Here are laptop specs explained the quick way: the specs that matter most are the processor generation, the amount of RAM and whether storage is an SSD. Get those three right for your use and the rest (screen, battery, ports) is about comfort.
How to read a spec sheet
Kenyan shop listings and WhatsApp catalogues usually read like this:
“HP EliteBook 840 G5, Core i5 8th Gen, 8GB, 256GB SSD, 14″ FHD”
| Part | What it means |
|---|---|
| HP EliteBook 840 G5 | Brand, business range, model and its generation (G5) |
| Core i5 8th Gen | Mid-range Intel processor, 8th generation |
| 8GB | RAM: how many apps run smoothly at once |
| 256GB SSD | Fast storage, 256 GB space |
| 14″ FHD | 14-inch screen, Full HD (1920 × 1080) |
Processor: brand, tier and generation
The tier (i3, i5, i7 or Ryzen 3, 5, 7) tells you the class; the generation tells you how modern it is, and often matters more. A newer i3 can match an old i5. Tier details: what i3, i5 and i7 mean.
Read the model number: – i5-8350U: the first digit after the dash (8) is the generation. – i5-10210U / i5-1135G7: two digits (10, 11) for 10th gen and newer. – Ryzen 5 5500U: the first digit (5) is the series; higher is newer. – The letter matters: U = power-saving (good battery), H/HX = high performance (heavier, shorter battery).
Aim for Intel 8th gen or newer, or Ryzen 2000 series or newer: that is roughly the cut-off for Windows 11 support. To find out what you have: check your processor generation.
RAM: how much is enough
- 4 GB: struggles with Windows 11 and a browser; avoid.
- 8 GB: fine for school, office work and streaming.
- 16 GB: coding, design, heavy multitasking, light video editing.
Check if RAM can be added later (some thin laptops have it soldered). More in how much RAM do I need.
Storage: SSD vs HDD and size
An SSD is the single biggest speed upgrade: a laptop boots in seconds instead of minutes. Avoid HDD-only laptops for Windows. 256 GB is fine if you use cloud storage; 512 GB is more comfortable. See SSD vs HDD.
Screen, battery and ports
- Screen: FHD (1920 × 1080) is sharp; HD (1366 × 768) looks grainy on 14–15″. IPS panels have better colours and viewing angles than TN.
- Battery: on ex-UK laptops, ask for the battery health report; older batteries may last only 1–2 hours.
- Ports: USB-A for flash disks, HDMI for projectors and TVs, USB-C (charging and display on many newer models), and an SD card slot if you shoot photos.
- Keyboard: backlit keys help during evening power cuts.
Spec targets by use
| Use | Processor | RAM | Storage |
|---|---|---|---|
| School, browsing, office | i3/i5 8th gen+ or Ryzen 3/5 | 8 GB | 256 GB SSD |
| Business, heavy multitasking | i5 10th gen+ or Ryzen 5 | 8–16 GB | 512 GB SSD |
| Coding, design | i5/i7 11th gen+ or Ryzen 5/7 | 16 GB | 512 GB SSD |
| Video editing, gaming | H-series i7 or Ryzen 7 + dedicated graphics | 16 GB+ | 1 TB SSD |
Quick answers
A processor from Intel 8th gen or Ryzen 2000 onwards, at least 8 GB RAM and an SSD. Then choose screen size, battery and ports to suit how you work.
A mid-range 8th-generation Intel processor, 8 GB of RAM and a 256 GB SSD: a solid everyday laptop.
An SSD and enough RAM make the biggest difference you’ll feel daily, followed by processor generation.
