A notable aspect of this model is the Linux operating system, which distinguishes it from other versions of the C15M sold with Windows. Therefore, it is crucial to check the exact product code before purchase if the user prefers a more familiar operating system. The main panel measures 15.6 inches, has Full HD resolution and IPS technology, with an anti-reflective finish. Although the size provides a vast workspace for spreadsheets and documents, it operates at a 60 Hz refresh rate and includes integrated Minitela.

Positivo Vision i15M

The Vision i15M can be classified as an intermediate specification notebook because it offers the Intel Core 3 N300 processor, 16 GB of RAM, and a 256 GB SSD in M.2 NVMe format. The 16 GB of memory allows keeping several applications and tabs open, and the SSD ensures faster storage compared to the eMMC of entry-level models.

The processor is the Intel Celeron N4500, with two cores, and it comes with 4 GB of RAM and integrated Intel graphics. This configuration is suitable for light activities, although the amount of RAM limits multitasking capability.

Storage is 128 GB in eMMC, a different solution from the M.2 SSDs present in newer Vision models, and does not offer the same expansion ease. The Duo C4128E weighs approximately 1.1 kg, has an HD resolution screen, and comes with Windows 11 Home.

Positivo Vision R15M: The best cost-benefit

In summary, the Positivo Vision R15M stands out as the option most geared towards multitasking and represents the best value notebook from the brand.

Furthermore, the SSD can be expanded if necessary.

Positivo Duo C4128E: Focus on portability

The Positivo Duo C4128E is the brand's 2-in-1 model. Its 11.6-inch touchscreen can rotate 360 degrees, allowing use in various positions, including with the screen folded back. This model is also designed for basic tasks and prioritizes portability, weighing about 1.1 kg.

It is possible to opt for an economical model from the brand if the focus is on acquiring a device for studies, internet browsing, video conferencing, and simple daily tasks. Positivo offers notebooks in this range of up to R$ 2,000 in Brazil, providing more modest hardware configurations. However, it is essential to conduct a meticulous comparison between the amount of RAM, the type of storage, and the operating system with competitors in the same price range. The final decision must always be based on the specific technical sheet of each model, and not just on the brand's reputation.

The Lenovo notebook catalog for 2026 ranges from basic models, suitable for studies and less demanding personal activities, to high-performance laptops equipped with powerful processors, more RAM, and dedicated graphics cards, ideal for both gamers and professionals with intensive work demands.

However, there are models capable of meeting needs such as web browsing, streaming content consumption, and document reading at a more affordable price.

Tecnoblog compiled a list with five options from brands such as Asus, Lenovo, Samsung, and Positivo, detailing the pros and cons of each to aid in choosing the ideal device for daily use.

Lenovo IdeaPad Slim 3i (83L7002FUS)

This model represents the lowest-cost notebook with the best performance listed. It is equipped with the Intel N150 processor (with a maximum clock speed of 3.6 GHz and manufactured on 10 nm), 8 GB of RAM, and 128 GB of storage in UFS 2.2 format. It is recommended for basic productivity tasks, such as text editing, viewing PDFs, browsing, and video playback, without experiencing slowdowns.

The device has a webcam that supports 720p video conferencing and recording. Below the camera, there is a 15.6-inch LCD screen with Full HD resolution and a brightness peak of 250 nits. Additionally, it features a 47W battery, which guarantees up to 12 hours of video playback (in a local environment), and weighs about 1.55 kg.

The ASUS VivoBook Go 15 (E510KA-BR1375WS) is an entry-level notebook designed for daily use, prioritizing portability and operating completely silently thanks to its fanless cooling system. Its 15.6-inch LED screen offers good visibility for spreadsheets and documents, featuring anti-glare technology and HD resolution (1366 x 768 pixels).

Although available in configurations with 8 GB of RAM, in this price range it uses an older and less efficient processor, the Intel Celeron N4500 (2 cores, ranging from 1.1 GHz to 2.8 GHz). Combined with 128 GB of eMMC storage, this processor can create bottlenecks in situations of intense multitasking, complex spreadsheets, or browsing with multiple open tabs. A favorable aspect is the presence of an M.2 slot for SSD expansion. Its weight is approximately 1.57 kg.

Positivo Vision C15M (C4128B-15)

For those seeking an even more economical alternative, especially for studying and reading, the Positivo Vision C15M is an option. This model, also in the R$ 2,000 range, incorporates the Intel Celeron N4500 processor (up to 2.8 GHz on 10 nm) and 128 GB of storage (eMMC), but is limited to only 4 GB of RAM, restricting its performance to basic uses.

The main LCD screen measures 15.6 inches and has Full HD resolution. It includes a simple HD webcam with a light bar adjustment. Additionally, it has a 1.54-inch mini-screen used to display WhatsApp notifications, device status, and photos. Weighing 1.7 kg, the device comes with a 5,000 mAh battery, which takes approximately 2.5 hours to fully charge.

Samsung Galaxy Book Go (NP340XLA-K0ABR)

The Samsung Galaxy Book Go comes factory-equipped with the Snapdragon 7c Gen 2 processor (up to 2.5 GHz on 8 nm), 128 GB of memory (eUFS), and only 4 GB of RAM. It is better suited for running cloud-based services and streaming, as it tends to freeze with more demanding applications or during multitasking. Content visibility under sunlight is hindered by the screen's brightness peak of only 220 nits on the 14-inch LED screen. However, the display features anti-reflective technology and Full HD resolution, in addition to integrating a webcam capable of recording in 720p.

The battery is one of the strengths of this equipment, offering up to 18 hours of video playback autonomy. Its lightweight design (1.3 kg) and 180-degree hinge facilitate transport.

Positivo Duo (C4128E)

The Positivo Duo is a 2-in-1 device, functioning as both a notebook and a tablet. Like the others, it uses the Intel Celeron N4500 chip, 4 GB of RAM, and 128 GB of internal memory (eMMC), directing its use primarily toward simple tasks. Its 11.6-inch LCD screen has a resolution of only 1366 x 768 pixels, but it is touch-sensitive and compatible with the included capacitive pen. There is also a built-in 1 MP webcam that records up to 720p.

This notebook is the lightest on the list, weighing 1.1 kg, and has a 360-degree hinge for tablet mode usage. It is also equipped with a 5,000 mAh battery.

Considering that notebooks up to R$ 2,000 generally share similar specifications, it is recommended to compare equivalent models and choose the device that offers the best overall package. It is important to note that the increase in notebook prices is linked to the global memory chip crisis. Manufacturers are prioritizing the production of HBM components (high-bandwidth memory) for AI data centers, which results in the sacrifice of DRAM and NAND chips used in smartphones and notebooks. This reduced supply raises the cost of memory chips, and brands pass this increase on to the end consumer.

Low-cost notebooks are viable for basic uses, such as browsing and web services, provided they fit the buyer's usage profile. For those seeking a lower price, buying a used device can be considered, but one must be aware of the inherent risks. Refurbishment focuses on repairing faults without guaranteeing the integrity of all components before repair, which can result in a device with a reduced lifespan.

In summary, notebooks in the R$ 2,000 range are ideal for basic use and favor those who need software compatible only with Windows/Linux or for long periods of typing. The best tablets in the same price range usually provide a superior experience for video lessons and reading, in addition to being more portable, although accessories like pens and keyboards can increase the total cost.
