Replacement Motherboard for Chromebook 5190

This Dell motherboard carries the model number 17858-1 and matches the Chromebook 5190 platform. It integrates an Intel Celeron N3350 dual-core processor running at 1.10 GHz. The board arrives new and is intended for repair or upgrade of compatible units.

Thermals and Power on the N3350 Board

The low-power Celeron N3350 typically operates within a modest thermal envelope suited to fanless or single-fan chassis designs. On-board LPDDR4 memory at 2400 MHz contributes to reduced power draw compared with socketed alternatives. Normal workloads such as web browsing and document editing keep temperatures and acoustics well controlled.

Build Quality and Connector Implications

Soldered 4 GB LPDDR4 memory and 32 GB eMMC storage mean capacity cannot be expanded after installation. The board follows the Dell Chromebook 5190 layout, so existing mounting points, display cables and I/O daughter-boards align without modification. Verify the MPN PC1G3 against your service manual before fitting.

Questions about this item

How do I install the 17858-1 motherboard in a Chromebook 5190 and what step do people often miss?

Disconnect the battery first, then remove the bottom case screws, swap the board, and reconnect the battery before closing the case — skipping the battery disconnect risks shorting the LPDDR4 memory.

What maintenance or replacement will the on-board 4 GB LPDDR4 2400 MHz memory and 32 GB eMMC storage need later?

Both are soldered to the board, so they cannot be upgraded or replaced individually; if either fails the entire motherboard must be swapped.

What limit appears first on the Intel Celeron N3350 1.10 GHz dual-core under sustained load?

The 6 W TDP ceiling throttles the processor once temperatures rise, capping long-term performance before memory or storage bandwidth becomes a factor.
