Dell Pro 14 Plus PB14255 GH77W – Complete Review & Components Breakdown

Dell Pro 14 Plus PB14255 GH77W

AMD Ryzen AI 7 PRO 350 · AMD Radeon 860M · 32GB LPDDR5-7500 · 1TB SSD · 14.0″ 1200p IPS 60Hz · 1.582 kg
Mid‑tier Dell Pro business laptop with good build quality (aluminium + plastic), quiet fan, and cool operation. Features Wi‑Fi 7, Thunderbolt 4, SmartCard reader, and 4G upgradeable. However, the IPS display has poor colour gamut (56% sRGB) and dim brightness (~295 nits), RAM is soldered, touchpad has delay issues, keyboard is not user‑repairable, and CPU performance is below average for this chip. Priced around €1,630 (~$1,750)hard to recommend when competitors offer better screens and upgradeable RAM.

Display Panel – Dim 60Hz IPS, Poor Colour Gamut (Low Power Panel Recommended)

Panel model: LP140WU4 – 14.0″ 1920×1200 60 Hz IPS (matte).

SpecificationValue
Brightness~295 cd/m² (avg), peak 315 cd/m² – dim
Contrast1,260:1 – acceptable
Colour Coverage56.3% sRGB, 37.5% DCI‑P3 – very poor
Accuracy (uncalibrated)ΔE 6.0 avg, ΔE max 15.2 – poor
Accuracy (calibrated)ΔE 5.1 – still poor
Response Time (B‑W)21.1 ms – slow
Response Time (GtG)27.1 ms – slow
PWMNone detected – flicker‑free
Refresh Rate60 Hz – basic
FinishMatte – anti‑glare
  • Very dim display – only ~295 nits – poor for any use
  • Very poor colour gamut – only 56% sRGB
  • Slow response times
  • 100% sRGB Low Power panel available – highly recommended
  • No PWM – eye‑friendly
The display is a major weakness – dim, poor colours, and slowthe 100% sRGB Low Power panel is a must‑have upgrade.

Keyboard & Touchpad – Good Keyboard (Touchpad Delay Issues)

  • Keyboard: 1.5 mm travel – nice bounce, precise
  • White backlight (standard)
  • Enter key is small, no dedicated navigation keys
  • Keyboard is not user‑repairable
  • Touchpad: 12.5 × 7.3 cm mechanical – smooth surface
  • Touchpad delay after long pauses – driver issue
  • Plastic surface, not glass
The touchpad has an annoying delay issue after long pausesDell needs to fix this driver problem.

Ports & Connectivity – Decent (No Ethernet)

  • Left: HDMI, USB‑A 3.2 Gen 1, 2× Thunderbolt 4, SmartCard reader
  • Right: nanoSIM, 3.5mm audio, USB‑A 3.2 Gen 1, Noble lock
  • 2× Thunderbolt 4 – modern connectivity
  • 2× USB‑A – good for legacy peripherals
  • No RJ45 Ethernet – unlike competitors
  • Wi‑Fi 7 (Mediatek MT7925) – ~1,690 Mbit/s transmit on 6GHz
  • 4G upgradeable – antennas and SIM slot present
Connectivity is decent with Thunderbolt 4 and USB‑A, but no Ethernet is a miss for a business laptop.

Serviceability & Upgradeability – Very Limited

Bottom cover: 8× Phillips screws + clips – easy to remove. Upgrades limited to SSD and 4G card.

ComponentReplaceable?DifficultyNotes
SSD✅ YesLowM.2 2280 PCIe4 – replaceable
RAM❌ NoSoldered LPDDR5-7500 – choose at purchase
Wi‑Fi module❌ NoSoldered – not replaceable
Battery⚠️ LimitedMedium55 Wh – internal, replaceable with care
Keyboard❌ NoNot user‑replaceable – unlike ThinkPads
Display❌ NoHighIntegrated into lid
CPU / GPU❌ NoSoldered BGA
Very limited upgradeability – RAM and Wi‑Fi are soldered, keyboard is not user‑repairable. Competitors offer much better upgradeability.

Storage (SSD) – Fast (Throttles Under Load)

  • Tested Drive: Micron 2500 1TB MTFDKBA1T0QGN – 1 TB, M.2 2280 PCIe4
  • Sequential read: ~5,203 MB/s · write: ~2,991 MB/s – decent
  • Throttles under sustained load – drops from ~7,000 MB/s
  • Single M.2 slot – no expansion
The SSD is fast in bursts but throttles under sustained load.

Memory (RAM) – Soldered

  • Configuration: 32 GB LPDDR5‑7500 (soldered)
  • No SO‑DIMM slots – completely non‑upgradeable
  • Disappointing – competitors offer upgradeable RAM
  • Choose 32 GB at purchase – no aftermarket changes possible
RAM is soldereda major drawback compared to ThinkPads and EliteBooks.

Processor (CPU) – Below Average for This Chip

  • Model: AMD Ryzen AI 7 PRO 350 (Krackan Point, Zen 5, 4 nm)
  • Cores: 8c/16t (4× Zen 5 @ 5.0 GHz, 4× Zen 5c @ 3.5 GHz)
  • TDP: 35 W PL2, 25 W PL1 (sustained)
  • Cinebench R23 Multi: ~12,684 pts – solid
  • ~16% slower than Lenovo ThinkPad L14 Gen 6 with same chip
  • ~15% drop on battery
  • Stable performance under load
The Ryzen AI 7 PRO 350 is below average for this chipcompetitors get more performance from the same CPU.

Graphics (GPU) – Radeon 860M – Fine for Office

  • Model: AMD Radeon 860M (integrated)
  • 3DMark Time Spy: ~2,593 pts – modest
  • Not suitable for gaming – Cyberpunk 2077 FHD Ultra: ~16.8 fps
  • Fine for office productivity
  • Intel Lunar Lake has better graphics
The Radeon 860M is not suitable for gamingfine for office work.

Battery – Slightly Below Average

  • Capacity: 55 Wh – small
  • WiFi surfing (150 nits): ~11.8 hours – below average
  • Competitors manage 14+ hours
  • Internal battery – replaceable with moderate effort
Battery life is below average at ~11.8 hourscompetitors offer longer runtimes.

Chassis & Build – Aluminium + Plastic

  • Materials: Aluminium palmrest and lid + plastic bottom
  • Weight: 1.582 kg (3.49 lbs) – reasonable
  • Dimensions: 313.5 × 224 × 22 mm – thicker than competitors
  • Good build quality – high stability in aluminium areas
  • Plastic bottom is less robust
  • Cannot open with one hand
The chassis is well‑built, but thicker and heavier than some competitors.

Pro tip for resellers: The Dell Pro 14 Plus PB14255 is a hard sellhighlight the build quality and quiet operation, but warn customers about the poor display and soldered RAM.
The display is the biggest weaknessalways upsell the 100% sRGB Low Power panel.
RAM is soldered – competitors offer upgradeable RAM.
The touchpad has delay issues – recommend an external mouse.
The fan is very quiet – highlight for office use.
Consider the Lenovo ThinkPad L14 Gen 6 instead – better performance, better screen, upgradeable RAM.
