ASUS L510 15.6-Inch Laptop (L510MA-DS04): Celeron N4020, 4GB, 128GB

The ASUS L510 (L510MA-DS04) is a thin 15.6-inch laptop built around an Intel Celeron N4020 processor, 4GB of RAM and 128GB of flash storage. This unit is listed as renewed, which means a pre-owned or refurbished product that has been inspected and tested. It runs Windows 10 Home in S mode and comes in black.

Processor and memory

The Celeron N4020 is a low-power chip with a 4MB cache and a boost speed of up to 2.8 GHz, according to the listing. Chips in this class are designed for efficiency rather than speed, and typically handle web browsing, email, documents, video streaming and video calls. Heavy tasks such as video editing or demanding games are outside what to expect. The 4GB of DDR4 RAM works for light multitasking; many tabs and large files can slow it.

Storage

The 128GB is eMMC flash, which is soldered to the board and generally slower than the SSDs in higher-end laptops, though quicker than a mechanical drive. It leaves room for Windows, apps and documents. A microSD slot allows extra storage for files.

Display and size

The 15.6-inch screen has Full HD (1920 x 1080) resolution. The body measures 14.2 x 9.3 x 0.7 inches (about 36 x 24 x 1.8 cm) and weighs 3.6 lb (about 1.6 kg) with the battery. That is slim for its screen size, and easy to carry in a bag.

Windows 10 in S mode

S mode is a locked-down version of Windows that runs only apps from Microsoft's own app library. ASUS says apps there are verified and tested for quality. If you need software from elsewhere, you can switch out of S mode for free, and the listing says it is fast. The switch is generally one-way, so decide first. A one-year Microsoft 365 Personal subscription is included, according to the listing.

Ports and wireless

• USB 3.2 Type-C (Gen1)
• USB 3.2 Type-A (Gen1)
• HDMI
• microSD card reader
• Wi-Fi 5 (802.11ac), which ASUS says is up to three times faster than 802.11n

ASUS notes that USB transfer speed may vary.

Renewed condition

The product is described as professionally inspected and tested to work and look like new. Condition, accessories and warranty terms vary with refurbished items, so look at the terms for this particular unit.

Who it suits

It suits students, home users and anyone who needs a light laptop for browsing, streaming and office tasks.

What to check before you buy

• Your workload: make sure the processor and 4GB of RAM suit your software.
• S mode: confirm that the apps you need are in Microsoft's app library, or plan to switch.
• Storage: 128GB fills quickly with large files, so consider cloud or microSD storage.
• Condition and returns: check the renewed terms, what is in the box and the warranty.
