Remove the four Phillips screws located on either side of the rear of the T42 (there are two on each end.)
leave these four screws alone. No need to remove them.
There are tiny numbers showing the lengths of the screws. 1-2-3-4 where 1 is the shortest.
The dark red circles are not very easy to see. How about white ones?

Get the HMM for the laptop! On a few of these, I have had to just pull out the internal wi-fi card, and use a USB wi-fi adapter.
The only screws that need to be removed are the ones that are numbered 1-4 on the bottom of the case. Best to remove the screws with #4 next to them, then remove the keyboard and then remove 1-3 and then the palm rest. Removing the ones on the rear is unnecessary.
