HP ZBook Firefly 16 G10 RAM, SSD & Charger Compatibility

The HP ZBook Firefly 16 G10 is the larger, more powerful sibling of the Firefly 14, designed for professionals who want a 16-inch mobile workstation without compromise. With 13th Gen Intel Core i5/i7/i9 processors, dual M.2 SSD slots, and NVIDIA RTX A500 graphics, it delivers serious performance in a sub-2kg form factor. This guide covers all upgrade paths: RAM, storage, charging, and peripherals.

RAM Compatibility

Like its 14-inch sibling, the Firefly 16 G10 features 2 DDR5 SO-DIMM slots supporting up to 64GB total (2x32GB DDR5-5200). Most configurations ship with 16GB or 32GB standard. Upgrading RAM is straightforward and requires no tools beyond a soft plastic spoon for the access panel.

To upgrade: power off completely, remove the underside access panel (4–6 Phillips screws), push the white retention clips outward on each slot, and pull the old module at a 45-degree angle. Insert the new DDR5-5200 module at 45 degrees and press down until the clips snap into place. Kingston FURY Impact, Corsair Vengeance, and Crucial Ballistix DDR5 modules are common upgrades. See our DDR5 SO-DIMM compatibility hub for tested models.

SSD Compatibility

The Firefly 16 G10 is the first Firefly to offer dual M.2 2280 NVMe slots, both supporting PCIe Gen 4. This means you can have up to 8TB of storage (2x4TB SSDs) — double the capacity of the 14-inch model. Both slots are identical and hot-swappable.

To replace or add an SSD: locate both M.2 slots on the motherboard (usually marked), unscrew the small Phillips screw at a 30-degree angle, pull the old drive diagonally, and insert the new one at the same angle until it clicks. Tighten the screw. Many users upgrade one slot to a 2TB drive while keeping the 512GB factory drive in the second slot for dual-boot scenarios. Browse NVMe SSDs on Amazon — Samsung 990 EVO, WD Black SN850X, and SK Hynix P41 Platinum are professional-grade choices.

Charger Compatibility

The Firefly 16 G10 ships with a 65W USB-C Power Delivery charger as standard. However, depending on the configuration (CPU and GPU tier), some units come with 90W chargers. Both are USB-C PD standard, so any 65W+ USB-C PD charger is compatible. For heavy computational workloads, a 100W or 140W USB-C charger enables faster charging during use.

The Firefly 16 G10 has no barrel connector — USB-C PD is the sole charging method. This makes multi-device charging simpler on the go. A 140W USB-C PD charger is overkill for this model but will charge it in the same time as the 90W version while also powering a desktop dock or external monitor.

Dock & Thunderbolt 4 Compatibility

The Firefly 16 G10 includes 2x Thunderbolt 4 ports. Any Thunderbolt 4 or Thunderbolt 3 dock with 65W minimum pass-through charging is compatible. Recommended options:

• HP Thunderbolt Dock G3 — 120W charging, supports 2 external displays via DisplayPort, hot-swappable USB devices
• Lenovo Thunderbolt 3 Dock Ultra — Cross-compatible with TB4, 100W charging, excellent cable management
• CalDigit Thunderbolt 3 Dock Pro — Premium option with 85W charging and multiple video outputs for multi-monitor setups
• Budget USB-C hubs — Anker, Belkin, and Aukey USB-C hubs (with 65W PD) work fine for basic setups without needing full Thunderbolt bandwidth

Since the Firefly 16 uses USB-C PD charging (not a barrel connector), ensure any dock supports at least 65W pass-through power delivery so you can charge the laptop while using peripherals.

Frequently Asked Questions

Why two SSD slots on the 16-inch but only one on the 14-inch?

The larger 16-inch chassis has room for a second M.2 slot without increasing system thickness or weight meaningfully. This gives users much more storage flexibility — many choose to keep the factory 512GB drive and add a 2TB NVMe for projects, creating a fast dual-drive setup.

Can I mix and match different SSD brands in the two slots?

Yes. Both M.2 slots are identical, and the system will recognize any PCIe 4.0 NVMe drive in either slot. You can have a Samsung 990 EVO in Slot 1 and a WD Black SN850X in Slot 2 without any issues. The system will automatically detect and manage both.

Is the 4K display worth upgrading to?

For video editing, 3D rendering, and detailed CAD work, the 4K option (3840×2400) is worth the upgrade. For coding and office work, WUXGA (1920×1440) is sufficient and extends battery life. Both are matte, high-refresh 60Hz panels with excellent colour accuracy for workstation use.

How long does it take to upgrade RAM or SSD?

Total time is 10–15 minutes. Remove 4–6 bottom screws, unclip the access panel, unscrew and pull the old module (1 minute per slot), insert the new one (1 minute), and replace the panel. No tools other than a Phillips screwdriver needed.

Can I use the Firefly 16 G10 with a desk setup full-time?

Absolutely. Dock it via Thunderbolt 4 to a multi-monitor setup, add external keyboard/mouse, and it functions as a full workstation. The 16-inch 4K display is excellent for detailed design work. Just ensure your dock supports 65W+ pass-through charging so the laptop charges while connected.
