Pro's and Con's

"The Lenovo ThinkBook 15 Gen 4 Intel (15") is a solid choice for business users who need a reliable and secure laptop for everyday tasks. The 12th Gen Intel Core processor provides good performance, and the FHD display is clear and bright. The laptop is also durable and well-built, with a variety of ports for connecting peripherals. However, the battery life could be better, and the weight is a bit on the heavy side. Additionally, the RAM is soldered on most models, so you won't be able to upgrade it later."

Good laptop for home or office.

Solid choice for a business-grade laptop. I'm not a huge fan of 15" screens, but this is what was provided. We have purchased several of these with no complaints.

Responsive upgrade for business tasks

Upgraded from a prior gen think pad. The main con of my prior gen laptop was it didn't handle well dual 4k external monitors and one day it just stopped booting. This one feels more responsive.

Fit my needs

I purchased a Lenovo because that was the brand my employer got me set up for work from home with. I liked that work computer and got used to it so decided to go with Lenovo for my personal computer as well. I'm not real tech savvy but this was plug and play which went well for me. I'm sure I'm not using it to its full capacity but IF I decide to utilize all the bells and whistles they will be there. I have every confidence it will last me for years.

Best BIOS

Better than HP or DELL. BIOS is more user friendly and price is better for the same processor.

Great Laptop

I needed a new laptop. I wanted one with a 15.6 inch touch screen, lighted keyboard, numeric keypad, an SD card reader and a 512gb SSD with a few other requirements. I searched all the major brands and couldn't get all the bells and whistles I wanted, until I landed on Lenovo's website. This laptop is more than I'll ever need since I'm retired, but since it was on closeout and had everything I wanted, I bought it. It's not old stock either since it's manufacture date was only a few months before my purchase. Since receiving it, I've not been disappointed. It was easy to set up and is faster than I will ever be. The build quality feels really good and everything works. That's all I ask for.

My Lenovo

Me gusta mucho esta computadora. Su pantalla táctil funciona muy bien Tomando en cuenta que su procesador no es el más actualizado Pero es para uso en high school. Su especificaciones son suficientes

Good but not excellent

Lenovo ThinkBook was delivered promptly, impressed by its neat monitor, and also as it was easy to carry. However, within one month the rubber pad at the back of the laptop loosened and came off. Also, the HDMI port was not working. I was within the 3-year repair scheme, so I availed it and they changed the motherboard with scratch prevent pad and the port too. Overall it was not the best value for money with the scheme as it was not totally hassle-free though the service was prompt and good.

I guess I expected more for the price

Bought this laptop a month ago. For the most part I'm pleased with it, except: the volume doesn't get that loud, when on a Zoom call I have the volume on 100%. Battery life is not as long as it says, lasts maybe 3 hours. And runs hot.

Practical everyday computer

It has a keyboard with the convenient 10-key on the side. They board is back-lit and it has a touch-screen. So far, speed seems up to expectations -- in fact a little faster than I expected. This is my first SSD, I like that.

The system was fine. Startup and was frustrating.

Once I got the software loaded, the computer has been fine. HOWEVER, the instructions that were sent did not match the operating system, and customer support could not help me. It should have been a simple change in the instructions sent: the computer was loaded with a Windows 11 Pro operating system, not Windows 10, but the instructions for loading Microsoft 365 were for Windows 10. If installation instructions for Microsoft 365 had been adjusted to match what was installed (Windows 11 Pro), there wouldn't have been a problem. 2nd issue, using consistent wording with Adobe product code versus product key. Small corrections would have made the process very smooth. As it was, after talking to Lenovo and having to go through Microsoft chat (bots) before speaking to an actual human, I very nearly sent everything back. The Adobe issue was relatively easy to solve, but I still had to call Adobe support, only to find out the CODE meant KEY.

Great overall laptop. Powerful enough to get work done but not big and bulky. Lots of great features, fingerprint, usb-C ports, win11. It's 15" but light and compact where I feel comfortable taking it on the go.
