RE: XPS 15 9550 - TPM has "disappeared"

I also talked to a Dell technician about this problem. He suggested something much more easier:

Instead of removing RAM, Battery, ... you can easily reset BIOS by removing the power plug, pressing CTRL + ESC and insert the power plug (now the laptop should start automatically). With this combination, a BIOS reset is done. Afterwards my TPM module was visible (again). Hope this helps (and I hope I remember the key combinations correctly, but this should be the case).

In this post, we shall outline how to go about choosing the best heat gun, and also review five of the best heat guns out there
