turns on with any button except power, press the key, hold, put a toothpick and everything works

Hi Moshass82,

On the Aspire 5 A517‑51G‑53MB, what you’re seeing is normal for this model’s hybrid power design. It will still boot and run Windows on AC alone, but full performance — both at the BIOS level and inside Windows — requires both a working AC adapter and a healthy main battery.

Here’s why:

1. AC adapter supplies the steady baseline power.
2. Battery acts as a buffer for short, high‑draw bursts (e.g., Intel Turbo Boost, GPU boost states) that exceed the adapter’s instantaneous capacity.
3. Without that buffer, firmware limits kick in — CPU stays at base clocks, and certain boost functions are disabled to prevent instability.

So it’s not a fault with your unit, In this model, the battery is part of the power delivery system by design, and removing it means you lose that extra headroom for peak performance.

If your goal is 100% performance, you’ll need both a good battery and the correct‑wattage adapter. A higher‑watt adapter (e.g., 90 W) may reduce how often the system draws from the battery under load, but it won’t bypass the hybrid logic in firmware.
