Hey everyone! Before I go into more detail here are my computer specs:
Laptop: Lenovo Y40-70
Processor: Intel(R) Core(TM) i7-4510U CPU @ 2.00GHz 2.60 GHz
RAM: 8 GB
OS: Windows 10 Home 64-bit (upgraded from Windows 8.1)
Graphics: AMD Radeon R9 M275
-RAM: 2 GB DDR3
-Core Clock speed: 925 MHz
-Memory clock speed: 1000 MHz
-Total Memory bandwidth 32 GB/s
So here's the problem: When running on battery, if I boot/restart my computer above 40% battery, when it reaches below 40% battery it maxes the CPU at 30% speed, resulting in it running very slow. If I reboot when it is under 40% battery, it then runs like normal and won't cap the CPU until I tell it to or reboot again when it is over 40% battery. This problem does not exist if the AC adapter is plugged in.
I checked the BIOS and found that all my P-states are set to max performance. In my battery settings I have the minimum and maximum CPU processor speed set to 75% and 100%, respectively, on battery. I tried changing the values but nothing seems to change this peculiar behavior.
I've also had the battery replaced recently since the old one was bad, but that wasn't the cause of the issue as it's been happening before that. It has also happened before the upgrade to Windows 10.
Any ideas? Thanks in advance!
