NEVER leave your laptop or any valuables in plain sight in your car. Recently there has been an increase in car burglaries stemming from valuables being left in plain sight. Lock them in the trunk.
How will you use the laptop? One of the problems when you buy a laptop is that you pay for features you don’t really need. One of the best ways to avoid paying too much is to consider how you will use the laptop. If it is mostly for word processing, then settle for a cheaper machine. If it is for gaming, then you need a more powerful one.
Capacity-wise, they’re relatively small – usually well under 100 MB. However, they’re very useful for moving files quickly and easily from one computer to another, e.g., moving a PowerPoint presentation from your naprawa laptop?w to your business associate’s laptop.
The final factor would be pricing. This is completely a personal choice but you do get what you pay for. Laptop prices have dropped dramatically these days and a laptop can be bought for as little as $1000. Considering a couple of years back you couldn’t get a laptop for under $2000 this price isn’t too bad. But of course it all comes back to your needs. If a high end laptop is what you need for picture or video editing then expect to be paying over $2500.
Laptop batteries generally don’t maintain a full charge for more than a year or two at most. The manufacture date of the laptop is often found on its underside. If the manufacture date is more than two years and it has an original battery, consider yourself lucky with any battery life you get. Most used computer dealers will not give you any warranty for the battery. An extra battery is always a wise purchase when buying a used laptop. Consider asking the dealer what it would cost to get another one.
DDR2 is an evolution to DDR with some internal enhancements to boost performance and usually available in capacities up to 2GB (per module) and speeds up to 1066MHz (effective).
A mobile cart to house the laptops is often the most over looked item for your mobile labs. Your cart will need a power strip to charge the laptops. Your cart will need some sort of lock to prevent theft. It also needs to be easily moved from class to class. If the cart is too large and bulky teachers will hesitate to use it. Next, your cart must be user friendly so students can take out the laptops and place them back in easily. I have seen schools make there own laptop carts and you can purchase them from various vendors. Just remember if the cart isn’t easy to use then your laptops won’t be safe, teachers won’t use them and they will get stolen or broken.
When upgrading laptop memory you need to identify what type of DDR memory is used thus supported by your laptop. Failing to do this will mean a failed upgrade for a very simple reason – all versions of DDR are incompatible with each other and use a different type of slot connector, which differs in the number of pins (and several other technical aspects).
