A cheap laptop from Lenovo with entry level Intel Celeron dual core processor B1000M clocked at 1.8GHz. This is a 3rd generation processor ( Ivy Bridge) with Integrated HD graphics which is based on the HD 2500. This Lenovo G580 59362301 model comes with 2GB DDR3 RAM and 500GB of hard disc drive. The display 15.6inch HD Brightview LED type with a resolution of 1366 X 768 pixels. The best part of this cheap laptop is, it comes with the Windows 8 operating system which is an attractive feature. Unfortunately, there is no dedicated graphics and the Integrated graphics has no good enough power to drive the latest titled games which needs more execution units. Browsing, watching HD videos and editing photos and documents did not slowdown this laptop. However the 2GB of RAM on a Windows 8 operating system may slow you while multi tasking and you may upgrade the RAM to higher capacity up to 8GB without any trouble. There is only one DIM slot to insert your RAM and to upgrade with a 4GB of RAM you may have to remove the existing 2GB memory module to insert the new one to get better performance on this Lenovo G580 laptop. However considering the price of this laptop, an additional spending on a 4GB RAM is not going to take you above the Rs:25000 budget. The optical disc drive on this laptop is SuperMulti DVD RW Drive with Dual Layer Support. The display is glossy type which is reflective and the horizontal viewing angle is also not so wide. The keyboard is an another good part on this laptop which is a chiclet type with good enough spaces between keys and good responsiveness. The muti gesture supported touchpad is very responsive which is good while you navigate through the Windows 8 operating system. There are good number of output port for connectivity. There is 1 No of low speed USB 2.0 port and 2Nos of high speed USB 3.0 ports for data transfers. There is no HDMI port and have a VGA port for your external monitor connectivity.
