I have two M7780s. They are identical in all aspects. One now will not load Dell Command Update. The other works fine. I spent over two hours with Dell Support over the weekend following the various steps found online at Dell and also using ChatGPT to crosscheck. This same M7780 had the much discussed power adaptor won’t charge the battery problem.
The M7780 is a superb machine when it works; but it is really not acceptable that the machine is so quirky and unreliable. To get one to work properly, it took three machines; and this machine had to completely rebuilt at my office by a Dell third-party vendor. It is worth the hassle to me because the M7780 is the only laptop powerful enough to run the programs I need to run. I wound up purchasing two identical M7780s because I needed to have reasonable certainty that at least one would be working when I needed them to work. Dell still has not figured out either issue - the sudden failure of the power adaptor and the inability of Dell Command Update to load.
