I came accross this one today.
Here is how to fix.
1. Click ok.
2. Find the ‘TSP1-wave.dll’ file found in the ‘C:\Program Files\Wave Systems Corp\Common\NTRU12′ folder
3. Copy and then rename to ‘Tsp.dll’ and then move it to ‘C:\WINDOWS\system32′.
4. Reboot and the error should not appear anymore.
First problem report on the Dell Studio XPS Laptop 1645. The battery latch is defective. The first time I took the battery out, I could not put it back in snug. It will not latch all the way. I opened a online support chat with Dell and they are sending out a tech to replace the latch assembly. I think this might be a known issue.
