MidnightCommando Posted May 6, 2011 Report Share Posted May 6, 2011 Hey guys! My OMP/H1000 is dead in the water - it /was/ working for quite a while until its batteries died (I used high-performance alkalines) and I simply left them in there for a week or two until I got replacements (I ended up purchasing Varta NiMHs because I can recharge them and they're known good) ... So I put in the battery holder, with its new batteries, and it's simply refusing to turn on. I know the batteries are good, as is the backup cell. I took the MP partly apart to see if I could spot any glaring problems, but the board looks in perfect condition as far as my untrained eyes can tell. Can anyone offer some suggestions? I don't have any contact cleaner to spray all over it, but I should probably get some in the interest of keeping this Newton alive as long as possible - so for the meantime, simple stuff that I might have overlooked that may just fix it?

beachycove Posted May 7, 2011 Report Share Posted May 7, 2011 Does it have a reset button like the later models? I have had this happen with a MP2k, the solution being a soft reset. You may need a manual, because wrong use of reset button on the 2k models will wipe the system (via a hard reset, meaning that it is restored back to factory defaults).

MidnightCommando Posted May 8, 2011 Author Report Share Posted May 8, 2011 I've attempted both a Soft Reset and a Power Reset as per http://support.apple.com/kb/TA33869?viewlocale=en_US - to no avail. Nothing showed up on the screen at all, and no sound was made. Quote Link to post Share on other sites
macgreg Posted May 8, 2011 Report Share Posted May 8, 2011 Bugger - is this the one I sent you? Have you tried the methods described here:http://www.pda-soft.de/faq.html? Let me know how you get on... Quote Link to post Share on other sites
MidnightCommando Posted May 8, 2011 Author Report Share Posted May 8, 2011 I did follow those procedures. Unfortunately 'twas all to no avail. It is indeed the OMP you sent me, macgreg I'm hoping to revive it at any rate because while I have some eMates to test things with too now, I did have data on there, and I was actually using it as a PDA until it ran out of batteries Quote Link to post Share on other sites
jsarchibald Posted May 8, 2011 Report Share Posted May 8, 2011 Heard a similar thing on the retromaccast podcast, there were 4 options available. I think they removed the batteries, as well as the watch type battery, left it overnight and it worked fine. Good luck! Quote Link to post Share on other sites
Byrd Posted May 8, 2011 Report Share Posted May 8, 2011 Hi mc, I picked up a similarly dead H1000, and did get it to fire up by taking it apart, cleaning all the contacts with cleaning spray/solvent, "exercising" the power switch, and it fired up fine without issue. Problem is, you leave it powered off ... and it won't start up again without similar coaxing (remove all batteries, exercise power switch), very stubborn. Once it finally powers up, it'll come up with an error about a problem with the power or something at startup. JB Quote Link to post Share on other sites
MidnightCommando Posted May 10, 2011 Author Report Share Posted May 10, 2011 Well guys, I feel like a complete and utter moron now. It just occurred to me to take a voltmeter reading across the battery cage. It read +0.78V ... not really enough to boot a Newton, hrm? Investigating further, I checked the voltage across two of the NiMH cells. Those same cells I was /certain/ were charged. Just under 0.1V. That struck me as very odd - again, no wonder the MessagePad won't boot! I'm now recharging the AAA cells, hopefully that will fix my problem. I'll report back sheepishly when done.

macgreg Posted May 11, 2011 Report Share Posted May 11, 2011 Good news! Hopefully this sorts your OMP out! Quote Link to post Share on other sites
MidnightCommando Posted May 11, 2011 Author Report Share Posted May 11, 2011 Yeah, brilliant news, if not for that I now feel like a complete idiot, haha My OMP is now firing up fine, although I believe I accidentally pretty much did a cold boot in the midst of battery handling and whatsit, not realising what I was doing - whoops, bye-bye data! Sound seems a little weak, so I might have to open her up again and investigate to see if it's anything I can fix... other than that, all is working well! Thanks everyone!

aplmak Posted November 3, 2019 Report Share Posted November 3, 2019 There are two caps that need replacement.. at 3.3uf@35v and a 100uf@4v.. one on each side of the logic board. They look like tantalum but they are cylinders in a black casing.. Quote Link to post Share on other sites
