HP RTL8191SE 593533-001 Half Mini PCIe Wi-Fi adapter

SKU CH-Q4B1-PERAN

Half Mini PCIe wireless adapter adds 802.11 bgn Wi-Fi at 2.4 GHz to compatible HP laptops

  • TypeM.2 Wi-FI Adapter
  • 11 b/g/n Wi-Fi for reliable 2.4 GHz connectivity
  • Half Mini PCIe form factor fits compatible HP laptop slots
  • Genuine HP part 593533-001 ensures direct compatibility with listed models
  • Realtek RTL8191SE chipset delivers standard wireless networking performance
  • Supports HP CQ56, G62 and CQ62 series notebooks

Genuine HP Half Mini PCIe wireless card

The HP RTL8191SE 593533-001 is a factory-original wireless adapter built for select HP notebooks. It restores 802.11 bgn connectivity on compatible CQ56, G62 and CQ62 chassis. Buyers needing Bluetooth, 5 GHz support or a full-size Mini PCIe bracket cannot use this card.

Fits half-height Mini PCIe slot on listed HP models

Installation requires an available half-height Mini PCIe socket and the two antenna leads already routed in the supported laptops. The card draws power directly from the slot so no extra cabling is needed. Systems without the matching whitelist entry or missing antenna cables will not recognise the adapter.

Maintains steady 2.4 GHz throughput under load

The RealTek RTL8191SE controller sustains 802.11n link rates during extended transfers without thermal throttling. Connection stability holds across typical indoor distances at the 2.4 GHz band. Heavy concurrent traffic or dense RF environments may still reduce practical bandwidth.

Questions about this item

Does the RTL8191SE adapter throttle speed during long downloads on the 2.4 GHz band?

The Realtek RTL8191SE runs on IEEE 802.11 bgn at 2.4 GHz and may reduce throughput under sustained load due to thermal limits of the Half Mini PCIe form factor.

How loud or hot does the 593533-001 card get when running all day inside an HP laptop?

The card has no fan; heat stays low but the slot area can warm up during continuous traffic on the 2.4 GHz band.

Which antenna cables must already be present in the HP CQ56 or G62 for this Half Mini PCIe card to work?

The laptop needs two built-in antenna leads that connect to the card's U.FL connectors for 802.11 bgn operation.
