[ltp] How to turn your T42p into a brick with ACPI...

[Dragos Vingarzan]

As the Hardware Maintenance Manual states, the screws should be used 
only once as they are supposed to be nylon coated - this helps to 
tighten the grip they have and they don't come loose with time. After 
one usage, the nylon is damaged so you should use new ones. Oh, and 
don't compensate for that by over tightening them - you will damage 
important components extremely easy - trust me :( !!! Each screw has 
different tightening forces, depending on what they tight - look for it 
in the HMM. I know that event the IBM approved services don't really 
follow this recomandations, but then, it's your laptop. For example they 
changed a motherboard for me 3 times and never replaced a screw...

If you don't replace them, you laptop will make "cheap" noises when you 
move it....
But I was wondering what should you do when you change some customer 
replaceable components like the keyboard or memory under the keyboard... 
IBM should have provided some spare screws for that ;-) - as they do 
with the one for the ultrabay locking.

Cheers,
Dragos
