Sony d-ne900 gumstick battery not charging - Sony Cell Phones

If it does not charge, the issue lies with either the charger or the battery.

If thelaptop battery is more than 3 - 4 years old then the battery could be worn out.Rechargeable batteries have a finite number of charge and discharge cycles andwill lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up at all. OR Thebattery shows a 100% charge but when the adapter is disconnected the batterydrops off to zero capacity in a very short time. If the battery drops to anunacceptable charge level then the battery needs to be replaced.

Your batteries may be weak replace them, regadless of what the recorder says. The gumsticks ar good for a year or two at best.

Unfortunately if it's getting power but not responding there is little that you can realistically do. When you state "Power is connected ok" I presume that this means you have already tried using the gumstick rechargeable battery (which doesn't last forever, BTW), and also the charging stand. If you have tried both of these, then it's clearly not an obvious fault such as a broken power input socket. You can also try connecting the optional external dry battery case, but this was an optional item with the N-710 and rarely purchased by users, or you can try disconnecting the ac adaptor from the charging stand and connecting it directly via the socket on the player marked DC IN 3v.

The fault is likely a really simple one but the MZ-N710 and almost all other portable MD players were never designed to be repaired and consequently are really difficult to dismantle without causing more damage. When I used to sell these products I was told by the Sony servicing centre that for all but the most minor issues warranty claims were dealt with by destroying the returned unit and sending the customer a complete replacement.

Spare parts were not commonplace when the units were a current model, and now they're as common as freshly laid dodo eggs. Your only realistic fix is to replace the unit.

This may sound negative, but it's not: because MD is now an obsolete format there are millions of perfectly good units lying unused by those who have upgraded. Except for the later and far rarer HiMD models and also flagship regular units like the MZ-N910, almost everything else is near worthless so folks tend not to bother with selling them. As a result it's quite easy to pick up MD equipment for free via your local FreeCycle and Freegle groups; apart from my own MZ-N910 (still in regular use and has a far superior sound quality to any iPod) every piece of MD gear I own was obtained for free, usually with loads of minidiscs as well. Don't be too choosy about what you may be offered as most of the Sony NET MD players (any MZ-N model) can be easily hacked to give them most of the features of the flagship MZ-N910.

If you do end up recycling your MZ-N710, then keep all of the accessories as they can be used on other players which you might acquire.

I hope that my answer has been of use even if you cannot fix your player. Please take a moment to rate my answer.

I've deliberately avoided answering your question for a few days to see whether someone else had located a gumstick battery charger, but clearly they have drawn a blank as well. They were never a common item even when Sony sold them new.

You may wish to do as I do: I use broken MD players as chargers. There are millions of MD units lying unused, most are worthless now and many are broken (typically the fatal TOC error). As a result it's easy to get them for nothing on local FreeCycle and Freegle groups and often they come with spare discs, batteries and other accessories. best of all, most of them are still in working order so you may even end up with a free upgrade. Every bit of MD gear I own has come from FreeCycle and Freegle except for my superb MZ-n910 which remains in regular use.

As luck would have it, I was about to hit the "Post Solution" button when I found this one on eBay. It wasn't there when I last looked! it will hold two gumstick batteries.

The "gumstick" battery you're referring to is like ALL other rechargeables in that it does not last forever. If you're certain that the charger is working then just buy another battery.

If you're in the UK then I highly recommend the Small Battery Company. Be careful if purchasing from Amazon Marketplace or eBay as there are plenty of underperforming fakes around.

my phone is the same model and did this but when i charged it, after about an hour it would come up with 'charging error stop ' and when i unplugged it, it hadn't even charged at all. and then the other day it just wouldnt charge, i plugged it in, it said it was charging but it wasnt. in the end, it worked by keeping the phone switched off and charging it while i was turned off. so try that, if not then i really dont know sorry

it might be it might just be a fulty charger

You can get a battery for the sony ericsson P990i mobile phone here - sony ericsson p990i battery

Here is a replacement source

The batteries are covered under warranty for three years. Sony batteries are know for not keeping a good charge after a few years.

If there not holding a charge, they wouldn't appear on the LCD screen at all. I the AC power is working fine, then that probably isn't the source for not getting a charge.

You could try lightly scraping the contacts on the battery and see if that makes a difference and recharge them.
