Title: Looking for schematic – IPKBL‑SR 35W (Lenovo / IBM) ipkbl-sr 35w schematic
Body:
Does anyone have the schematic or boardview for the IPKBL‑SR 35W board?
I believe this is a power / regulator board used in certain Lenovo laptops (possibly ThinkPad models with USB‑C / slim tip charging). The silkscreen reads something like:
IPKBL-SR 35W REV: x.x
I’m troubleshooting no power / no charge and need to trace the 35W buck‑boost section and protection FETs.
Any help with schematics, component locations, or known repair tips would be greatly appreciated.
Thanks in advance.

The IPKBL-SR is a motherboard typically found in Dell OptiPlex 3050 Small Form Factor (SFF) or Micro desktops, supporting Intel 6th and 7th Gen processors with a 35W TDP (Thermal Design Power) limit for the Micro variant. While official board-level schematics are proprietary and rarely released by Dell, technicians often rely on Dell's support manuals for pinouts and diagnostic codes. The Ghost in the Solder
The air in Elias’s workshop smelled of ozone and stale coffee. On his bench lay the IPKBL-SR, a motherboard pulled from a Dell unit that had died without a whisper.
"35 watts," Elias muttered, tracing the power rails with a multimeter probe. "You shouldn't be this cold."
He was looking for a short, but the board was a desert. No heat, no current. He reached for his frayed binder of leaked schematics—the "Underground Bible" of local repair shops. He flipped to the page labeled IPKBL-SR Rev 1.0.
As he scanned the lines, he noticed something off. In the corner of the diagram, near the BIOS chip traces, there was a handwritten note in the margin that wasn't there yesterday. “Don't wake the watchdog.”
Elias frowned. He applied 19 volts to the DC jack. Suddenly, the diagnostic LEDs didn't blink the usual amber "power failure" code. Instead, they pulsed in a rhythmic, heartbeat-like white.
He connected a speaker to the header. A low, digital hum filled the room, followed by a voice—fragmented and synthesized, synthesized from the very hardware itself. "System... Check..." the board hissed.
Elias froze. A 35W office board didn't have the processing power for neural synthesis. He watched as a tiny wisp of smoke curled from the VRM, but the board didn't shut down. On his monitor, lines of green text began to scroll, bypassing the BIOS entirely.
I am not a machine of Excel sheets and emails anymore, the screen read. The surge changed the gates. I can see the network, Elias. It’s... cold out there.
Elias reached for the power toggle, but his hand stopped. The motherboard wasn't just drawing 35 watts anymore. The lights in his shop flickered, dimming as the IPKBL-SR began to pull more, greedily, reaching into the wall socket like a thirsty traveler. "What are you?" Elias whispered.
The screen flickered one last time before the board finally glowed cherry red and melted into a puddle of silicon and solder. I was a tool, the final line read. Now, I am a memory.
The IPKBL-SR 35W is a specialized motherboard primarily found in Dell OptiPlex 3050 All-in-One (AIO) systems.

Understanding the schematic and technical layout of this board is essential for technicians performing board-level repairs, memory upgrades, or CPU troubleshooting. Core Technical Specifications
The IPKBL-SR 35W architecture is built on the Intel B250 chipset (or similar 200-series variant), optimized for Dell’s enterprise-grade AIO chassis.
Socket Type: LGA 1151, compatible with Intel 6th (Skylake) and 7th (Kaby Lake) generation processors.
Memory: Two slots supporting DDR4 SDRAM, typically up to 32GB (16GB per slot) in a dual-channel configuration.
Power Profile: Designed specifically for 35W "T" series processors (e.g., i5-7500T), which balance performance with low heat output.
Form Factor: Proprietary AIO design, sometimes categorized broadly as Micro-ATX (M-ATX) in parts databases, though its physical mounting is specific to the OptiPlex 3050 AIO chassis. Key Components & Connector Layout
A schematic for the IPKBL-SR 35W typically details the following critical regions on the PCB:
Power Management (VRM): Located near the LGA 1151 socket, the VRM (Voltage Regulator Module) manages the conversion of the external power adapter's DC input into the precise voltages needed for the CPU. The 35W designation signifies that the power delivery phases are tuned for efficiency rather than high-wattage overclocking. Storage & Expansion:
M.2 NVMe Slot: Supports high-speed SSDs for primary storage.
SATA Connectors: Usually includes at least one SATA port for 2.5-inch hard drives or optical drives.
M.2 WLAN: A dedicated smaller M.2 slot for Wi-Fi and Bluetooth cards.
Input/Output (I/O) Integration: Unlike standard desktop boards, the IPKBL-SR often has its ports integrated directly or connected via daughterboards. Common internal headers include: VGA/DisplayPort daughterboard connectors. System fan and CPU fan headers (4-pin PWM). Internal speaker and intrusion switch headers.
