This power lead is compatible with the PCG-GRS laptop. It is ONLY for the power cable, and is not the power adaptor which is the big black box that this cable connects to. If your laptop requires the box then please search for the adaptor. Please also note that manufacturers tend to make different types of adaptors and in this case this cable is for Sony Vaio adaptors which use the Clover Lead cable to recognise this type of adaptor, check to see if the adaptor has a mickey mouse or clover figure where the power cable connects to it. If it does not then you will require an 8 fig or kettle lead.
