Guest satandole666 Posted August 31, 2004 Report Share Posted August 31, 2004 I just recently purchased my MPX200 and now it is having its first set of problems. It has turned itself off twice now, and it won't start up from the most recent one. I left the room and when I came back it was off. I hit the power button and it did nothing. I took the battery and SIM out a couple times and finally it started up again. Now it isn't working. A little background info, I just recently synced with my outlook and copied some music files to my SD card. It has been upgraded to 2003 and hasn't had any other problems. Any advice is welcome. Thanks. Quick update...I can get it to the hellomoto screen every time, but at most it will show the ROM screen and then shut down. I tried the hard reset (action key and power button, right?) and that didn't do anything. Link to comment Share on other sites More sharing options...
Guest flyaman Posted August 31, 2004 Report Share Posted August 31, 2004 From time to time, same problem for me. So I take the battery out, the simm card out, I wait 1 minute, then I reinstall the card and battery. Very often I start my phone, identify mysefl with the PIN, then it restarts automatically, and I do again the authentification :-D Link to comment Share on other sites More sharing options...
Guest awarner [MVP] Posted August 31, 2004 Report Share Posted August 31, 2004 Your problem sounds more like you have a dead battery. Try giving it a good charge for a few hours before powering it on again. Link to comment Share on other sites More sharing options...
Guest satandole666 Posted August 31, 2004 Report Share Posted August 31, 2004 I charged it over night and it still doesn't work. Right now it is plugged into the charger and nothing is showing on the external window. Sometimes it does, sometimes it doesn't. Edit: I just checked the SIM by putting it in my old phone and it works fine. I looked at batteries on eBay and they are REALLY cheap. Is there something I should know about them? The few I looked at say new factory replacement. Link to comment Share on other sites More sharing options...
Guest dpquez Posted August 31, 2004 Report Share Posted August 31, 2004 I found out the best way to install a new battery(before hard reset)is to keep turning on the phone until nothing shows up. Took me about 30min of doing this before it was completly dead. Then charge it for about 2 days then do a hard reset. After doing this I average about 76hours of standby time.

Guest squall Posted August 31, 2004 Report Share Posted August 31, 2004 i would not recommend this! the phone battery is designed such that if its ever completey empty it wont takea charge again! Link to comment Share on other sites More sharing options...
Guest awarner [MVP] Posted August 31, 2004 Report Share Posted August 31, 2004 Never fully discharge the battery!!!!! you will damage it. Li-ion batteries are not like Ni-cd and suffer from memory loss. they prefer to be topped up on a regular basis with a decent long charge once in a while.

Guest satandole666 Posted August 31, 2004 Report Share Posted August 31, 2004 So is everyone in agreement that I should get a new battery? These non-OEM batteries on eBay, are they reliable? Link to comment Share on other sites More sharing options...
Guest awarner [MVP] Posted August 31, 2004 Report Share Posted August 31, 2004 The OEM battery I have as a spare is not as big so it does not last as long. Link to comment Share on other sites More sharing options...
Guest satandole666 Posted August 31, 2004 Report Share Posted August 31, 2004 EDIT awarner please refer to site rules before posting links. Has anyone else had a similar problem? I think this might be what has happened to me, but since I bought my phone used and it has 2003 on it I think I might be screwed. Link to comment Share on other sites More sharing options...
Guest satandole666 Posted August 31, 2004 Report Share Posted August 31, 2004 I got it to turn on (WOW) and the battery was COMPLETELY dead. It was full the other night before it turned itself on. I'll keep you guys posted, but for now it looks like I have to buy a new battery. Edit: The battery is almost fully charged now. I'm still going to get a new one. How the hell did it drain completely when I always keep it on the charge when I am not using it? Link to comment Share on other sites More sharing options...
Guest bigfootpete Posted September 2, 2004 Report Share Posted September 2, 2004 Never fully discharge the battery!!!!! you will damage it. Li-ion batteries are not like Ni-cd and suffer from memory loss. I disagree - the main thing with Li-ion batteries is that they don't have a memory. I regularly - and sometimes unintentionally discharge the battery fully and it still produces the same results - two/three days standby max... Although I think the very first charge is important...

