It is the most capable laptop at this weight: an AMD Ryzen AI 7 350 with Radeon 860M graphics, 16GB of memory, 512GB of storage and a 57Wh battery, with Windows 11 Pro. It is sold by a reseller, so the base laptop is Lenovo's but the listing is a reseller's.

• 16GB of memory and 512GB of storage, the most stated in this list
• 57Wh battery, tied for the largest stated here
• Windows 11 Pro

Cons

• Reseller listing: confirm new condition and whether Lenovo's warranty applies
• 60Hz screen, per the listing

Good fit if

• Business users and engineers who carry a laptop daily
• Buyers who need Windows 11 Pro on a capable 14-inch machine

Skip if

• You want the maker's own listing without checking a reseller
• You need more than 16GB of memory

Verdict: The clear choice at 1.45 kg for work beyond the basics.

It is the same ThinkPad P14s Gen 6 with the same Ryzen AI 7 350, Radeon 860M graphics and 57Wh battery, from the same reseller. The listing does not state memory or storage, so you would need to confirm both before buying.

Pros

• AMD Ryzen AI 7 350 with Radeon 860M graphics
• 57Wh battery, tied for the largest stated here
• Windows 11 Pro and a 14-inch FHD+ IPS screen, per the listing

Cons

• Memory not stated by the seller
• Storage not stated by the seller
• Reseller listing: confirm condition and warranty

Good fit if

• Buyers who can confirm the configuration with the seller first
• Business users who want the P14s Gen 6 platform

Skip if

• You want a listing that states its full configuration: choose the 16GB and 512GB P14s instead
• You do not want to contact a seller before buying

Verdict: Prefer the 16GB and 512GB listing unless this one states a better configuration.

• Established maker (Acer)

Cons

It is the only 15.6-inch laptop here, with an FHD screen, Windows 11 and 128GB of storage. It uses an Intel Celeron N4020, which Intel lists with 2 cores, 2 threads and a maximum of 8GB of memory, so it suits light tasks only.

Pros

• 15.6-inch FHD screen, per the listing, the largest here

• 128GB of storage

Cons

• Intel Celeron N4020: 2 cores per Intel, launched in 2019

• You want an established maker's support

Verdict: A large screen at this weight, with an entry chip that limits it to light use.

Side by side

How we picked

How we picked: 4 laptops in our catalogue state a weight of 1.45 kg, so every one of them appears here. Two are listings of the Lenovo ThinkPad P14s Gen 6 with an AMD Ryzen AI 7 350, both sold by the same reseller; one states 16GB of memory and 512GB of storage, the other states neither. They are near-duplicates, and the pool has nothing else of that class at this weight, so both stay and we say which to prefer. The other two are an Acer TravelMate B3 11 and a 15.6-inch laptop sold under the brand Unowo. Processor facts come from Intel. Prices on this page are live: each one is read from the store listing and shown with the time it was read. Nobody at wikilaptop.org has tested these units.

How to choose

What 1.45 kg means to carry

At 1.45 kg a laptop is portable enough for daily use and comfortable for most people on a commute. Add the charger when comparing total carry weight.

This weight covers a wide range of machines: in this list, a 14-inch business workstation, an 11.6-inch classroom-size laptop and a 15.6-inch basic model all state 1.45 kg. So weight is only the starting filter; the processor, memory and screen tell you more.

Processor: current chip or entry chip

The two ThinkPads use the AMD Ryzen AI 7 350 with Radeon 860M graphics, the strongest chip in this list. The Acer uses the Intel N150, which Intel lists with 4 cores and 4 threads, launched in 2025. The Unowo uses the Intel Celeron N4020, which Intel lists with 2 cores and 2 threads, launched in 2019.

The N150 and N4020 are fine for web, email and documents but slow down with heavier work.

Memory and storage

Only one pick states more than 4GB of memory: the ThinkPad P14s Gen 6 with 16GB. The Acer and the Unowo list 4GB, and Intel lists a maximum of 8GB for the N4020. One ThinkPad listing states no memory or storage at all.

Microsoft lists 4GB as the minimum for Windows 11. For Windows 11 with a browser and office apps, 8GB is a comfortable minimum and 16GB leaves room for heavier work.

Screen: size and refresh

Screens here run from 11.6 inches to 15.6 inches. The ThinkPads list a 14-inch FHD+ panel and the Acer an HD panel, all at 60Hz. A 60Hz screen is standard for office work, study and video; higher refresh rates mainly matter for gaming, which none of these laptops is built for.

Resellers and small brands

Both ThinkPads are sold by a reseller, and the 15.6-inch laptop under the brand Unowo. Before buying, confirm whether the unit is new or refurbished, whether the maker's warranty applies, and who provides support. The base laptop of the two ThinkPads is Lenovo's; for the Unowo, check who made the base laptop.

Questions

Is 1.45 kg easy to carry?

Yes. For most people it is comfortable for daily commuting and campus use. Add the charger's weight when comparing total carry weight. At this weight you can find anything from a small 11.6-inch laptop to a 15.6-inch model, so let screen size and performance decide between them.

Is 60Hz enough for a laptop screen?

For office work, browsing, study and video, yes. Higher refresh rates make motion smoother and mainly matter for gaming. The ThinkPads and the Acer in this list state 60Hz, and none of the four is designed as a gaming laptop, so refresh rate is not a deciding factor here.

What matters more than weight at this level?

The processor, memory and storage. The laptops here all state 1.45 kg, but they range from a ThinkPad with an AMD Ryzen AI 7 350 and 16GB of memory to basic machines with 4GB and entry chips. Those differences shape daily use far more than the weight does.

Why are there two listings of the same ThinkPad?

Every laptop in our catalogue that states 1.45 kg appears here, and two of them are listings of the ThinkPad P14s Gen 6 from the same reseller. One states 16GB of memory and 512GB of storage; the other does not state either. Prefer the one with a stated configuration, or confirm the other before buying.

Did you test these laptops?

No. Nobody at wikilaptop.org has used these units. We compared them from the specifications stated on each listing, with processor facts from Intel. We do not describe screens, keyboards or battery life, because those claims need testing we have not done.
