Hi guys, a have a tablet chuwi hi10 pro. On motherboard i found two broken smd components sot23-5  
One of them is 4601 and I found that is ws4601 [WS4601 datasheet](https://datasheetspdf.com/pdf-file/1112875/WillSEMI/WS4601/1)

I have problem with the second one. Marking code is CP7T but i dont know what it could be.  
Does anyone know what is this ?

I had the same thing. Just replace the ws4601 and remove cp7t smd thing. It is something reverse protection or idk. The tablet works without it.  
I asked the chuwi support, i’m waiting for their answer.

I don’t dare to reinstall my hi10pro because of this again.

Maybe the big guys can help us out on this forum.

[HI10 plus CW1527 Black screen, no charging light](https://forum.chuwi.com/t/hi10-plus-cw1527-black-screen-no-charging-light/15018) non c’è alimentazione 1.7v dovuta al guasto del chip CP7, da verificare perchè si è guastato, condensatori della linea in corto, Io sono ancora in attesa del componente cp7 introvabile !
