You will probably want to uninstall the trial version that came with your new computer and install the 2003 version. However, unless I'm wrong the 2003 version could only be installed on one computer and when it's time to validate it you will have to contact Microsoft and explain the situation and hope they allow you to validate it on your new computer.

I am happy for you Susan! I have bought several electronic devices from woot all with great success never a problem. I wanta to get a new computer for my husband his laptop is old and slow and has issues. I have been thinking about a desktop instead of the laptop too. His eyesight is not as good as it once was I think he would enjoy a bigger screen. I am seriously considering putting a Linux operating system on it just because of the whole windows 10 debacle. The latest version of Linux mint is so much like Windows 7 and he's been using android on his tablet and phone. It would end my having to deal with keeping his computer updated, very easy on Linux. I hopeyou get lots of use from the new computer!

Final verdict on your new PC will be your cat's approval .... Is the keyboard comfortable enough to lay on? Is the screen small enough so as a cat paces back and forth in front of the screen as you try to type you are unable to see what you are doing and will stop to pet the cat?

I have 2 HP Pavilions at my house and do not have the problem you are experiencing. I did have an issue that my battery would drain to very low charge if the computer was stored for a week. However, my issue was more with the "Window10 operating system than the computer. Something was active when the computer seemed to be shut down. A fully charged battery should be able to keep the BIOS settings alive and the clock/calendar running for many days, probably months. I did find one setting that was causing a drain. About slow to not charging: Two items could be at fault. One is the power supply that is in the power cord. One cord plugs into the household electrical outlet and the other end, carrying DC power goes to the computer. The power supply may be faulty. There has been problems with batteries shorting from over charging or trying to charge a failed battery pack. If a portion of the battery pack has shorted, then its output voltage would be diminished and a charger trying to bring that pack up to voltage overcharges the remaining good cells. If it does not fully charge overnight, there is something amiss. The problem could be the battery pack or the power supply. Our HP Pavilion computers come up to near full charge in 2 to 3 hours. By the way, make sure you did not plug it into a switched outlet that goes dead when you turn the lights off.
