Help Please

My HP48GX is really going wacko. It operates so slow, I could compare it to a pentium 66 running windows XP. Is it possible that it has static electricity stored? I took an airplane ride back home and since then it takes forever to do anything. But it's working. It never seems to want to finish the selftest, so I can't same if it passes it.
Anyone out there could tell me what to do?

First save your data on PC.
Memory clear with ON/A/F.
Same problem with speed?

Yep tried all that. Even the reset under the rubber foot.
Just as slow. Yesterday it was giving a problem with the number 2. It would take forever to register the 2. I left the batteries out for about 5 hours and the 2 doesn't give any problems again. But now it's really slow.

Hi;

Try this:

switch the calculator to ON;
press and hold [ON] key;
press and hold [D] key;
release [ON];
release [D];

The calcualtor enters in interacticve test mode. Now press [MTH] key; you'll see:[pre]
ESD 210V 210V
|| ||[pre]ESD stands for ElectroStatic Discharge. See if there's any warning message and try the calculator again.

To get rid off the test screeen, do it:;
press and hold [ON] key;
press and hold [C] key;
release [ON];
release [C];

To be honest, I am not sure if this is a test for ESD or an internal ESD procedure. Well, let's see what's gonna happen!

Success.

Luiz,
You're the best. It started to beep for 5-10 seconds and now it works like a charm. Thanks a million. This forum is tops.

Hi, Randy;

thank you for your support.

The (brief) article is already there. I'd like to hear from you, guys, if there is anything else to add or anything to change/correct.

Best regards from Brazil.
