Nintendo Switch Lite missing capacitor (?) near USB

Nintendo Questions Nintendo Switch Lite

Hello :slight_smile:

I got Nintendo switch lite with a problem. When I bought it, it does charge with only 5v and 0.2A only with one side usb connected, when I rotate it, it doesn’t charge. I can see that somebody changes usb, so I make it once again. I didn’t connect to charger, because I see one missing element, and one rotated. Can somebody help me to identify and tell me what I should order? It’s located backside, under usb, in 5mm line, there is probably an fuse and capacitor.

I don’t have probably enough posts here to to add an photo :frowning:

  • The USB C port looks melted inside beside the ground holes are not propper filled with tin.
  • The missing part is a 0805 10µF cap. The Switch will turn on without the cap. But should be there in regular use.
  • The little moved part is a fuse. If continuity is given the fuse is still ok.
  • The moved square shaped part is the fuel gauge chip with 3x3 BGA. Without prooper connection to its pads the Switch will not turn on.

About that USB I know, I already ordered it :slight_smile: Somebody did bad job here, I desoldered it to check if all soldering points are on place and soldered it again without soldering ground points, just to check that it works. About all parts which are moved, I will try to correct them, and order cap which parameters You give me :slight_smile:

Big thanks!!

Today package arrived, so I immediately sit for it. Job done, but… it doesn’t powered on, I checked fuse and it doesn’t have continuity :frowning: New USB-C and cap soldered.

So the fuse now is blown?
Do you have a short on the m92t36 side?

I would reball or change the fuel gauge chip to be sure its nine bgas are fine.

Yup, I take out that fuse. Need to order new one. Tomorrow I will check that chip :slight_smile: I think that somebody changed or reflow it before, there was flux in multiple places on board when I opened it. Do You know what is that fuse to order it?

I would use a 0402 3A fuse.
For testing you can bridge the fuse with a little wire.

I can’t find polyfuse 3A with 0402 size, only fuses which blows, minimal size of polyfuse are 0603. Do You think that 0603 can sit there, or it’s better to use one time fuse 0402?

I don’t think it is a polyfuse. I would use a regular fuse.
