Thanks to everyone who responded!
I tried attaching an external monitor, and I could not get that to work either. There is a function key that switches the displays, but that did not work. So, there may be more wrong that I originally thought. I also could not get an Ubuntu CD to do more than exercise the CD-ROM....no visual feedback on the screen.
I checked the HP and Dell refurbished laptop sites, and there weren't any under $500. Craig's list had some boxes for $200 - $500, but I have had mixed success with computers from Craig's list.
Stephen, I really appreciate your offer. Let me return the favor and say if you need some D620 parts in the future, send me an email!
Instead of putting money into a new/used computer for 5 months of use, we decided to get the MacBook Pro ahead of graduation. <father bragging> Since she is ranked second in her class, I am pretty sure she will graduate...;) </father bragging> I had a friend get it for me with an Apple employee discount, so it was not as painful as it could have been. I am going to pull the hard drive from the D620 and put it in a usb caddy and hope I can recover her work from last semester. Wait for the screams of excitement and joy from my daughter on Christmas Day.
All the best to everyone on and off the list....Merry Christmas, Happy Kwanza, Happy Hanukka, Happy Holidays!!!!
