I'm running XP home on a Dell inspiron 8200 laptop. Because it is so slow, and because I need to access my computer multiple times per day, standby seems like a good idea. Any time I close the laptop, or if i leave the computer for an hour, it tries to go into standby, but then I get an error that says the PS/2 keyboard is preventing standby. I have looked into the issue a little bit, and read that it is not actually the keyboard, but another program (adobe reader was listed as a potential cause) was preventing standby. I believe just about all of my programs are up to date, but I'm not sure which one is causing the problem, if that is the case at all.
