Make A Better Product PERIOD!
I've been in IT for 20 yrs, and deployed hardware from Dell, HP, and Lenovo.
The Lenovo products are in my personal opinion the worst. Their L series laptops don't even have a "drive activity light" which IMO is insane. I can't count the number of times I've troubleshot a laptop or PC acting up, by using a drive activity light to ascertain what is going on with the system. Another example is with the HP 6xx series laptops you could push ONE button on the underside and instantly have access to the insides of the laptop. With Lenovo laptops you have to remove multiple screws and then literally PRY the chassis apart, you feel like you're breaking into the damn things instead of servicing them.
Bottom line is this, make a superior product to your competition and the sales will come naturally. If you try to build the cheapest of cheap laptops, well no one will want to buy them. End of story.
