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

The tools to disassemble this laptop is pretty simple:
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
Nicely done and well detailed. With assistance from your 'ible, which I do thank you for, I just finished disassembling a friend's Dell 1150 in order to re-solder the DC jack, which broke clear off the motherboard due to the laptop falling (back first) onto a hard floor - from table height. A replacement DC jack was needed due to broken and torn pins, and the disassembly, soldering, and re-assembly were ultimately successful but not so a successful bootup of the laptop - unfortunately. The power-on light turns on, the fan turns on but the screen stays blank, and I don't believe the HDD ever starts. At this point, I think it will only work as a parts reservoir and boat anchor. <br>QUESTION: Though unnecessary for the task of re-solding the DC jack, for kicks I removed the plastic frame (with the word &quot;DELL&quot; printed on the bottom) from around the front of the screen of the laptop, and noticed a small permanent magnet at the top (same location as the sliding latch mechanism that latches the laptop 'clamshell' together when it is closed). Do you have any idea what the magnet is used for? The clamshell latch is spring activated and is not affected at all by the magnet, so it is not there for the latch.
Glad that these instructions could help you. <br> <br>No I do not recall seeing a magnet the last time I took my 1100 apart, though that was a long time ago. I can not think of any resons as to why it would be there.
I think I had one of these awhile back, either this or the 1150.It was a great laptop, but It had a design flaw in which a tab on one of the back panels(I believe it was panel C) would press down on a chip, breaking it's solder leads, bricking the computer. it was my sister's laptop until it happened to her, then she gave it to me. after a little research I managed to fix it by first removing the tab that caused the trouble then pressing down on the chip with a small screwdriver and pressing the power button until it would work. after I managed to get it to turn on, I held the chip the way I had it and applied about two drops of super glue to it, creating an encasement that would hold the chip in place.
That must have been the 1150 because looking under panel C on the 1100, I don't see a black plastic tab. I do believe the 1150 had some design flaws when they first came out.
