The 30-Second Version

The Lenovo ThinkBook 14 2-in-1 G4 is a flexible business convertible laptop with a killer feature: a massive 4TB SSD. Its Intel Ultra 7 performance is average, making it great for office work but not for gaming or heavy creative tasks. It's a solid pick for storage-hungry professionals on the move.

Overview

If you're looking for a business laptop that can also work as a tablet, the Lenovo ThinkBook 14 2-in-1 G4 is a solid option. It's a 14-inch convertible with an Intel Ultra 7 155U processor, 16GB of DDR5 RAM, and a massive 4TB NVMe SSD. That's a lot of storage for a machine in this class. It runs Windows 11 Pro and has a touchscreen IPS display, making it a flexible pick for presentations, note-taking, or just getting work done on the go. People often search for 'business 2-in-1 laptop' or 'convertible laptop with good storage,' and this ThinkBook fits that bill.

Performance

The Intel Ultra 7 155U is a capable 12-core chip for everyday business tasks. In our database, its CPU performance lands right in the middle of the pack, which means it's perfectly fine for office apps, video calls, and having dozens of browser tabs open. You won't be setting any speed records, but you also won't be waiting around. The integrated Intel Graphics are about average too, so don't expect to do any serious gaming or video editing. The real standout here is the storage. That 4TB SSD is in the 98th percentile, which is basically best-in-class. You'll have room for everything, and it'll all load fast.

Value & Pricing

Here's the tricky part: the price. Our data shows a wild spread from about $1,000 to over $250,000 across different vendors. That high end is clearly an error or a bizarre listing. At around the $1,000 to $1,500 mark, this ThinkBook makes sense if you really need that 4TB of fast storage. If you don't, you can find similar 2-in-1s from HP or Dell for less. Always check Memory Express and other retailers for the real going rate.

vs Competition

Let's name some names. Compared to an Apple MacBook Pro 14" with an M5 chip, the ThinkBook loses hard on raw CPU and GPU performance, but you gain a touchscreen, a 2-in-1 hinge, and Windows. The ASUS ROG Zephyrus G14 is in another league for gaming and creative work, but it's not a business-focused convertible. A closer match is something like an HP Spectre x360 2-in-1. You'd trade some storage for potentially better build and display quality. The ThinkBook's main play is offering that giant SSD in a familiar business convertible form.

Common Questions

Q: Is the Lenovo ThinkBook 14 2-in-1 good for gaming?

No, it's not. With integrated Intel graphics and a score in the 18th percentile for gaming in our database, it's only suitable for very basic, old games. Look for a laptop with a dedicated GPU if gaming is a priority.

Q: How does the ThinkBook 14 compare to a ThinkPad?

ThinkBooks are generally the more consumer-friendly, value-oriented cousins to the legendary ThinkPad line. This ThinkBook 2-in-1 offers more design flexibility and that huge SSD, while a ThinkPad like the P1 Gen 7 might offer more power or a superior keyboard for a higher price.

Q: Can you use a pen with this 2-in-1 laptop?

Yes, the touchscreen display supports active pen input, making it useful for note-taking, signing documents, or light sketching. You'll likely need to purchase a compatible Lenovo pen separately.

Q: Is 16GB of RAM enough for 2025?

For the business tasks this laptop is designed for—spreadsheets, presentations, web apps, and video calls—16GB of DDR5 RAM is plenty and should keep you running smoothly for years.

Who Should Skip This

Skip this laptop if you're a gamer, a video editor, or a power user who needs the fastest CPU. Its integrated graphics and middle-of-the-pack processor won't keep up. Also, if you live in the cloud and don't need 4TB of local storage, you're paying for space you won't use. In those cases, consider a more powerful clamshell laptop or a 2-in-1 with a better screen and CPU, even if it has less storage.

Verdict

So, should you buy it? If you're a business user who needs a ton of local storage in a portable, flexible package, this ThinkBook 14 2-in-1 is a very sensible choice. It's reliable, has all the right business features, and that 4TB SSD is a genuine luxury. But if your priority is pure processing power, stunning display quality, or gaming, you should look elsewhere. This is a workhorse, not a racehorse.
