One drawback with HP that I found is that it does not have battery charge management tool to limit charging. The main limitations with batteries are number of charge cycles and at what charge level the battery is used. That is, if you keep charging and discharging, the battery will not last long. Also, if you keep always charged at 100%, the battery will degrade very fast. Most laptop manufacturers have tools to limit charge to, say, 80% and hold it there if you are always using the laptop powered by AC ( like a desktop ). But HP has provided this only for the business laptops not the consumer laptops ( I think this is to be able to sell batteries ). If you are going to be using on a desk for a long time and only occasionally use it on the move, this is something worth considering.

Acer is poor in terms of service. They provide services through third party it take 15 to 30 days to resolve simple issue. Moreover, third party give so much excuse to visit your house.
HP is best in terms of service quick resolutions and i feel built quality is best in hp.
Note i have used acer, dell, lenovo and hp.
For me HP is best in terms of quality of product and services.
Built quality of lenovo is not good. Strictly Avoid.
