How To Take Apart a Gateway Laptop
The first step in fixing any internal problem in your Gateway laptop is disassembling the base unit and motherboard completely. You will need to do this as well if you want to clean its fans, replace the adaptor for wireless network connections, and upgrade its memory. Having these processes done by a certified technician can cost you a lot of money. However, if you have a little hardware knowledge, a few basic tools, and a few hours to spare, you can easily take apart your Gateway laptop on your own. Just follow these steps.
Prep the laptop before taking it apart. If your laptop is switched on, shut it down and wait for it to cool down before unplugging the adaptor. Turn the unit over and remove the battery pack. Lay the laptop down on a flat and dry surface. Position the unit so that the hard drive is at the corner, bottom left side and the slot for the battery is at the far side. Prepare several marked dry containers for your screws.
Detach the covers of the hard drive and the memory board. Locate the two screws securing the cover to the rest of the unit. They should be found on the cover’s left side. Use an appropriate screwdriver to remove these and detach the cover completely by lifting it off the laptop’s base. Now that it is off, you should be able to see the cover of your laptop’s memory board. There should be eight screws securing it. If you are having a hard time finding this, just look for the product sticker marked Gateway and look at the area above it. Again, use the correct screwdriver to get these securing pins loose.
Disconnect the adapter for the wireless network connection and the pair of memory modules in your Gateway laptop. Locate the cover right above your laptop’s hard drive. Take off the cover of the Wi-Fi card by undoing the screw holding the adapter in place. You should see two cables attaching the adapter to the wireless card. Simply disconnect these cables then snap the wireless card out of its holder. You will find the memory modules in the middle of your motherboard. With your fingers, pull them out and place them in a safe area on your table.
Remove the heat sink and CD or DVD drive. Find the screws holding your CD or DVD drive to your unit. There should be about four of these screws. Unscrew them carefully and gently push the drive out of the slot. Find the unit’s cooling fan and locate the heat sink. Unscrew all four of the tacks securing the assembly and gently lift the heat sink and fan out. You will see a cable connecting the fan to the laptop, firmly unplug this cable.
Remove the remaining covers. You will find eighteen screws around the base of your Gateway laptop. Look between the product stickers and at the center of the board. Remove the screws and place them inside your marked container. Stand the laptop on one of its edges with its back facing you. You will find two more screws securing the hinges. Remove these screws then pry hinge cover up. Gently lift this cover off.
Detach the laptop’s keyboard and LCD screen. Lift your laptop’s keyboard and gently release the data cable connecting it to the motherboard. Unplug the cables for the Wi-Fi antenna and video. Unscrew the bolts on either side of the LCD screen. You should now be able to lift this off the base unit.
Finally, you can disconnect the system board. Just flip over the base unit and remove the five screws securing the system board. Unhook the data cable attaching it to the base.
Now that you have completely taken apart all the components of the Gateway laptop, you will be able to perform any of the upgrades and repairs that you need to do. Just remember that if your unit is still under warranty, do not open your laptop or else the warranty will be voided.

How To Take the Keys Off a Laptop
Have you ever been stuck in a situation where you really need to take the keys off of your laptop? You may be cleaning the keyboard section, have dropped a small earring between the crevices, or simply want to brush away the croissant crumbs over the keys. Whatever your reason is, there is an easy way of removing the keys of your laptop without damaging the pieces.
Identify which keys need to be pulled out or removed. If you are cleaning your entire keyboard, then you will definitely need to remove all of the keys. It is best to draw a mock keyboard on a piece of paper and place the pulled out keys on it so that you can map them out properly when you need to put them back. You definitely do not want to misplace the keys when you take them out. Another way to make sure you put them back in the right place is to do the cleaning of your board in phases. For example, you will remove all keys that are south of the ASDF section first. When you are done, put the keys back in place and start removing those keys to the north of the ASDF section.
Prepare to remove the keys. Once you have identified the specific keys to take out, press down the key that is on the immediate left (or right) of the first key you will be removing. For example, if you need to remove the E key, press the R or the W key down. This would make the sides of the E key exposed where you can insert a pin or a ballpoint pen cap through.
Pry the key off. Use a dull tool, such as the tip of a ballpoint pen cap, a nail file, or a popsicle stick, as leverage to lift the key from the keyboard. In some laptops, doing this may cause the key to fly off so be prepared for that situation.
Take note that in newer laptop models, this technique will not work since the laptop’s casing covers the entire keyboard – there is no space for you to insert your prying tool. If that is the case, then you will have no choice but to bring the laptop to a service center.
Take extra care. Make sure the tool that you will use to pry off the keys is dull since any sharp object can damage the underlying parts of the laptop. Keep all of the removed keys in one container so that you will not lose them. To reattach the key, place it over its designated spot and gently but firmly press down on the key to snap it in place.
Remember to do this task in a well-lit room so that you can see if there are underlying wires or chips that you might hit as you remove each key. This is also a good time to check the condition of each key – there may be some pieces that need to be replaced.

How To Remove Gold from Computer Parts
Extracting gold from computer parts seems to be a trend. Old computers still have some value. It may appear as trash, but others see it as a gold mine. It can be profitable and at the same time, risky for your heath.
Prepare your materials and protective gear. You will need at least 3 glass beakers, 1 glass rod, nitric acid, glass cover, filter, steel tweezers, distilled water and sodium bicarbonate. Wear a mask, a lab coat, protective eye wear and gloves that are meant to protect you from acids and chemicals. Of course, have your computer parts ready with you.
Look for a safe location to do the procedure. A chemical lab is the best place to do this since the equipment you need may be readily available. The table in most labs is made of ceramic tiles, which is safe. Water sinks and shower heads are also within the area should you have an accident and need to immediately wash off chemicals from your skin or eyes.
Place the computer parts in the glass beaker and pour in the chemical solution. Once you extract the computer parts, clean it with any dry wash cloth to remove all the dust. You may also use a brush to reach through the pines and small parts. The beaker should be at least 3 inches taller than the computer part when placed inside. Slowly pour in the nitric acid until the computer part is completely submerged. Use the glass rod to guide the nitric acid into the glass beaker to avoid any spatters.
Cover the glass beaker and observe it for a few days. Immediately cover the glass beaker with a glass cover. Make sure it is secure and away from children’s reach. Label the beaker properly to make sure no one else touches it and place it where it cannot be easily toppled over. You may add more nitric acid in the next few days to speed up the process. The liquid should turn slightly blue.
Pour the liquid into another glass beaker over a filter. The metal parts will dissolve with the acid and eventually all that should remain are the tiny gold parts. In another glass beaker, place the filter on top and pour in the liquid from the first beaker. The filter should catch the gold. Use your steel tweezers to transfer the gold into the third glass beaker.
Rinse the remaining gold in distilled water with sodium bicarbonate. The third glass beaker should have distilled water with the sodium bicarbonate mixed into it. Keep adding sodium bicarbonate into the distilled water until it can no longer be dissolved. When this is ready, you can start putting in the gold parts to rinse it. This will remove all the remaining acids. Let it stay in the mixture for at least 30 minutes and discard the liquid mixture in the proper place. Place the gold on a white cloth and let it dry.
Now that you have the gold, the next you need is to find a buyer or to mold it any way you want. If you have enough computer parts that have gold, this should be a worthwhile endeavor. However, know that it can be risky and may affect your health. Too much exposure to chemicals can increase your toxicity and lead level in your body.
