Well I am stuck with a mechanical hard drive in my HP probook 440 g3 DDR4 variant and I wish to add a SSD to extract a little more time out of this old machine. I came to know that this model laptop has a m.2 sata 3 port. I want to keep the mech drive and add a m.2 sata drive to enhance speed without reducing storage space. However I am not sure which brand or type of SSD will be compatible with this device. If anyone can identify any such SSD which is readily available. I am looking to buy hikvision E100N SSD.can anyone tell me if it is compatible?? Plus can anybody tell me how to reset bios password as I forgot mine. CMOS battery removal doesn't work.
