La-e801p Rev 2.0 Schematic Site

If you are currently working on a repair, what specific or missing voltage rails are you encountering on the board? Knowing if the laptop has experienced a liquid spill or a sudden power surge can also help narrow down the issue.

: Information on the battery charging IC and the DC-in negotiation (USB-C Power Delivery). Memory : Wiring for integrated LPDDR3 RAM.

Because these are proprietary documents, they are rarely hosted on official Dell or Compal websites. Most technicians find them through: la-e801p rev 2.0 schematic

: Available in both UMA (Integrated) and Discrete (R17M-M1-30 or R17M-M2-50) configurations using PCIe 3.0 (8Gb/s). Power Rails : Main input: 19V . System rails: 3.3V and 5V (Always-on). DDR Power: 1.2V . Common Issues & Repair Insights

When diagnosing a "no power" or "dead" laptop, you must start at the power supply chain. The schematic provides the "road map" to follow the voltage: If you are currently working on a repair,

If the schematic shows a short to ground on a main rail like +1.0V_MCP , use the schematic to find a safe injection point to identify the heating component. Safety Warning

The main schematic is typically provided in PDF format , which can be opened with any standard PDF reader like Adobe Acrobat. A Boardview file is different; it comes in formats like .CAD , .ASC , or .BRD . You will need specific boardview software, such as OpenBoardView (free) or BoardViewer , which are widely available for download on major repair forums. Memory : Wiring for integrated LPDDR3 RAM

When tracking down missing enable signals (like EN or SHDN on PWM chips), use the schematic to verify the resistors making up the voltage divider. A shifted value in a mega-ohm resistor can prevent a power rail from starting up.

The LA-E801P Rev 2.0 schematic is an essential document for laptop technicians and electronics hobbyists tasked with repairing the HP 15-BS and similar series laptops. This motherboard, often featuring Intel Kaby Lake processors, uses a complex design requiring detailed diagnostic maps to pinpoint issues like no-power, no-display, or charging failures.
