Here I will try to speed up two computers: my desktop computer and my Dell laptop computer. First of all I will upgrade the memory on my laptop computer. There is no point in upgrading your hard drive if there is not enough memory as the computer will not run faster. On the other hand, if we upgrade the memory and do not touch the hard drive the computer should run faster.
I have here a memory module that is 1GB and the laptop also has 1GB in it, so all together there will be 2GB, which is enough to run Windows 7.
I need to unscrew the screws that hold the plastic cover underneath the laptop.
As you can see here there are some mini PCI Express card slots, a processor heat-sink, and two memory (RAM) slots.
Here I actually have a slightly different memory module from that in the laptop. The amount of memory is the same but the memory speed is different.
I would not recommend using different modules in a computer, but at the moment I do not have a spare module that is the same. These modules are DDR2 type. How to tell which type of memory you have is described here.
The basic procedure of memory replacement on a laptop consists of two steps. The first step is to remove the old modules if there are some that need to be replaced, and the second step is to fit the new modules in the slots. In case your laptop has two modules of 512MB each then you can upgrade it with two modules of 1GB each. Make sure that those memory modules are identical. Sometimes a laptop will not power on with different memory modules. Do not worry - take one module out and the laptop should power on.
Memory slots have two latches that we need to push to the sides before removing the memory module.
To fit in memory module we do not need to touch the latches. All we need to do is to push the module in the slot and push it from the top until it clicks in the position.
Now I will show you how to upgrade your laptop hard drive to make it faster. It is very straightforward procedure. I have here a 2.5-inch SSD (solid state drive) that can fit in either a laptop or a desktop computer. It is made by SanDisk and is 128GB, which is enough for Windows 7 and my work.
I will take out the hard drive that is in my Dell Inspiron 1525 and fit this drive. With a Philips screwdriver I will unscrew a couple of screws that hold the drive in place.
Now we will remove the silver caddy (the silver part). Laptop hard drives often come with some sort of caddy. I personally do not like laptop hard drive enclosures because it makes the drive warmer.
Now we will put everything together. The laptop should recognize it without any problems.
Next we will upgrade my HP desktop computer. On a desktop computer we can upgrade the memory and hard drive to make it faster.
Memory modules on a desktop computer are slightly different than those on laptops. To access the memory we need to remove the side cover. Usually memory modules are located on the top side of the computer.
If there is one module we need to take it out and write down what amount of memory it has and what speed it is. Often it is hard to find exactly the same memory module, so a better way is to buy two memory modules or one module but with twice the memory.
We can’t just pull the memory module from the slot because there are two latches. Push them to the sides and the module will pop out.
Check what amount of memory it is and upgrade to twice the amount.
Here is how to upgrade the hard drive on a desktop computer. I will use here the same SSD that I used to upgrade my laptop.
Disconnect the cables from the old hard drive inside the computer, and unscrew screws that are on the side. Sometimes screws are hidden behind a metal panel, so you need to find out how to get there. Connect the two cables to our SSD drive and place the drive inside the computer. Usually desktop computers do not have a fitting place for 2.5 drives so I am leaving it like this, or you can buy a bracket that will allow it to fit into a 3.5 drive place.
The results. With those upgrades my desktop computer is lightning fast. It has very short startup time and the shut down time is 4-5 seconds.
The laptop on the other hand did not take this particular SSD for some reason. No matter what I changed in the BIOS it refused to see the drive. I think I need to use a Samsung SSD.
