Wistron EA40-HW ULT schematics, revision R1, packed in a RAR archive of about 1.7 MB. HW most likely refers to an Intel Haswell platform and ULT to its low-power CPU package, but the retail notebook is not named. The PDF set inside shows the power tree, regulators, charging stage and signal paths, so you can trace a missing rail or find the source of a short. Wistron builds boards for several brands, so check that EA40-HW and the revision printed on the PCB match before relying on these pages.
