A cheap lightweight laptop computer is typically considered any laptop under $1000 with a weight of 4.5 lbs or less. Most new laptops on the market weigh more than 5 lbs. In general the lighter or thinner you go the more expensive the laptop. While new laptops under $500 can be found with weights just over 5 lbs, a new laptop weighing under 4.5 lbs typically goes for at least $800. Looking through several online laptop stores I found the cheapest lightweight laptop computers.
There are a few popular manufacturers that offer new lightweight laptop computers under $1000. Everex and HP both produce cheap lightweight laptops with 12.1" screen sizes and prices under $1000. Asus builds an ultralight 7 inch mini laptop that goes for as little as $299 but has a hard drive capacity of just 2 to 4 GB. You can often buy a new lightweight Toshiba or Dell laptop for under $1000 as well.
