The Lenovo 3000 C100 comes in 2 models, one with a Celeron 1.5GHz CPU and Broadcom wireless chipset, and one with a Pentium 4 1.7GHz CPU and Intel wireless chipset. The model used in this article is the Celeron-based model. Both models have identical 15” LCD screens. | The Lenovo 3000 C100 comes in 2 models, one with a Celeron 1.5GHz CPU and Broadcom wireless chipset, and one with a Pentium 4 1.7GHz CPU and Intel wireless chipset.

In part one of this article, we covered the software side of setting up the Tweet Screen. In part two, we’ll cover disassembling and installation of the notebook in an 11” x 14” picture frame. I found the picture frame after visiting a couple of art stores. Having created a notebook picture frame several years ago, I knew it was important to have as much depth as possible to hold the notebook. Most art stores had frames with more than 1 inch depth, but the glass was often set almost at the back of the frame, rendering it useless. The frame I chose was 1 inch thick with the glass a few millimeters from the front. | In part one of this article, we covered the software side of setting up the Tweet Screen.

A number of years ago when I built the notebook picture frame, I made a couple of related mistakes: 1) I didn’t buy/build a frame big enough to hold the components of the notebook. 2) In further attempting to reduce the amount of parts in the notebook, I did not test the notebook enough during the second disassembly process. | A number of years ago when I built the notebook picture frame, I made a couple of related mistakes: 1) I didn’t buy/build a frame big enough to hold the components of the notebook. 2) In further attempting to reduce the amount of parts in the notebook, I did not test the notebook enough during the second disassembly process. | ||

Ideally, disassembly should be done on an anti-static mat. I didn’t have one handy so I used an anti-static strap connected to a metal ground. I had a large motherboard anti-static bag handy, but since I only ever exposed the screen and the front bezel above the notebook keyboard, it really wasn’t necessary. | Ideally, disassembly should be done on an anti-static mat.

Disassembly started with taking out the battery and DVD-RW, then testing to make sure the notebook powered on. The Lenovo 3000 C100 has a slide switch that conveniently pops out the battery. Removing the battery eliminates heat and lessens the weight of the entire unit. The DVD-RW is held in by a small, F3, single screw. | Disassembly started with taking out the battery and DVD-RW, then testing to make sure the notebook powered on.

Most of the screws on the bottom of the unit are either of the F3 (short type used to secure the memory lid, hard drive, screen, and DVD-RW). or F6 (longer type used to keep the case together). Only two other longer screws securing the screen base to the notebook were removed at a later stage. I kept the screws organized on a couple of long stickers marked F6 and F3, and later deposited these in an inexpensive plastic sorting box I bought at a dollar store. | Most of the screws on the bottom of the unit are either of the F3 (short type used to secure the memory lid, hard drive, screen, and DVD-RW). or F6 (longer type used to keep the case together).

The next job was to remove the casing from the screen. While this is one of the thinnest parts of the notebook, the latch at the top which secures the screen to the notebook when closed would make it impossible to lie the screen flat on the glass. Most laptops have stiff round plastic covering a number of screws. In the case of the 3000 C100, there were 6 small F3 screws hiding behind the plastic cylinders. I used the smallest slot head to pry up the plastic cylinders then used a small Phillips screwdriver to remove the screws. | The next job was to remove the casing from the screen.

After removing the front panel plastic from the screen, I noticed a couple more screws securing the wireless antennas to the top of the screen. At the bottom of the screen lay the screen inverter. I carefully removed the tape securing the inverter to the back of the case, then unscrewed the antennas and removed the plastic LCD backing. | After removing the front panel plastic from the screen, I noticed a couple more screws securing the wireless antennas to the top of the screen.

Just after removing the back plastic portion of the LCD case, look at the back of the LCD. On the back of the Lenovo 3000 C100 screen is tape cautioning not to touch the backlight portion near the top of the LCD. Of course I had already touched it without realizing, so at this point I powered on the notebook and tested again - thankfully it booted. Note that the backlight electronics were covered by a thin film of plastic, but they might not be on all notebooks. | Just after removing the back plastic portion of the LCD case, look at the back of the LCD.

- | With the screen detached from the metal rods, the next job was to secure it on the back/bottom of the notebook. But before attaching the screen, I peeled a thin film of tinfoil-like metal off the back plastic LCD panel. This metal film acts as an anti-static shield. I carefully removed the metal foil and attached it to the bottom of the notebook, taking care to cut out a small square to vent the memory area. Much of the stickiness of the foil had stuck to the back plastic panel no longer in use, so I used electrical tape to secure the foil to the bottom. I also used electrical tape to secure the screen to the plastic base of the notebook, taking care not to cover too much of the screen or leave metal exposed. | ||

With the screen on the opposite side of the keyboard I now tested the unit once again. This time shutting the unit down via keyboard and trackpad proved quite difficult, even with a mirror. Happily I had already set up a static DHCP reservation for the machine, and installed SSH so I remotely shut it down over SSH. | With the screen on the opposite side of the keyboard I now tested the unit once again.

At this point, I had a bit of the inverter wire inconveniently placed at the top. Normally this wire is channeled into the LCD screen, but it proved to be quite helpful in the end adding a few extra millimeters so that the top and bottom fit snugly inside the picture frame. This left a gap just shy of 1 centimeter on each side of the frame. | At this point, I had a bit of the inverter wire inconveniently placed at the top.

With the notebook in the frame I marked off an area of ventilation at the bottom and the area the power core was to plug into the system. With this done I removed the notebook and cut out the marked off areas. I’d love to claim that I did this expertly, but the truth is I used what I had at my disposal, a junior hacksaw and a dremel. | With the notebook in the frame I marked off an area of ventilation at the bottom and the area the power core was to plug into the system.
