Small Power IC for Lenovo A7-30 A3300

The Small Power IC on your Lenovo A7-30 A3300 is a secondary power regulation chip that manages power delivery to a specific subset of components — such as the camera module, display driver, or sensor array. The main Power Control IC manages overall power distribution across all systems. The Small Power IC handles a narrower scope — meaning its failure causes targeted failures in the components it supplies rather than total device failure on your Lenovo A7-30 A3300.

Symptoms include a specific hardware feature losing power intermittently or completely — for example the cameras shutting off under load, specific sensors becoming unresponsive, or a display function failing — while all other features continue to work normally on your Lenovo A7-30 A3300. These isolated power failures point to a small secondary power IC rather than the main PMIC.

Board-level diagnosis using a multimeter to measure the output voltage of the specific power rail managed by the Small Power IC confirms whether it is delivering correct voltage to its connected components. A missing or incorrect output voltage with correct input confirms the Small Power IC as the fault on your Lenovo A7-30 A3300.

No. This is a micro-SMD chip soldered onto the Lenovo A7-30 A3300 motherboard requiring hot air rework equipment, flux, and professional board-level repair skills. Only experienced technicians should attempt this repair.

Yes — a 7-day replacement warranty against manufacturing defects is included. An unboxing video is mandatory for all warranty claims. Once the chip has been soldered it is considered used and cannot be returned. For more information, check out SAHII's Return Policy.
