Can't get cover off laptop to replace fan

Check to make sure your blades screws are tight. They could be rubbing against the glass.

Instructions

Shut down your Toshiba laptop, and then disconnect all cables. Close the LCD lid, and then place the laptop face down on a flat surface. Position the laptop with front edge facing you.

Locate the battery pack near the top section of the laptop's bottom casing. Press on the battery release button. Remove the battery from the laptop.

Locate the cooling fan compartment cover. Its location varies from laptop to laptop, but it will be the only hardware cover with a vent in it. Remove the Phillips-head screws securing the fan's cover in place. Remove the cover from the laptop.

Disconnect the fan's cable from its connector on the motherboard. Remove the Phillips-head screws securing the fan in place. Lift the old fan out of the fan compartment and set it aside. Removing the old fan will reveal the processor chip. Apply a thin coat of thermal grease to the processor's surface using a clean paper towel. This will prevent your new processor from frying once you power on your laptop.

Place the new cooling fan assembly inside the fan compartment. Align the screw holes on the new fan with the screw holes inside the compartment. Replace the four retaining Phillips-head screws, and then reconnect the fan's power cable to the motherboard. Replace the fan compartment's plastic cover, and its retaining Phillips-head screws.

Replace the battery pack and reconnect all power cables and external devices. Turn on your laptop to test the new cooling fan

Laptop hinges are generally made of low-cost metal alloys, or "pot metal yeah this may cause problem you can fix your broken hinges easily by spending little time ." Pot metal is not particularly durable, and over the course of a laptop's life cycle, repeated opening and closing of the computer's lid can cause wear that prevents the lid from staying in an open position. Hinges can also wear to the point that they break at the point of attachment, either on the lid or the computer's body.

Hinges are usually attached to the computer's frame via machine screws. In order to get the most life out of your computer's hinges, it is not a bad idea to perform a yearly inspection. Remove the hinge covers and check that the machine screws that secure the hinges are tightened fully. If screws are missing, contact the computer's manufacturer to order replacement screws; hinges missing screws are subjected to additional stress and can wear out faster if steps are not taken to replace the screw.
Lubrication of the hinge is possible, but not recommended; if the wrong type of lubricant is used, it could damage the computer's case or seep into the electrical components and further damage the computer. Consult a professional technician if you feel that your hinges require lubrication.

o Hinges can also be damaged when the computer is picked up by its lid, dropped from various heights or opened beyond the angle at which it should stop. In these situations, damage to the hinges may be of secondary concern, as component damage and data loss might have occurred. Depending on the amount of damage and warranty status, the computer may require complete replacement.

Laptop hinges are not indestructible, but their coverings and trim may show wear long before the hinges are actually in any danger of failure. Most laptops on the market include plastic hinge covers. The hinge covers can develop stress fractures from repeated wear; most of the time, this is not indicative of a hinge problem.
Some laptop hinges are housed within the bezel or trim of the computer's monitor or body. This, too, is generally made of plastic, and might develop stress cracks after a few years of use. Hinge covers and bezels are usually modular, and replacements are generally easy to find at low to moderate costs.

Repair

o Hinge problems can be mitigated with adjustments to the hinge's tension or additional hardware installation by the user. Brackets can be installed on the outer case to allow for hinge-like performance, or the screen can be mounted in a fixed position. If the screen is left permanently open, care should be taken to prevent damage to the screen and to prevent dust accumulation in the keyboard.
The lid and screen assembly can also be replaced, if the correct parts can be found. Replacement of the lid and screen can be cost-prohibitive, with parts and labor sometimes exceeding the cost of the computer.

A laptop has become a very convenient and mobile way to stay connected with work, to communicate with peers, to research, to take notes and to do just about anything related to computing. However, when the convenient laptop gets noisy, it is an irritation to everyone. The noise maker in a laptop is almost always the fan, and it can be fixed by cleaning or replacing.

1.Unplug the laptop and remove the battery. Of course, you don't want to do this until you have shut down any programs that were open and shut down your computer normally. Be on the lookout for static electricity--don't touch other electrical devices while you are doing this and touch something metallic to discharge any static from your body before toughing the inside of the laptop.

2.Remove the screws that cover the back of the computer. This will differ from laptop to laptop, depending on your make and model. Set the screws aside and lift the cover off. You should be able to see the small square fan that cools your laptop. If you have had your computer running for a while, there may still be some rather hot components, so be careful.

3.Inspect the fan for a buildup of dust. If you can see obvious debris in the way, use a small vacuum hose to **** the dirt out of the area. Be very careful not to get too rough, as the inside of the laptop is fragile.

4.Remove the fan if there is no obvious buildup. This usually means unscrewing it and undoing the wiring. Write down the information on the fan such as the part number and serial number to order a new one. You may find one in your local computer parts store.

5.Install the new fan in the reverse order of how your removed the old fan. Screw everything back together and put the back cover on. Replace the battery pack and plug the laptop in. The new fan should run smoothly and quietly.

I hope it helps.

The missing screws should have no affect on whether or not it turns on. Try to ensure that all the ribbon cables are properly secured in the correct locations.

Basically what you need to do is remove the screws on the bottom of the laptop. Beware that there are usually screws under the covers for the hard drive and memory and such. Also there are usually screws under the CD drive which has to be removed before the top cover can be removed. Most times it is favorable to remove the monitor by removing the hinge screws and wires from the main board. Also note that all the plastic covers also have snaps so some force must be used to separate the covers.

Best of luck, Jim
