Question about Office Equipment & Supplies
My calculator won't turn on. I already tried the RESET button, pressing the A and F while pressing the on key. What else can I do? I'll take my SATs soon! I really need it! Thanks!
Well, before trying something like opening the calculator, I'd advise
archiving anything that you want to save to your PC. But what's done is
Are you sure that you're inserting the batteries with the proper polarity? Are you sure that the batteries are good?
It does sound to me like some sort of hardware problem, but strange things could happen if RAM gets corrupted (such as by being without power for too long).
It could be that the calculator really is on, but isn't displaying anything. The following solutions assume that the calculator is on.
Try a warmstart, that is hold down the ON key, press and release C, release ON.
If that doesn't work, try forcing a warmstart with a paper-clip reset. Remove the upper right (as viewed from the back) rubber foot. You'll see a small hole with the letter R next to it. Insert a straightened paper-clip (or something similar) straight in as far as it will go, and release it.
If that doesn't work, and you're willing to lose everything you had stored on the calculator, try clearing all user memory. Hold down ON, hold down A, press and release F, release A, release ON.

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

Hi, if pressing on and F5 together immediately starts the selftest your keyboard is OK, but one of the capacitors on the HP49G PCB are broken. I replaced all three and the turn on/off problem was gone.
Hope this helps.
