TI-92: Power loss while not in use.

Anyone had a problem with the 92 losing power over short periods of time? I think it might be a bad capacitor or something.

Hello,
You may be right. I have left batteries in my TI92 for years without using it. When I put in fresh batteries, it came back to life. The backup battery of my TI92 (bought a dozain years ago) has not been changed yet.

Hope it helps.

Check the timing chain. Some times the chain will shift with worn teeth and get out of synch. This will cause the engine to lose power and back fire. Sometimes with a flame through the carb. I did that one once. Easy fix if it is the problem.

Hello, after installing processor, memory module and grahics card, the MB AOpen AK77-333 makes a couple of CPU fan revolutions after it is powered-on and then stops. Thank you for the reply,


That old puppy may have bad Electrolytic Capacitors.

(Radial Aluminum Electrolytic Capacitor)

Specifically the ones in the motherboard voltage regulator circuit, and more specific the ones used for the voltage regulation to the Processor.

Visual signs of capacitor failure,

http://www.capacitorlab.com/visible-failures/


{ Back in the day there was espionage at a large capacitor company.
An employee tried to abscond with an Electrolytic Capacitor paste formula.
The company got a heads up before this transpired, and she was given a bogus formula.

The formula didn't have the correct chemical composition, and would develop gas after a time period.
The gas (Hydrogen Gas) expands in the capacitor, and causes seals to be compromised, where the paste is then pushed out.
So much paste loss, and the capacitor can operate in a weakened state.
Too much paste loss, and the capacitor fails

The AOpen motherboards were made in this time period, and not to slam AOpen, but they grabbed up on cheap quality capacitors. Guess which ones they got? AOpen is now out of business.

There were 1000's upon 1000's of these Electrolytic Capacitors made, and they are STILL plaguing electronic components today.

Just a heads up if you find problems with other electronic devices, or components also.
(I replaced some in a Modem. Modem has worked great for 2 years now)

Problem is that Electrolytic Capacitors do not always show visual signs of failure. The paste can also dry up inside, and no outward visual sign will be apparent.

It could also be a bad Power Supply with a weak voltage power rail.
Enough power to light LED lights, and maybe spin fans a few times, but not enough power to turn the Processor on.

1) ALL of the LED light on at once use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts of power.

3) A typical Processor can use 51 to 125 watts of power.
Depends on what processor it is.

AOpen AK77-333?

Socket A (Also known as Socket 462) processor socket. Uses AMD processors with up to a 266MegaHertz Front Side Bus. (266MHz FSB)

AMD Athlon , or Athlon XP, or Duron.

I think you have a bad capacitor in the power supply circuit. You need to have a certified technician look at it though. Get someone who is familiar with mitsu's though. Have a great day. Jay

I have a Nikota 3500 generator, and I had a shorted circuit in my cabin. Now the generator puts out only 92 to 103 volts. Is there something I can do to fix this myself? Do you think it may have knocked...


Hi,
Usually a power surge (short) or sometimes an overload will take out the diodes. Like you have suggested I would say that you have just knocked out one... Test them and replace the bad one and you should be good to go.

I hope that this will help you to solve your problem!

Thanks for using Fixya!!
