Lae791p Rev 20 Schematic Better

Intel Skylake-U or Kabylake-U processors (frequently Core i3/i5 or Celeron/Pentium variants). Memory: Single or dual-channel DDR4 SO-DIMMs.

Once +19V stabilizes across the main current-sensing resistor, it feeds the dual-channel step-down Pulse Width Modulation (PWM) controller. This controller generates:

For effective troubleshooting, the CSL50 LA-E791P Rev 2.0 PDF includes several vital diagrams:

Websites like and AliSaler often provide direct download links for boardview files (usually in .CAD format) and BIOS dumps. For example, a free boardview for the HP 250 G6 LA-E791P is available for download, though it is prudent to cross-reference the BID number (usually 08328 for Rev 2.0) to ensure you have the exact match for your motherboard revision. This controller generates: AMD Radeon R17M discrete graphics

: If you find a true short circuit (near 0 ohms) on a high-voltage rail like +19V , set your lab bench power supply to a safe, low voltage (e.g., 1V) with a current limit of 1A to 2A.

: Schematics are usually arranged by power domains. For the LA-E791P, look for pages labeled "Power Sequence" or "System Block Diagram" first. This tells you which voltage rail (e.g., +3VALW, +5VALW, +VCC_CORE) activates first. : If you find a true short circuit
