1.1a 24v Schematic [portable] | F4901

When a laptop like the Acer Aspire 5560G experiences a "black screen" but still powers on, technicians often check the F4901 fuse for continuity. If this fuse is blown, it breaks the circuit for the screen's backlight.

Such as the ISL6267 or RT8207 for various voltage steps. f4901 1.1a 24v schematic

On these laptop boards, this component is often a fast-acting fuse protecting the backlight circuit or a specific low-power voltage rail. F4901 (Fuse 4901) Current Rating: 1.1 Amps (1.1A) Voltage Rating: 24 Volts (24V) Common Use: Backlight power protection for LCD/LED panels. Troubleshooting with the Schematic When a laptop like the Acer Aspire 5560G

The identifier refers to a specific silk-screened marking found on the motherboard of several laptop models, most notably the Acer Aspire 5560 and 5560G . In technical contexts, "F4901" typically designates a surface-mount fuse (F) on the board's power rail, rated for 1.1 Amps and a maximum voltage of 24 Volts. Motherboard Context On these laptop boards, this component is often
