Why do you call this "politically correct"? It's an issue of mixing
religion and science. The new terms were chosen to separate a single
religion from having defined notation for a scientific purpose. How is that
a matter of "political correctness"?
 
I have found the only time this term is used is when someone wants to
criticize something as being "politically correct" as if that automatically
makes it undesirable without actually discussing the facts.

Nothing annoyed Christ more than feeling like he wasn't being given

Apple iOS 11.2.5 Release: It's A Big One
<https://www.forbes.com/sites/gordonkelly/2018/01/01/apple-ios-11-2-5-release-iphone-battery-problem-slow-down/#52fb94c53b5c>
 
Verbatim quotes:
"We expect the iPhone X to be throttled in late 2018 with replacement
batteries for it back to full price by January 2019."
 
"Samsung guarantees 95% battery capacity retention for the first
two years of ownership. Meanwhile LG and Google offer two year
warranties, which also cover the battery."
 
"Apple's promise of a limited time price reduction (11 months) on new
iPhone batteries doesn't cut it, particularly with the swap taking
three days and no further pledge from Apple to change anything
going forward."
 
"Apple has admitted it slows iPhones - and coincidentally just after
the release of each new generation - to protect their already degrading
batteries from shutting off if the phone were to continue operating at
full performance."
 
"Not only does the well promoted title of Performance Champ suddenly
ring hollow now we know this *only lasts for one year*, but we also
know this behaviour isn't normal. HTC, Motorola, LG and Samsung are
among the major brands quick to stress they see no reason to throttle
the performance of their smartphones."

"exprect" is the keyword here. Speculation by some snews media. This is
not a statement from Apple and thus useless.
 
The product development of the X was done with knowl;edge of the
batterty problems for the 6s. So it is possible that it was fixed or
significantly reduced.

I think that's wishful thinking (sans facts) for two big reasons:
1. What you hope goes diametrically against what Apple actually said.
2. Apple didn't change their power-hungry single-threaded architecture.
 
Backing up those two facts is this recent article:
Apple Won't Stop Throttling iPhone Performance
<https://www.extremetech.com/mobile/261243-apple-cuts-battery-replacement-costs-wont-stop-throttling-iphone-performance>
 
That article clearly says Apple "won't stop" throttling of *all* newer
iPhones after about one year to about half their original CPU speeds.
 
Hence, the article makes the same claim that I do which is that Apple
iPhones effectively cost a *lot* more than just the sticker price:
 
"The effective cost of buying an Apple device is significantly higher
than it used to be, at least for people who keep their hardware more
than a year"
 
And, the article reiterates that Apple outright lied to its customers:
 
"Apple acknowledges that it failed to properly inform users about the
changes made in iOS 10.2.1 and the introduction of this throttling."
 
Interesting fact, since the Apple Apologists still deny what Apple already
admitted. Another fact that the Apple Apologists will hate is that this is
an Apple-only problem.
 
"Apple tries to dodge responsibility for its own smartphone designs"
"This is an Apple-only issue."
 
Everyone (but the Apple Apologists) already knew that this problem is an
Apple-created Apple-design problem, where *all* the major Android
manufacturers have gone on record publicy asserting
 
"Android phones do not perform this kind of throttling".
 
What's more interesting than that is where this article goes into decent
detail on the one thing that's different about Apple design:

"Single-threaded performance is the one area where Apple clearly
stands alone."
 
Interesting. The article posits that the Apple single-threaded design might
be the main reason why Apple batteries can't handle their phones:
 
"there's a strong relationship between power consumption and
architecture"
 
In summary, it's purely wishful thinking that Apple won't throttle *all*
their latest iPhones after one year because:
1. Apple themselves clearly said they'd throttle all their newest iPhones.
2. Apple didn't change their power-hungry single-threaded architecture.
 
Remember, this is an Apple-caused Apple-designed Apple-only problem,
despite nospam's clever hands-caught-in-the-cookie jar Apple Apologists'
attempt at saying Android manufacturers also *secretly*, *permanently*, and
*drastically* throttle CPU speeds of their phones after only one year of
ownership.
 
Everthing I state is a fact.

Yep. I stick with Eneloop. They might only quote 75% of the power of some
brands but it's real capacity and is useful for hundreds of cycles.
 
I love my Maha MH-C9000 WizardOne charger. It cost me quite a bit back in

Anyone know if there is a solution to low display brightness on a HP 54111D oscilloscope, like maybe power supply capacitor replacement?
 
The CRT power supply voltage described in the service manual is puzzlingly-low...only 120 VDC (?!?) The 300V switching supply is described as used for generating the 5V logic supply.
 
I haven't dug further, but wonder how a color CRT can get by with such a low voltage...or if the CRT module has an integral flyback supply for anode voltage, and repair being module-focused, isn't discussed.
 
The CRT thought led me to wondering if CRT rejuvenation was an option.
 
Thanks

Hi Murray,
 
Do you have the CLIP for the 54111D available? Can you get hold of an ESR
tester? And where abouts are you located - 120 or 240 volt land?
 
You might go on the HP Yahoo group with the same request.
 
https://groups.yahoo.com/neo/groups/hp_agilent_equipment/info
 
It does sound like one of the bulk capacitors has failed if the 300 volts is
that low.
 
You must get the power supply working first before any other diagnostics are
done.

Never do that. I've seen so many CRTs ruined by rejuving. Increasing heater voltage works better and stays good.
 
But if your PSU rail is way out of spec, surely it's obvious that CRT emission failure is not likely to be the cause of a dim screen.
