Buy laptops for mobile laboratories is often a daunting task for an educator. Mobile laboratories can be a great advantage if you buy the right equipment. Mobile laboratories have shown increased test scores and help students focus. If the wrong type of equipment is purchased the lab mobile laptop will become a giant paper weight.
Laptops students should have the following qualities: Must be "Light", a computer truly portable light is less than four pounds. A laptop is 8kg heavier. The problem is that does a really light laptop over $ 2,000 to schools can not allow, so a laptop in the range of six pounds is good.
CD-ROM drive for portable computer labs at the school are optional, if not completely unnecessary. I say this because they are usually the first thing to break. Second technical team installs all the necessary software through pictures ghost or network. Third parties without your CD-RW or DVD-ROM eliminate the temptation of using laptops for non-educational use.
Then, the need laptops at least 512 MB of RAM (memory), most educational software is very graphic intensive and require lots of memory. Anything less than 512 MB memory to make the laptop to freeze from time to time causing frustration for students and teachers.
Hard drives only need 30gigs. Software installed for a school laptop should max out around 4 gigs. Students may not download music or movies so that a hard drive bigger is not necessary.
Then the real profile of the laptop should be thin. Children have smaller hands and the thickness of the laptop more uncomfortable it is for them to type.
Fourth of laptops need to have an integrated 802.11g wireless adapter. The adapter must be integrated into the laptop. If you decide to use a wireless adapter PCMICA get beaten and bruised and broken with the first month of use.
The laptops need to have a Pentium M or Centrino CPU's. This extends the battery life of 3.5 hours vs. 2 hours with the technology Centrino. The usual rule is that the batteries can be expected to replace them every year. The term replacement laptop battery can be extended for not letting that the batteries drain completely.
The portable computer monitor should be 14 "or 15". Anything smaller is too small for children to read, and something bigger is too big and bulky.
Then, the need for adapters laptops Ethernet network in case they need to connect directly to the network. Finally, Windows XP Professional must be installed for your operating system.
A mobile cart to the house of laptops often is the most searched its mobile laboratories. Your shopping need a power strip to charge laptops. Your cart need some sort of lock to prevent theft. It must also be easily moved from class to class. If the carriage of teachers is too big and bulky hesitate to use it. Then, your car must be user friendly so that students can bring laptops and the place again with ease. I have seen schools that there are cars own laptop and you can purchase from multiple vendors. Just remember, if your car is not easy to use their laptops then no be safe, the teachers do not use and receive stolen or broken.
Finally, before deciding on a line of laptops check Web sites like cnet.com and amazon.com and read the reviews. Also call your local district and find out what technology they are using for laboratories phones. A good rule of thumb when buying technology is that I will not be another test case.
