  1. Last week a friend of mine gave me her Lenovo Laptop for cleaning. So I got this Lenovo V2000 Laptop from 2014 with following specifications: - Lenovo Lancer 5A5 Motherboard (Bios Ver. 9BCN29WW from 20th October 2014) [Northbridge: Intel Haswell-ULT IMC, Southbridge: Intel Lynx Point-LP] - Intel i7-4510U (2.0 to 3.1 Ghz, 15W TDP) - Nvidia GeForce 840M, 4GB Graphics - 1 TB WD HDD 5400RPM - Samsung DDR3 1600 8GB Ram - Windows 10 Home, Version 2004 which are quite ok for Zoom meeting and working purposes. So I opened the Laptop, cleaned all the dust, re-paste the CPU and GPU with Arctic MX-4 and changed the thermal pads on the VRAM. After all the cleaning I ran some benchmark (Cinebench R20 and XTU Stresstest) to test the machine, but I noticed the Laptop is working strange. The CPU temperature under load never go above 70 °C, and power usage stuck at max. 25 Watts, frequency keeps at 2.5-2.6 Ghz, never reached the maximum turbo boost frequency of 3.1 Ghz. So I downloaded Intel XTU and found out I can not raise the Turbo Boost Power Max above 25 Watts, the adjust bar maxed out at 25 Watts. So the CPU is always Power Throttling. I tried to look into the BIOS (InsydeH20 Rev 3.7) but I could find nothing which could relate to CPU performance, there's also no "ADVANCED" Tab. In ThrottleStop I could not change the maximum power settings also. Is there any method to solve this problem that could apply a higher maximum power to the CPU? Some friends told me I could use a 90w power adapter (65W now) or upgrade the HDD to a SSD which demand less power, but I don't think these are relevant to CPU settings.
