• Brand / Model: Toshiba Satellite L500
• Manufacturer: Compal
• Board Number: LA-4982P (KSTAA)
• Architecture: Intel Core 2 Duo / GM45 / PM45

Common Chip-Level Faults & Repair Notes

If you're troubleshooting a dead Toshiba L500 / LA-4982P, consider these frequent issues:

• NEC/Tokin Capacitor (Proadlizer) Failure: This era of Toshiba laptops is notorious for NEC/Tokin capacitor degradation under the CPU socket. Symptoms include the laptop shutting off abruptly under load, freezing, or only running on battery power. Replace it with 4x 330uF Tantalum capacitors.
• No Display / Black Screen: Often caused by a corrupted BIOS or a failing Northbridge (GM45/PM45). Try flashing a clean BIOS first (provided below).
• DC Jack / Power Issues: Check the input MOSFETs and the main 19V rail near the charging IC for shorts.

• Graphics: ATI Mobility Radeon (M82 128/256MB or M86 256/512MB)

Common Chip-Level Faults & Repair Notes

If you're troubleshooting a dead or faulty Toshiba A350/A355 (LA-4571P), keep these points in mind:

• Graphics Artifacts / No Display: The dedicated ATI graphics chip (M82/M86) is the most frequent cause of failure on this model due to thermal cycling. Reflowing or replacing the BGA chip is the standard solution.
• NEC/Tokin Capacitor Issue: Like many Toshiba laptops of this generation, this board may suffer from a failing NEC/Tokin Proadlizer under the CPU socket. If the laptop crashes randomly or shuts down under load, replace the NEC/Tokin with 4x 330uF Tantalum capacitors.
• No Power: Verify the 3.3V and 5V Always-On rails. Check the main 19V rail and the DC jack connector which can become loose over time.

Acer Aspire 5742-compal-la-6582p-pew7181-uma

Acer Aspire 5742 Motherboard (Compal LA-6582P / PEW71) Schematics & BIOS Bin

Motherboard Specifications

The Compal LA-6582P (PEW71 UMA) is a motherboard designed for the Acer Aspire 5742 series laptops. This specific variant is an UMA architecture (Unified Memory Architecture), meaning it relies on Intel integrated graphics rather than a discrete GPU. It supports Intel Core i3 and i5 processors (Arrandale) with DDR3 RAM support.

• Board Model: Compal LA-6582P (PEW71)
• Graphics: UMA (Intel Integrated Graphics)
• Supported Models: Acer Aspire 5742, 5742Z
• Platform: Intel Arrandale

Common Chip-Level Faults & Repair Notes

When troubleshooting a dead or no-display Acer Aspire 5742 (LA-6582P board), check these common failure points:

• No Power (19V Short): Verify the main 19V rail. Shorted ceramic capacitors near the CPU VRM are a common issue on this board.
• 3V/5V Standby: Check if the standby IC is generating the ALW 3.3V and 5V. If 3.3V is missing and the IC is hot, the KBC/EC may be shorted.
• Turns on but No Display: Often caused by a corrupted BIOS or issues with the CPU core voltage (VCC_CORE). Reflashing the BIOS/EC is the recommended first step.

Common Chip-Level Faults & Repair Notes

When troubleshooting a dead, no-power, or no-display Acer Aspire 4740/4745/5745G (LA-5681P board), verify the following common failure points:

• 19V Main Power Rail (VIN): Check the main input MOSFETs (PQ1, PQ2) and the charging IC for shorts or failure to pass 19V to the system.
• 3V/5V ALW Standby: Ensure the Always-On 3.3V and 5V coils are generating voltage before the power button is pressed. A missing 3.3V rail often points to a faulty standby IC or a shorted EC/KBC.
• No Display / Black Screen: Very common on older Arrandale platforms. Often resolved by a clean BIOS flash using an SPI programmer (like RT809F or CH341A) or by addressing the discrete GPU if present.
