Im using hp probook 4530s for more than a week now. its core i3 processor is as fast as my old core i5 laptop . it has an intel 3000hd graphics which is able to play games easily in low settings. it does not heat and my notebooks temp remains in 35-40 max . its a lap friendly laptop. the keyboard is great to type on. built quality is very good. the speakers are pretty loud . battery timings are 5 hours + on power saver and 3-4 hours on high performance with full brightness. the only draw back is that it has a b2 sandybridge hm65 chipset which is affected. other than that no problems.
