I have a R52 type 1859 laptop. Its been working great until today. I noticed that while the laptop was turned off completely, the numlock, capslock, and hard drive indicators remain on. Also, while its off, if I unplug the AC power cable from the machine, they turn off. When I start up and log on, they continue to stay on constantly. Normally, the hard drive light would flicker accordingly with the drive activity but once the laptop loads up, its shuts off.
While using the machine, these 3 lights never shut off and they are constantly lit (no flickering)
Also if I press the capslock or shift-numlock keys, the lights never turn off or on BUT the function works - meaning that the letter go all caps and the num lock numbers keys engage.
Finally, I also noticed that the display flickered today between dim and bright while plugged in. It stayed dim for a while but now its back to bright mode.
Any ideas what might be causing this?
