CNET's Forum on laptops is the best source for finding help, troubleshooting, and getting buying advice from a community of experts. Discussion topics include hardware component and upgrades, ultrabooks, gaming laptops, Netbooks, and laptops accessories and much more.
Some may not like my stance against no name laptops with hard to find, nonexistent service centers, or lack of spare parts. HP, IBM (can't write about the new owner), Motorola (not a laptop maker but I know about their service) Dell and others have plans to keep parts around for the lifespan of the laptop. While some may find it short at 3 years, that's the last number I found for such company plans for spare parts.
Given the high failure rate of about 1 in 4 notebooks over the average lifespan, it pays to either go with the names. Or consider tossing it out after a few years when it fails.
