so my dsi was working fine, i did leave it unplayed for about a few months but ive done that before and it always worked fine. so when i picked it up recently it still had battery and i played it some before putting it down. i picked it up the next day it didnt have enough battery to turn on so i went to chage it. i had a issue where it was giving me a blinking light while charging, i moved the charging tip a bit to where it then turned to a solid light but still wasnt turning on which i didnt even think was possible. so after leaving it overnight a few times to see if it just needed to charge for a while, i gave up. after that a couple weeks later i tried t plug it in and now its giving me one single light and turns off after. im not sure what to do at this point

My favorite method for finding the reason for such problems: The Process of Elimination:
  • Try your charger on another DSi(XL) or 2|3DS(XL) console to verify the charger is working
    • The other way round: Try another, known good, charger on your DSi
  • Charge your battery in another, known to be working, DSi to verify if your battery accepts charge
    • Provide a know to work battery in your DSi and see if it charges
After these tests you should know if the charger, the battery or the console has a problem.
=============

For the case the trivial replacement of battery/charger doesn't help; Possible reasons for the console itself not charging (see photo below):
  • Charging port damaged or loose connection/bad solder joints
    • Measure voltage on the inner solder joints with charger connected. Gently push the connector in all directions to see if it starts charging when applying a little(!) force. Replace connector if needed
  • Fuse F1 blown
    • Measure continuity. If the fuse is blown, replace it (and hope it doesn't blow right away). Be warned this thing is tiny. Not an easy solder job. You can also bridge the fuse: Much easier, but dangerous for the board. I advise against bridging fuses.
  • Filter(?) EM1 defective
    • No idea how to check it. Measure voltages of a charging working unit and compare it to yours. I have no idea what part this is; I would use a donor board to get one
  • Power board not correctly connected(and I think the power board has a fuse as well)
    • See if you get battery voltage on the white connector at the bottom – the small metal points next to (+) and (-) markings on the mainboard.
  • Charging IC defective
    • Same as EM1. Last thing to do. If everything else is okay, I would suspect this little chip. Requires rework station (hot air)
F1 is right below the charging port, EM1 left to F1 and the charging IC is inside the red box in the following picture: (The photo is part of a blog entry I posted months ago, so ignore the text)

can you play with the chager connected?

you may need to replace the battery imo.
the dsi doesnt turn on at all, ill edit the original post to put that in there. because of the different statuses over the past month or so i dont think it is the battery but i also havent replaced either
