Hacking Hardware OLED Picofly: sleep mode battery draining + Joycon jiggle

[Eds05]

Hello Guys,

I repaired another OLED switch, this time a Zelda edition, but in sleep mode the joycons are jiggling and the battery is draining like hell.

What I already tried:
- I swapped the MB in another oled console and its the same,
- same with another joycons,
- same with different modship (instinct nx and picofly),
- same in CFW or OFW,
- same if I restore the emmc,
- same in airplane mode.

This is what I repaired on this console:
- broken CLK line
- screen connector replaced
- permanent dat0, I reballed 3 times the emmc to try to get rid of this issue
- CMD resistor replaced

On this console the instinct-nx was taking a lot of time to gitch the console, so I replaced it by a Picofly.

But to not have a slow emmc mode I had to add +47ohms on the CMD point, and +3x47ohms on the dat0 point.

I did maybe 30 oled modchips, with only picoflys. Usually I only add +47ohms on the CLK point to not have a emmc slow mode.

I find nothing on internet about this issue.

What could cause this issue ?

Thank you

What do you mean the JoyCons are jiggling?

 

[Eds05]

They are doing little vibrations, briefly and randomly.
Only in sleep mode.

Are the Joycons charging? Do they work wirelessly? Check right joycon

Hello,

Yes everything is working regarding the joycons.

But I noticed something, If I launch Lakka, when I turn off the switch (sleep mode), the switch wakes up few seconds after. Maybe on the switch OS the console is partialy in sleep mode. I mean, the OLED screen is off etc... but not the Tegra or something else. Cos if I put the switch in sleep mode, the APU is a bit warm even after few hours, really noticeable if the console is in his case.

I think I have an hardware issue. Which controller is managing the sleep mode ? I would like to replace it.

Hi, have you checked for shorts beneath the SoC? In Lakka, the Switch can wake itself up if the power button gpio pin is shorted. The joycon issue might be related

I just removed the APU to redo the clk line, it was almost covered by the APU after a nuke bomb on it. And I saw anything broken except the clk. I also rebuilt the cmd line and change an almost broken sp2 capacitor on the APU (could be this).

Im waiting the stencil and some resistors to reball the APU, put a new cmd resistor, change the oled screen connector and it should be good

Hope this standby mode will be fixed

About the joycon, even with the sliders disconnected from the main board I had the sleep mode issue.

My console drains about 7% per hour, in sleep mode

Thanks for your reply. Interesting your case. I should receive everything to reball the APU this week and Im gonna see if the fan is spinning too.

Start the game so the ventilators start spinning. Close the game and lock the console. watch the fan, if it does not stop spinning then disconnect the joycons. But I'm sure we have 100% the same problem, we need to unite and find a solution. We need measurements of all the major components from a working board.

It’s weird cos the calibration was happening each time the battery was dead because of the issue ahah.

On my side I redo the traces for clk, reballed the APU, change sp1 and sp2 capacitors, CMD resistor, change de sliders connector, the oled connector. Everything is working good exept on lakka I still can’t turn the console in sleep mode.

Im doing tests now let see. I keep u in touch.

Btw I also tried for the fan and mine turns off.

In one night, my switch lost 7% and the other one lost 0% It looks better but the problem is not solved.

I found this video


At 42:20 he’s fixing a sleep mode issue.

And regarding this video, replacing the bq chip should fix it.


Im gonna try.

I didn’t change the bq but it seems fixed. I have 81% after 16 hours (I started at 100%) and I played a bit.

 

[Eds05]

Last update : It seems fixed cos this night I lost 0%. But, I still can’t go in sleep mode in Lakka.

How do you fixed it? Just cleaning?

Right Joycon . Long press home to get the menu to sleep . But idk if it's the joycon . Does it do this while connected in console and handheld mode ? Does it do it when using Atmosphere or just Lakka ?

I reflowed the APU to fix the CLK trace and cleaned the board.

Today its still fixed. I have no more issues with this console
