The black word knob on the notebook CPU can be screwed with a screwdriver?
Yes, but there are certain preconditions. For example, I used a notebook computer IBM T43 ago, just bought a 1.7 frequency Pentium (M) CPU, then check the Pentium, CPU (M) level of the highest frequency can be upgraded to 2.26G, a friend to help me get a change, the calculation speed and efficiency are a lot of upgrading. Therefore, the platform, level, maximum limit of these parameters must be noted. If you are not absolutely sure, you'd better not try, or ask professional staff to help you.
Although the whole view is not very clear, it is still basically possible to judge. The knob can be screwed with one word (one screw screwdriver). The concrete method is to turn left (Ni Shizhong) 90 degrees, and then push the pressure spring or shrapnel in the lower part to release the CPU.
