When planning to upgrade your laptop’s memory, first ensure that you have compatible memory by using an online parts locator tool. It is recommended that you install the maximum amount of RAM that your laptop will support to ensure you get the maximum performance boost possible. Once you have your new memory modules, follow these steps to upgrade your laptop’s memory:

1. Power down the laptop and disconnect all cables, including the power cable. Remove the battery pack by releasing the latch and tilting the battery toward you.

2. Close the laptop lid and flip it over to look at the bottom of the machine. Locate the memory access panel, usually located in the center and marked by an arrow. Remove the screw securing the panel in place and remove the panel.

3. You will see the top memory module. Push the two retaining clips out toward each side and the module will tilt up. Gently pull the module out of the slot. Repeat with the second module if necessary.

4. To install the new module, line up the pins and notch with the slot and gently press the module in place, then press down to lock it into place.

5. Replace the access panel and the retaining screw.

Once this is finished, replace the battery, reconnect the power cable, and power up the laptop. Test to ensure that all of the new memory is recognized by the operating system, and you are finished.

The first step is to find a replacement part. Many online retailers provide a parts locator tool that allows you to find parts for your specific model. This ensures you have a compatible part that will be a direct replacement.

Once you have the replacement keyboard, follow these steps to perform the repair:

1. Power down the laptop, unplug the AC adapter and all cables, and remove the battery. This reduces the risk of electric shock while repairing the laptop.

2. Locate the plastic bezel above the keyboard. It is a bar located above the function keys. Close the laptop’s lid and flip it over to the bottom. There are two screws directly below the bezel, holding it in place. Remove these two screws.

3. Flip the laptop over and open the lid. Gently pry the bezel with a credit card or other object by placing it between the bezel and the screen and prying it upward. Remove the bezel and set it aside.

4. Slide the keyboard up and away from the touch-pad. It is connected on the underside by a ribbon cable. Disconnect the cable before removing the keyboard completely, and note the location of this connector. Remove the cable connector by pulling on the two tabs very gently, and then remove the keyboard.

5. Put the new keyboard in place, and lift it up to reconnect the ribbon cable. Lock the connector tabs in place, after that snap the keyboard back into the machine.

6. Replace the plastic bezel and snap it into place, then flip the laptop over and replace the two screws holding the bezel in place.

7. Replace the battery and reconnect the AC adapter cable, power up the laptop, and check that the new keyboard is functioning properly.

Assuming everything is working correctly, you are finished. You can now enjoy your new keyboard and the satisfaction of a job well done.

1. Overheating

Almost every laptop will heat up somewhat under heavy use. In most cases, you will hear the fan begin to spin faster and make more noise when this occurs. If your laptop begins to get excessively hot and the fan does not appear to be spinning faster, it may be failing.

2. Strange noises

If you hear strange whining or grinding noises, the source could be a failing laptop fan. In some case, the bearings of a fan wear out or lose their lubrication, and the result is a noisy or grinding fan. You should replace it immediately.

3. Laptop locking up

If your laptop freezes or locks up, especially when performing a processor-intensive task, it could mean a laptop fan failure. Excessive heat is one of the primary causes for computer freezes. If this problem persists, try replacing the laptop fan.

4. Fan keeps running

In some cases, the laptop fan may continue to run and run at full speed, even when the laptop is not hot enough to warrant it. This can also be a sign of a failing fan, as it is not responding to the laptop’s signal to lower the fan speed.

Replacing a laptop fan can be a simple job or a very complex one depending on your laptop model. Some fans are easy to access, while some require a lengthy disassembly process. You can check around in search engines for replacement instructions specific to your model to take some of the mystery out of replacing your laptop fan.

The process for removing and replacing a Sony laptop keyboard varies for different models, so it is best to use a service manual for specific instructions. Often, you can find a service manual by searching online for your laptop’s model number and the term “service manual”. It is also highly recommended that you use an anti-static wrist strap when disassembling a Sony laptop, to reduce the risk of damaging sensitive components.

Here are some guidelines for the basic steps involved in replacing Sony laptop keyboards on most models:

1. Shut down the laptop and unplug the AC adapter.

2. Remove the screws from the bottom of the case, and pry the top and bottom half of the case apart carefully.

3. With some models, you will have to remove the LCD screen as well, so remove the screws holding in the screen and disconnect its ribbon cable.

