читал руководство по обслуживанию IBM Thinkpad
«ThinkPad Computer Hardware Maintenance Manual» — настоящая «rocket science». С таким подходом можно космические ракеты делать.
Кстати, оказывается, при любой сборке-разборке thinkpad:
Do not try to service any computer unless you have been trained and certified. An untrained person runs the risk of damaging parts.
Information on Engineering Change Announcements (ECA) are stored in the EEPROM of the system board. The electronic storage of this information simplifies the procedure to check if the ECA has been previously applied to a machine.
Screw notices:
Loose screws can cause a reliability problem. In the ThinkPad computer, this problem is addressed with special nylon-coated screws that have the following characteristics:
Each one should be used only once.Do the following when you service this machine:
Keep the screw kit (for the P/N, see “Miscellaneous parts” on page 243) in your tool bag.
Always use new screws.
Use a torque screwdriver if you have one.
Tighten screws as follows:
Plastic to plastic:
Turn an additional 90 degrees after the screw head touches the surface of the plastic part: 90 degrees more(Cross-section)
Logic card to plastic:
Turn an additional 180 degrees after the screw head touches the surface of the logic card: 180 degrees more(Cross-section)
Torque driver
If you have a torque driver, refer to the “Torque” column for each step.

Наверное, любую обезьяну, умеющую читать, этому обучить можно.

Loose screws can cause a reliability problem. In the ThinkPad computer, this problem is addressed with special nylon-coated screws that have the following characteristics:
- They maintain tight connections.
- They do not easily come loose, even with shock or vibration.
- They are harder to tighten.
