This is a detailed tutorial on how to completely disassemble a Dell Inspiron 1100. I realize this is a very old laptop model but I have one which I use the most of my two computers. But with proper maintenence, any computer will run fine for many years to come. This tutorial will also work with the Dell Inspiron 5100 and 5150 series laptops as they are almost identical.
Step 1: What You Need
A Dell Inspiron 1100, 5100 or 5150 series laptop in need of disassembly
Thermal Grease (Not needed if you don't rip the processor off of the heatsink but it is recomended that the grease be replaced)
A Precision Screwdriver Set
A Pair of Plyers or a 3/16 Hex Adapter Thing
