got several suggestions for an update.
Yesterday I went to the pulmonologist. Got the official okey dokey to go on room air during the daytime, no more dragging an O2 tube around the house behind me!!!
That means:
I can send back the huge H tank of 24 hours emergency power blackout oxygen supply they put in the house - 5 feet tall and gawd only knows how many PSI of pure oxygen....
put it this way, the physicist in me abhors the pressure inside of the thing (2 to 3 thousand PSI) (inside of a house/ living structure)
the chemist inside of me abhors the reactivity of that much pure O2 in one place. (inside of a house/ living structure)
In a fire that would be one HELL of an explosion.
AND NOW I CAN GET IT OUT OF MY HOUSE.
as well as other things that can now also go....
so, yesterday was a milestone I had been anticipating for quite some time.
and
about two weeks ago, the NEW Dell laptop that I had been using in the Hospital(s) developed a dead Ethernet port.
After the usual servicing by remote attempts, it was determined that it needed to be sent in.
Thus my work in fixing the OLD laptop that died while I was in the hospital was quite fortuitous (dead hard drive replaced)
and I set that one up to use in the interim. ( remember I carped about "computer problems" in a few posts?)
Dell service replaced a daughter board that serviced the connectors on that corner of the laptop.
when it came back, the Ethernet port worked fine, but the USB ports on either side of it didn't.... :tears:
The Costco concierge service must have sent a lightning bolt through Dell, I had service supervisors out the wazoo on the case...
turned out the NEW daughter board's usb controller chip(s) were so new Windows did not yet have the drivers for the chips in Windows
but they did have them available for download, so after they were installed, the USB's were back up and running,
better than ever...
BETTER THAN EVER????
Yup, the old USB ports were USB 2.0, the new USB ports are now 3.0 !!!
better than ever
