I'm using this lenovo G500 laptop since 3 years. It's Really Very good. It Comes with 500 gb rom and 2Gb Ram. Ram compare to nowadays laptops to much less but it's really giving good running system.
Battery backup still good after 3 years. Still 3 to 4 hours back up.
It comes with another good features like Dolby Advance audio. That increase sound quality.
Keyboard also good.
It comes with another great feature One key Rescue system.
Overall in last 3 years it gives me good work and still.
You can buy this one
