==Problem description==
Fixing an issue with the 910-13IKB Lenovo Yoga where it does not turn on nor charge.
[[File:Placeholder image.jpg|thumb|923 7HRZ ISL9237 (Figure 1)]]
==Symptoms==

*Not turning on
*No 19V on motherboard
*Not charging

==Solution==
If charging the battery manually (voltage injection) allows the laptop to power on then the chip on motherboard marked 923 7HRZ (ISL9237) Figure 1 is shorted. This chip monitors system power and talks to the SMBus. Replacing the ISL9237 fixes the problem.
