Technical Summary

This Quanta Computer Inc. QL4 NB motherboard schematic, dated October 9, 2009, details a platform supporting Intel Auburndale 35W or Clarksfield 45W CPUs paired with an Ibex-M PCH. The graphics subsystem features N10P-GE or N10M-GE GPUs with Switchable Graphics capability, supporting both discrete and UMA configurations. System memory is provided by two DDR III SODIMM slots supporting 800/1066 MT/s. The charging architecture is managed by an ISL6251AHAZ-T system charger. Power regulation is handled by multiple ICs including the ISL6288 for CPU core, RT8208A for VGA core and VCCP, RT8207 for DDR_VTERM, RT8206B for system power, RT8204 for PCH 1.05V, and RT8152A for UMA GPU core. Wired networking is provided by an AR8131(M) Gaga LAN controller, while wireless connectivity uses an Atheros AR5B91 module. The clock generation is handled by an RTM875N-632-GR clock generator in a TQFN32 package.