Guest Smokes11 Posted September 2, 2004 Report Share Posted September 2, 2004 When I first received my MPx200 I had this....soemtimes the battery charge would show.....sometimes not. Finally found that not all the connectors were contacting the battery fully.... a little waggle with a pair of plier and hey presto....no more problems. Maybe this will help. Meanwhile....Ive been messing with some of the OS files regarding MMS and now Icant send SMS or open received SMS.....has anyone found a 'fix it 'file for the 2002 operating system?

Guest awarner [MVP] Posted September 2, 2004 Report Share Posted September 2, 2004 I disagree - the main thing with Li-ion batteries is that they don't have a memory. Agree on memory loss as that is exactly what I said, but if you fully discharge a li-ion battery you can screw up the chemical composition of it and kill it's internal circuitry. It's hard to fully discharge it on the phone but it can be done. Link to comment Share on other sites More sharing options...
Guest Osiris Posted September 4, 2004 Report Share Posted September 4, 2004 I guess were talking about two different kinds of depletion here. But my Nokia 7650 ran on Li-on battery and I was told by the Nokia care rep to completely deplete it from time to time. Deplete it as the guy above did, keep turning it on until it doesnt even have enough power to turn on. I use to do that from time to time, and never had any dramas with the battery.

Guest awarner [MVP] Posted September 4, 2004 Report Share Posted September 4, 2004 NOOOOO!!! We are talking about the same thing. The Nokia guy knows about his phones but is obviously clueless when it comes to battery management, unfortunately some web sites are also misinformed which adds to the end users confusion. It is only the older style batteries ie Ni-Cd and Ni-mh that needed to be fully discharged as they did suffer from memory loss. Li-ion batteries still get memory loss but it is much less pronounced. It is always suggested to replace your battery afer a year use as it's efficiency will start to reduce. Figure 1 shows an ultra-low-power, precision undervoltage-lockout circuit. The circuit monitors the voltage of a Li-Ion battery, disconnecting the load to protect the battery from deep discharge when the battery voltage drops below the lockout voltage. Storing a battery-powered product in a discharged state while the battery is low puts the battery at risk of being completely discharged. During the discharged state, current to the protection circuitry also discharges the battery. If the battery discharges below the recommended end-of-discharge voltage, the battery performance degrades, cycle life shortens, and the battery dies prematurely. In contrast, if the lockout voltage is set too high, the maximum battery capacity isn’t realized. The low-battery mode of operation is indicated when, for instance, a cell phone automatically powers down after the battery-low indicator has been flashing for some time. If the phone is misplaced in this condition and found months later, the protection circuitry shown in Figure 1 won’t over-drain and damage the battery. That’s because the protection circuitry takes less than 4.5 µA of current. At this low current, the time taken by the Li-Ion battery to reach its end-of-discharge voltage is greatly extended. For other protection circuitry that typically requires higher currents, the rate of self-discharge is faster, allowing the battery voltage to drop below the safe limit in a shorter time. Note that if the battery is allowed to self-discharge below the safe limit, the resulting capacity loss that occurs is unrecoverable. In other words you will damage your battery Thanks to the guys at Electronic Design www.elecdesign.com Link to comment Share on other sites More sharing options...

Guest awarner [MVP] Posted September 11, 2004 Report Share Posted September 11, 2004 I get 3 days standby, that is left on with little use. Link to comment Share on other sites More sharing options...
Guest TylerDurden Posted September 11, 2004 Report Share Posted September 11, 2004 Hi, just got mpx200 and it has 2002 on it, how do i upgrade to 2003 ..? thanks :?: A little background info, I just recently synced with my outlook and copied some music files to my SD card. It has been upgraded to 2003 and hasn't had any other problems. Any advice is welcome. Thanks. Link to comment Share on other sites More sharing options...
Guest awarner [MVP] Posted September 12, 2004 Report Share Posted September 12, 2004 Welcome to the site :) Not sure what your question is as you first say you are looking for 2003 then below you say you have it :? For the first part the 2003 ROM is not a legal piece of software and has been removed from the hosting site due to legal reasons. As it is ilegal please do not ask for links etc. Link to comment Share on other sites More sharing options...
Guest Montana Posted September 12, 2004 Report Share Posted September 12, 2004 I have had the same problem that you did except for that fact that mine never turned on for a day so i left it on the USB charger for about 36 hours and when i came back i saw the battery indicator was full when it showed no indicator at all the day before, goofy stuff. just roll with it and the fone should come back on Link to comment Share on other sites More sharing options...