4. Remove the top of the case and you should have access to the keyboard. There may be a few screws to remove, then slowly pull the keyboard up and forward. Disconnect the small ribbon cable under the keyboard and pull it out.

5. To install the new keyboard, connect the ribbon cable and reverse the disassembly process to reassemble the laptop.

6. Reconnect the battery and AC adapter and power up the laptop to test that the new keyboard is working. If so, you are finished.

While most desktop hard drives are in the standard 3.5″ form factor, nearly all laptop hard drives use the 2.5″ form factor. While other standards are sometimes used in the smallest laptops, the vast majority of laptops use the 2.5″ hard drive standard.

There a few factors related to the speed of laptop hard drives. The first is the spin speed of the platters in the hard drive which store the data. The most common speed for laptop hard drives is 5400 rpm (revolutions per minute), but 4200 rpm and 7200 rpm drives are also common. Generally, the faster the rotation speed, the faster the access time for the hard drive, but a drive with a faster rotational speed will consume more power and will be more noisy during operation. These are reasons why many laptops have 5400 rpm drives instead of the faster 7200 rpm drives. The actual speed of the drive is usually measured in “access time” or data transfer rate. These ratings give buyers a comparison for which drive may perform better.

Most modern hard drives connect through either SATA or PATA (IDE) connections. PATA uses a large ribbon cable for connecting to the motherboard, and was the most common drive connection technology for many years. SATA, or Serial ATA, is a faster connection method, which also uses a smaller port and cable than PATA, making it ideal for the tight spaces of a laptop. SATA offers better access speeds than most other technologies.

A new laptop hard drive technology is emerging, called solid state, which uses flash memory instead of platters. The lack of moving parts results in lower power usage and often faster access times, but the cost of solid state drives is very expensive. As prices come down in the future, it is likely that solid state drives will become the most common technology for laptop hard drives.

Another precaution for replacing system boards in Sony laptops is get a professional analysis of the device. Often, a motherboard with apparent malfunctions can simply be caused by a BIOS that is not up-to-date. The BIOS and the system board for Sony laptops work in sync with each other, to maintain the devices proper functionality. To inspect the BIOS system before replacing Sony laptop motherboards, utilize the support website of the BIOS manufacturer, to research the most recent updates for each unit.

Excessive heat is biggest complication with all electronic devices, and is one of the leading causes of Sony laptop motherboards becoming damaged. Although it is difficult to prevent, overheating notebook’s should be carefully attended to. Users are recommended to place their notebook on a flat neutral surface, to avoid the combination of body-heat and the heat generated by laptop, from raising the Sony laptop motherboard’s temperatures above a safe level.

System boards for Sony laptops may also be overheating due to blockage of the ventilation area. This areas is usually located on the back or side of the device, and emits the hot air being produced by the Sony laptop motherboard. It is immensely important, not to block the cooling fan, and to clear it of any dust before operation. To minimize system board temperatures for Sony laptops, many users purchase an external cooling fan, placed underneath the notebook.

The next step to replacing Toshiba laptop hard drives, is to unscrew and remove all screws and covers from the bottom of the notebook. This includes the hard drive and the memory bay covers. There may also be additional screws located under the battery pack, that must be removed when replacing Toshiba notebook hard drives. When the screws on the back of the Toshiba laptop are removed, the device can now be flipped over.

Begin removing the keyboard bezel, and carefully remove the unit. When the keyboard bezel is removed, the next step in replacing hard drives in Toshiba laptops is to remove all the visible screws, securing the keyboard unit. Carefully lift the keyboard and place it on the palm rest, being mindful of the ribbon cable attached to the motherboard. The panel wire and keyboard cable underneath the unit, are easily disconnected, releasing the keyboard unit from the laptop.

After the keyboard is released, the final steps to replacing a Toshiba notebook hard drive include removing the remaining video and speaker cables. Finally the Toshiba laptop hard drive can be unscrewed and removed from the device. The new hard drive can now be inserted, and the device reassembled. It is highly recommended to take pictures, of the entire Toshiba notebook hard drive replacement procedure, to use as a visual reference during reconstruction.
