Before I start working on any laptop or notebook computer I remove the battery. Don't assume the LCD is bad just because you can't see anything on the screen. The battery on our Apple PowerBook 180 releases with a slide button on the side, just like and old Toshiba notebook, then pulls right out. Before continuing on to replace the LCD screen, it pays to do a little troubleshooting. If the screen is cracked, has annoying dead pixels or a complete row or column is out (IC driver failure), it's time to replace the LCD. On the other hand, if the laptop screen is totally dead, it's more likely the video integrated on the motherboard, so at least test the laptop with an external monitor before proceeding.
Most laptop screens come apart the same way, starting with a couple of screws hidden by rubber cups near the hinges. The rubber cups serve a double purpose, hiding the screw and providing a bumper stop when the notebook screen is closed. This PowerBook 180 is assembled with torx screws, but you don't really need the special tools to dissemble it. I use a small jewelers screwdriver on baby torx, the standard, not the Philips which can actually damage the screw head.
The actual LCD screen is installed within a wide plastic bezel, which can be lifted right off after removing the two screws. The bezel is hinged at the top on plastic tabs. The screen is wrapped around the sides and back with a metalized foil to reduce RF interference. You can see the opposing springs on the bottom hinge that keep the laptop screen in place when you adjust the tilt.
Laptop screens are manufactured by third part LCD manufacturers, who may also supply all of the control electronics for the screen. This Sharp LCD is held in place by four screws at the corners. The power comes in at the right (white wires) through the right hinge, and the video signals come in on the flat ribbon cable through the left hinge.
There are at least three different connector technologies used with ribbon cables in this PowerBook 180. The video connectors are simple push-ins without latching, but there is a lip on the connector that gives you and easy way to remove it without pulling on the cable. The ribbon cable connector on the back of the LCD screen is easily removed by twisting a flathead screwdriver between the connector and the lip on the ribbon cable.
You want to know how to install a laptop screen? Exactly the same way as you remove it, very few tricks. The LCD power connector is the last connection to make, after the video cables on the back are in place and the LCD is secured with four screws. All that's left is to replace the plastic bezel, which turns the laptop screen into a monitor:-) The final step below, before the bezel snaps into place, is making sure the wires and in this case, the ferrite slug, won't get pinched. The finishing touch is restoring the little rubber bumpers over the screws, a little shock absorption for when the laptop screen is folded down over the body for carrying.

One of the first laptops with Intel's new Core Duo processor to hit the street, the Dell Inspiron 9400 inaugurates the company's new entertainment line of laptops with a bang. In addition to its top-shelf processor and graphics card; its bright, 17-inch widescreen display; and other leading edge technologies, the Inspiron 9400 adds a few welcome multimedia features not found on the model that it will eventually replace, the Inspiron 9300. These include a five-in-one media card reader and Dell's MediaDirect software, though there is no integrated TV tuner. We think the slightly less expensive HP Pavilion dv8200 is a better deal for basic users who want more features than performance, but the Inspiron 9400 owns the other end of the spectrum as an incredibly powerful laptop that can speed through virtually any multimedia task from video editing to gaming.
Design
The Inspiron 9400's design is nearly identical to the Inspiron 9300's. Crafted out of sturdy and stylish magnesium alloy and measuring 394 x 288 x 41.5mm. Our test unit weighed 3.6kg (4.2kg with its AC adapter) -- 100g lighter than the HP Pavilion dv8200. Still, the Inspiron 9400 is too heavy for regular travel.
The Inspiron 9400 includes a full-size keyboard, though it lacks a separate number pad, as found on the HP Pavilion dv8200. The Inspiron 9400's mouse buttons are very big, however, and the touch pad is adequately sized. The latter features arrows running along its right and bottom edges, outlining where to place your finger when using the software-enhanced pad to scroll through documents or Web pages. Features
A minor but appreciated upgrade from the Inspiron 9300 model is the Inspiron 9400's inclusion of Dell's MediaDirect software, which plays CDs and DVDs and lets you access photos and other media files stored on your hard drive without booting up Windows first. The two speakers and the internal subwoofer -- a rare feature among laptops -- deliver crisp and rich sound. Better yet, because the speakers sit in the corners of the laptop's front edge, your hands won't muffle them while you're typing and you can play music with the lid closed. Sandwiched between the speakers, a row of seven buttons lets you control disc playback and adjust or mute the volume. However, the Inspiron 9400 lacks an integrated TV tuner found on more expensive systems, such as the Toshiba Qosmio G20 and the Fujitsu LifeBook N6210. Our Inspiron 9400 test unit had a bright, vast, 17-inch widescreen display with a superfine WUXGA 1,900 x 1,200-pixel native resolution. Though we experienced no problems with our unit's display, we've observed many user complaints about other recent Dell models' screens. There's no dearth of ports, jacks, or slots here: The Inspiron 9400 offers FireWire, S-Video out, VGA, a whopping six USB 2.0 ports, 56Kbps modem, 10/100 Ethernet, headphone and microphone jacks. Also available are Type II PC Card and Secure Digital slots and a swank DVI port should you want to connect the laptop to an even bigger digital LCD. There's also a five-in-one media card reader, a key feature that the Inspiron 9300 lacked. Last, but definitely not least, the Inspiron 9400 includes a multiformat double-layer DVD drive. Performance
Like all of Dell's laptops, the Inspiron 9400 is extremely configurable. Our loaded, test configuration was equipped with a new Intel Core Duo T2500 (2.0GHz) processor; 1GB of DDR2 667MHz SDRAM; an 80GB, 5,400rpm hard drive; Nvidia's high-end GeForce Go 7800 GPU with 256MB of dedicated video memory; and a nine-cell battery. One of the first Core Duo systems we've tested, the Dell Inspiron 9400 did not disappoint. Using a collection of multithreaded and single-threaded multimedia applications, we tested the Inspiron 9400 to determine how well it handled multimedia workloads, such as ripping MP3 and encoding video. Generally speaking, the Inspiron 9400 delivered roughly a 25 per cent performance boost compared with a Pentium 4-fueled test system, the Acer Aspire 1700, and its performance was approximately 50 percent faster than that of a ThinkPad Z60t equipped with Intel's previous generation 2.0GHz Pentium M processor. The Inspiron 9400 also delivered very competent gaming performance, turning in 57 frames per second in our Doom 3 test. That said, the Acer TravelMate 8204, outfitted with the same processor but twice the RAM, bested the Inspiron 9400 in a few of our multimedia tests and posted the highest SysMark score we've ever recorded, though its gaming performance was lacking. Though we did not test an Inspiron 9400 configured with the less expensive Core Solo processor, Dell said that its performance would be comparable with that of an Inspiron 9300 loaded with a Pentium M, a configuration that we tested last year. Dell offers a one-year next business day onsite warranty which covers parts and labour. The company's support website contains a knowledge database for basic troubleshooting and downloading of updated drivers. Optional warranty options include extended three-year warranty, HelpDesk, onsite service during nights and weekends, and Plus Phone support can be purchased together with the system. Plus Phone support extends the technical phone support to include Saturdays. HelpDesk coverage provides 24-hour phone support from an expert who can help with any problems related to Dell hardware and peripherals and even some third-party software from major vendors, such as Microsoft Office.
