Question about HP 49g+ Calculator

My HP won't turn on anymore

I had loaded some tgv files and was using it during a test. Suddenly, while using the equation editor it jammed and then it turned off and never turned on again. When batteries are on, you can notice some activity on the LCD display, but nothing interesting. I tried resetting it and tried taking all batteries off to see if it went back to but nothing happened as well. What should I do? Thank you in advance, Bruno

    The unit was in my desk for some ime, and I guess the batteries died. I replaced both the backup and the AAA's. I removed the memory card. Reset does not work. No USB connect.

I just fixed two "failure to power on" 49g+'s. For the first one I did a moderate slap of the unit against my thigh and then tried a reset (I thought maybe the reset was jammed with some debris) - it worked! The second one just needed me to scrape off some corrosion (an old toothbrush works) from the battery terminals - AJ

Try a cold start, reseting the calculator, introducing an wire in the back small oriffice in the calculator. It may fix the problem.

My Subaru 2004 WRX is throwing ODB codes P1086 and a P1092. I hava an emmission test in CT coming up. What do I do to check / fix?

both codes refer to the LH driver side tgv.
To repair the tgv faults mentioned above requires removal of the intake system, intercooler, fuel lines and the tgv units.
I would highly recommend a professional fot this repair.
Used parts can be located at the link below.
The sensor is actually a throttle position sensor.
They are not cheap and can run $200+new.
The tgv units are an emission control device and need to be working to pass an emissions test.

So many questions about how to do specific mathematical equations using specific calculators....

I hear you. The problem is that there a lot of facts and algorithms to remember (approximately) and a human memory is limited. Why bother spend half an hour doing what a calculator can do in a fraction of a second. Personal prowess is a nice thing for show, but if one has to be efficient, a powerful HP calculator is more appropriated than a genius with the Japanese abacus.

Having message jam inside rear door and can not find any paper jam

Not all of the paper jam was actually cause by paper. There are also instances that the media is the one that is jammed, causing to display a "paper jam" message.

If you can't find any jammed paper from the unit, you can try inspect the following cause..
1. Trays are loaded improperly or overfilled.
2. Tray 2 or tray 3 is removed during print job.
3. The top cover is opened during print job.
4. The media that is being used does not meet HP specifications.
5. The media that is being used is outside of the supported size range.

Also, try to tun HP toolbox.. on the Paper Jam options, click the Typical Jam Locations... to see the internal paper path and potential jammed locations.

I hope this solve your problem...thanks..

When I turn my printer on (HP J4680) it always tries to load a paper and immediately jams (even if I cycle power an unplug). I cannot use it anymore....

If you disconnect the printer from the computer and your printer stops trying to feed paper when you turn it back on, then this solution likely won't help you.
  1. Disconnect the printer from the computer.
  2. Disconnect the power supply.
  3. Turn the printer back on.
  4. If the printer tries to load paper and jams again, your printer is trying to recover from a paper jam, so try this video. I'm betting if you follow the instructions in this video, you'll resolve a jam in the printer and solve your problem.

My wonderful HP 2575 cannot print good quality photos anymore

Had similar problem with my HP printer. Used cotton swab, soaked in rubbing alcohol, on all the rubber rollers. My printer has a removable back panel that gives better access to the rollers. May have to apply the alcohol several times to remove buildup and to help restore roller "grip".
