Some HP-50G Questions

[edryer]

Quote:For what it's worth, I've only ever seen one HP 50g unit with a faulty LCD (in photos, not in real life) and read about one with bad solder joints.

Yes. My (very limited experience, have only two units!) conclusion is that the HP-50G is actually so far a very reliable device and I have also only seen the same posts as you probably.

Amazon (US) rate it 4.4 with 864 reviews (90% 4 or 5 star) with the low star reviews often given it due to it being "overly complex" (!!!!) - only one or two on QC issues.

The TI-89 Titanium rating 4.2 - ‎1,049 reviews - itself a very reliable device, scores slightly lower.

My experience of Amazon is that if an electronic product has any even minor QC issue there will be a sufficient number of 1 star "angry" ratings immediately noticeable.

Another interesting issue:

I always had a Samsung Micro SD Card (2GB) with a holder in the HP-50G, and when powering on there was always a three second or so delay before the LCD came alive and the Calculator functional. I thought this was normal...

I then managed to buy a 2GB "pure" SDHC card and used it in the slot - imagine my surprise when the Calculator started instantly!

It seems when using (at least in my case) Micro SD Cards + Adapter in the 50G there is a long delay to startup not seen with a straight SDHC card.

Both cards were formatted and "empty" to test.
