Top 5 Things to Consider Before Buying a Laptop
You may be thinking of buying a laptop for your friends, family, or even yourself. But, you cannot just walk into a store and buy a laptop without knowing its advantages and disadvantages. Buying a laptop should be like buying any other electronics. You should give the utmost care and must have enough knowledge before buying or while buying. You can ask opinions from the salesperson but never rely on them as they want the item to be sold. So, if you are planning to buy s brand new laptop, there are certain things and tips you have to keep in mind, and they are as follows.
Budget
You cannot just go into any store and ask for a laptop that is over your budget limit. If you have a decent budget, you may go for it. If not, you should stay put and go for a reliable and reasonable one. If you are a student, you must look at your parent’s budget and if possible, contribute your pocket money as well for the laptop. If you are not a person who gets pocket money, it is better you go along with parents. There are many ranges of laptops available in the market. So, before stepping out, you must have a budget in your hand.
Processor
There is a different use for a laptop. For a student, it may be different, and for a business person, it varies. According to work done on the laptop, you must purchase the laptop that has a good processor. In short, the CPU should contain enough capacity and memory to hold huge data if you are a business person, so, you must select a laptop that has a good capacity. The most famous ones are Intel or AMD CPU brand. If this is not met, there is a high chance that your work and your laptop will end up lagging.
Hard Disk Drive
Just like the processor, you must keep a close watch on the Hard Disk Drive. This is a secured place where you keep your all data and other information safe and secured. This is also a place where you store your videos and photos a decent laptop contains Hard Disk Drive that has around 320 GB of space. But, if you are a person who saves many items and files on the laptop, you may go for Hard Disk Drive that has around 500GB space.
Screen size
The next criteria you must keep in mind is nothing but the screen size of the laptop. You may have preferences for your screens, and this can vary. If you are using the laptop for games or movies, you may need a reasonable size. But if you are looking for a screen that can occupy music and just surfing, you may go for a small screen.
Graphic Processor
The next point you must consider is the Graphic Processor. If you like watching games or even Netflix or any other movie watching, you must have a good eye on the Graphic Processor. If you want a good HD and Full HD, you must choose the right Graphic Processor.

How to Replace a Type K02 Keyboard Key
This guide is for models using hinge type K02. This hinge type is used in the following models:
Acer Aspire 3680, 5100
Acer TravelMate 2400, 4220
Compaq Presario C300, C500, V2000
HP Pavilion DV1000, DV4000, DV5000, ZE2000
and more!
Some colors in the pictures may differ for your model. That is fine, what matters most is the shape of the hinge piece.
Step 1: Orient the hinge
The plastic hinge mechanism must be oriented as shown for it to fit onto the metal keyboard hooks.
Step 2: Hook the hinge onto the base
Hook the bottom edge of the hinge over the bottom two metal hooks on the base of the keyboard.
Step 3: Secure the hinge into place
Snap the top of the hinge into place, one side at a time. This may take a bit of pressure. In this example, the top right side is being secured first. The top right and left sides of the plastic hinge should be clipped between the two metal notches protruding from the base of the keyboard on each side. You can now check that the hinge works by flexing it up and down; it should pivot easily at its axis.
Step 4: Place the rubber spring piece
If your keyboard is missing the rubber spring piece, place it in the center of the hinge. It will be held in place by the surrounding key and hinge.
Step 5: Press the key into place
Align the key on top of its place on the keyboard, and press down evenly. All four corners of the key should click into place.
A Guide to Mini-PCI Laptop Wireless Cards
A comparison of the three current standards for laptops and notebooks
This is just a brief overview of the differences between the three major types of internal wireless (WLAN) adapters found in modern laptops. We won’t get into details like different chipsets or connection speeds, just the physical differences in form factor.
The Short:
The oldest wireless capable laptops use Mini-PCI (Type IIIa), while laptops released after about 2005 use PCI Express Mini, also known as Mini-PCI Express or Mini-PCI-e. The newest laptops use the PCI Express Micro or sometimes called Half-Height PCI Express Mini.
How Old is Old?
Mini-PCI can be found on pretty much all laptops with built-in wireless networking made before 2005. Many computers that are now too outdated to have included built-in wireless at the time of purchase may still have a Mini-PCI slot, but this was used for 56K modem cards. Laptops produced after 2005 start to begin using PCI Express Mini. Today in 2012, arguably all new laptops make use of PCI Express Micro.
Show Me the Difference
It’s no surprise that the older cards are larger than the new ones. Below is an older Mini-PCI wireless adapter. It has 124 pin edge connection and an overall square shape. These cards are capable of 802.11g and 802.11b wireless LAN connection speeds.
Next we have pictured a newer PCI Express Mini card. It has a 54 pin edge connection and a rectangular shape. These cards support 802.11a/b/g/n wireless LAN connections.
And finally the PCI Express Micro (Half Height) which has a 52 pin edge connection and is roughly half the size of the PCI Express Mini card. These cards support 802.11a/b/g/n wireless LAN connections as well.
How Do I Know For Sure Which One I Need?
For starters, we’ve identified the correct type of card for thousands of laptop models within our database, so the easiest way is to browse parts for your laptop model by clicking your brand at the left. If we don’t have your model listed, you can look around the web for the answer, or do a visual check in your laptop.
Where Do I Install or Replace the Card?
We recommend first visually checking where your card is located, for several reasons. Most laptops have the card easily accessible from under a cover panel on the base of the laptop. However, there are a few models that require removing the keyboard or some disassembly to get at the card. Second, you should verify that wireless antenna cables are hooked up to your existing card, or are dangling near where the card belongs. Some older models were purchased without wireless networking capabilities would need new antenna cables to be retrofitted inside the computer.
