An 88.8 KB PDF labelled as a schematic with the code 70mt160p. Nothing in the name identifies a laptop, board maker or revision, so the document has to be opened to learn its exact subject. The format of the code suggests a part number for a power semiconductor or similar component, making it useful mainly for checking pin functions and voltage or current limits. Any PDF viewer will display it. Verify the exact part marking on the hardware before choosing a replacement from it.
