200LX problem: Insert batteries and get a continuous beep... ideas ? Message #1 Posted by gene wright on 17 June 2013, 12:15 p.m. It worked yesterday. :-) Would not turn on this morning. Put in new batteries and hear a fairly loud continuous beep. Saw one flash of something on the screen, but it is not responsive. Took the batteries out for > 10 min. Put them back, same response. Ideas?

The solution was to pull both the main batteries and the backup one then short the contacts out (main and backup). This will, of course, erase everything so I hope you have a backup!

This did not seem to work. Here's what I did. I took out all the batteries overnight. I put in the backup battery upside down to "short" it. I then used alligator clips to connect both springs of the AA battery compartment together. Then I put the batteries back in. BEEP.... continuous. What did I do wrong? :-)

Message #5 Posted by Katie Wasserman on 18 June 2013, 11:53 a.m., in response to message #4 by gene wright Nothing wrong with that, it sounds like your 200LX has a more permanent problem. Normally a beep indicates a problem with the power supply to the calculator (typically a low battery), it's possible that some part component in the power supply section on the PCB is bad. You might try using an external power supply to see if you get the same result. Make sure you've got the right one to plug into it -- it's 12V negative center.

RIP HP 200LX Message #6 Posted by gene wright on 19 June 2013, 2:07 p.m., in response to message #5 by Katie Wasserman I hooked up the 200LX that was working fine 3 days ago to an external power supply. Same result. As soon as power is supplied, it fairly loud continuous tone is produced. Very sad. When it first did this on Monday, I am sure I saw text on the top row or two of the screen, but nothing since.

RIP? Signs of life, then death again Message #7 Posted by gene wright on 28 June 2013, 12:15 p.m., in response to message #6 by gene wright Ok, so just to play, I put the batteries back in the unit after a week. To my surprise, no tone. It began booting. The screen showed it was installing PC card drivers, then it loaded the Laplink stuff... and hung. Became unresponsive. I did not press ALT during boot, but it said it was initializing the ram disk. Any hope here with this info?
