Hewlett Packard no longer has its HQ in Palo Alto. The old Hewlett Packard company split into two in 2015. One of the new companies is HP Inc. (which is not entitled to use the Hewlett Packard name) and is still in Palo Alto. The other new company, which retained the name, is Hewlett Packard Enterprise, and that one has moved its HQ to Houston.
This still hasn't been updated. HP is no longer the same as Hewlett Packard, they are two separate companies. HP Inc is in Palo Alto but Hewlett Packard Enterprise is in Houston. There is no longer a company called just "Hewlett Packard".
You would have Ü on your keyboard and never use U in its place as it so often changes the meaning of a word completely.
