Hey guys, The HP 4540s notebook comes with Intel i5 processor 3rd generation, 4GB of DDR3 RAM, 500 GB harddisk, integrated intel graphics of 2GB, 46 Wh 6 celled battery, fingerprint reader, 15.6 inches led display of 1280x720 resolution display. The performance of the laptop is ok it still comes with the clock speed of 2.5Ghz and cab be turbo boosted ul 3.1 Ghz but it runs under the 3rd generation processor which is not at all worth now, but the performance is ok while we come to any lags, there will be no lags but high definition games cant be played because it has only 4GB of RAM with a speed of 1333 Mhz which is very low and it have the old version of RAM that is DDR3. The look appearance is a little bit fat compared to the latest laptops, the speakers quality is good, we can do multitasking, but heavy applications cannot be runned at the same time then there will be a lag in the performance, in simple words now we cannot buy this laptop it is not worth it though it may have nice features.
