Lenovo B590 laptop: full specifications and expert analysis

Lenovo B590 is a budget laptop released in 2013, which still remains relevant for office tasks, studying and watching multimedia. This model has become popular due to its balanced characteristics, reliable assembly and affordable price on the secondary market. In the article we will analyze all key parameters devices: from processor and RAM to screen features and battery life, and we will also give recommendations for upgrade and operation.

Despite his age, B590 competes with modern budget laptops in the segment up to 15,000 rubles. Its main advantages are maintainability, the ability to replace components and support Windows 10/11 (with reservations). However, the model also has weaknesses that are important to know about before purchasing. Next is a detailed analysis.

Processor and performance: what can the 3rd generation Intel Core i3/i5 do?

With my heart Lenovo B590 are processors Intel Core 3rd generation (Ivy Bridge), released in 2012. Basic modifications were equipped Core i3-3110M (2 cores/4 threads, 2.4 GHz), and top ones - Core i5-3230M (2 cores/4 threads, 2.6–3.2 GHz in turbo mode). These chips are built on 22nm technical process and support AVX instructions, which is important for compatibility with modern software.

By performance B590 comparable to office laptops 2018–2020. on Celeron/Pentium Gold:

- B browser (Chrome, Firefox) comfortably opens up to 15–20 tabs without stuttering.

- Office tasks (Word, Excel, PowerPoint) are executed instantly, even with large files.

- Multimedia: Video playback 1080p (including YouTube) no problem, but 4K may slow down.

- Light games: CS:GO (at minimum settings), Minecraft, Dota 2 (with FPS drops).

• ⚡ Pros of the processor: low power consumption (TDP 35 W), good overclocking in turbo mode, virtualization support (VT-x).
• ⚠️ Cons: no hardware support AVX2 (problems with new versions of Photoshop, Premiere), weak integrated graphics (Intel HD 4000).
• 🔧 Upgrade: You can replace the processor with i7-3632QM (4 cores), but requires checking compatibility with the motherboard.

⚠️ Attention: When installing Windows 11 on B590 TPM 2.0 checks may need to be bypassed through the registry. Productivity in Win11 10–15% lower compared to Win10 due to lack of optimization for older processors.

RAM and storage: how much can a laptop handle?

Lenovo B590 supports up to 16 GB DDR3-1600 (two slots SO-DIMM). Often found in the basic configuration 4 GB, which is enough for the office, but not enough for multitasking. The best option is 8 GB (2 sticks of 4 GB in dual-channel mode). Important: laptop does not support DDR3L (low voltage memory), standard only DDR3 1.5V.

The situation with storage devices is flexible:

- HDD: standard 2.5" SATA II/III (up to 1 TB in the basic version). Can be replaced with SSD to speed up system boot.

- SSD: supported mSATA (via a separate slot) and M.2 SATA (in some modifications). Maximum speed - up to 550 MB/s (interface limitation SATA III).

- Optane: Not supported due to lack of a corresponding controller.

Screen and graphics subsystem: is it suitable for working with graphics?

Lenovo B590 equipped 15.6-inch display with permission 1366×768 (HD) and matrix TN. This is a typical budget screen from the early 2010s with narrow viewing angles (up to 90° vertically) and average color rendering (coverage sRGB ~60%). Brightness is 200–250 cd/m², which is not enough to work in the sun.

The graphics subsystem is presented integrated Intel HD 4000 (in models with Core i3/i5) or discrete NVIDIA GeForce GT 720M (1 GB DDR3, in top versions). The latter is weaker than modern ones MX250, but will cope with:

- Editing photos in Photoshop (without heavy filters).

- Video editing in Sony Vegas (projects 1080p with simple effects).

- Old games: GTA IV (medium settings), The Sims 3, World of Tanks.

• 🎨 For designers: matrix TN not suitable for professional color work. It's better to connect an external monitor with IPS and coating sRGB 95%+.
• 🎮 For gamers: GT 720M weaker GTX 1050 5–6 times. Modern games (even at minimum settings) will not launch.
• 🔍 Screen problems: found in some specimens "dead pixels" and yellowish backlight (defect CCFL- lamps in early batches).

Autonomy and battery: how long will it last without an outlet?

The laptop comes with 6 cell battery capacity 48 Wh (in some modifications - 62 Wh). In practice, the operating time depends on the load:

- Office mode (Word, browser): 3.5–4.5 hours.

- Video (YouTube, films): 2.5–3 hours.

- Gaming/Rendering: 1–1.5 hours.

After 10 years of operation, the original batteries lose up to 50–70% containers. Replacement with a new one (for example, Camelion BAT-LEN-B590) will cost 2000–3000 rubles. An alternative is to use external battery (power bank) with output 19V/3.42A.

⚠️ AttentionNote: When replacing the battery, check the production date on the label. Batteries older than 2020 may be "relabeled" (with a fake date) and will quickly fail. The best option is batteries with a date no older than 1 year.

Ports, communications and peripherals: what can you connect?

Lenovo B590 equipped with a standard set of ports for its time, but without modern interfaces like USB-C or Thunderbolt. On the left are:

- VGA (for connecting to older projectors).

- HDMI 1.4 (maximum resolution 1920×1080@60Hz).

- 2×USB 2.0 (speed up to 480 Mbit/s).

- RJ-45 (Gigabit Ethernet).

Right:

- 2×USB 3.0 (blue ports, speed up to 5 Gbps).

- Combo audio jack (microphone/headphones).

- DVD-RW drive (in most modifications).

• 🔌 Wi-Fi: module Intel Centrino Wireless-N 2230 (supports 802.11n, speed up to 300 Mbit/s). Can be replaced with Intel 7260AC for support Wi-Fi 5 (802.11ac).
• 🖱️ Keyboard: island type, with separate digital keypad. There is no backlight. Touchpad supports gestures Windows 8/10 (scrolling, zooming).
• 🔊 Audio: speakers Dolby Advanced Audio (2×1.5 W). The sound is hoarse at maximum volume; it is better to use headphones for music.

Cooling and noise: does the laptop get hot?

Cooling system in B590 consists of one fan and two copper heat pipes. In normal mode (office, web), the processor temperature remains at 45–55°C. Under load (games, rendering) can rise to 85–90°C, which is close to the critical threshold (100°C).

To avoid overheating:

- Once every 6 months, clean the fan and radiator from dust (you can use compressed air).

- Replace the thermal paste with Arctic MX-4 or Noctua NT-H1 (the original one goes up after 2-3 years).

- Use cooling stand (For example, Cooler Master NotePal X3).

⚠️ Attention: If your laptop suddenly shuts down under load, check not only the temperature, but also condition of capacitors on the motherboard. B B590 Capacitors near the processor often “swell” (especially in 2013 batches).

Comparison with peers: is it worth buying in 2026?

On the secondary market Lenovo B590 competes with such models as:

- HP ProBook 450 G1 (similar processor, but better screen IPS).

- Dell Latitude E6430 (more durable body, but heavier).

- Acer Aspire E1-571 (weaker cooling, but cheaper).

Benefits B590 before competitors:

- Light weight (2.3 kg against 2.5–2.7 kg at analogues).

- Comfortable keyboard (better than HP ProBook).

- Easy to upgrade (access to RAM and HDD without disassembling the case).

Disadvantages:

- Weak screen compared to Dell Latitude (there often IPS).

- No USB-C And DisplayPort.

- Plastic case less durable than ThinkPad.
