Since begnning computers in Nov 1998 I have had 4 desktops and 3 Laptops. My current laptop is a Dell Inspiron 5040 with windos 7 Home Premium SP-1. I also have a Windows XP laptop. My wife has a Windows 10 laptop and we no longer use the older Windows 98 desktops but are afraid to dispose of them for fear of what personal info might be retrievable. I used to do cleaning operations on the desktops like clean hard drive etc but with the laptops for some reason have not. Mybe the mdern computers do no not need it or maybe i just did not think of it. I was wondering if there is still a series of cleanings that could or should be done regularly with laptops. and what they might be and how to do them. Just thuught I would ask. Any tips or advice? Thanks.
