LA-E801P Rev 2.0 motherboard schematic

This technical guide provides an in-depth look at the , a common board found in various Dell Latitude models (primarily the 5289 2-in-1 series).

Component Changes

: Rev 2.0 may use different MOSFETs or ICs, such as the PE642DT dual transistor , which are essential for accurate troubleshooting of "no power" issues. lae801p rev 20 schematic better

Rev 20 introduces:

A type-II compensation network with selectable zero placement. The new schematic includes pads for Cc (100pF to 1nF) and Rc (1k to 10k), allowing engineers to tailor transient response. LA-E801P Rev 2

, which should carry the 19V adapter voltage. If 19V is present here but the board still won't turn on, the issue may lie further in the charging circuit or the Super I/O. Where to Find the Schematic & Boardview Reliability: Enhanced ESD and EMI filtering
