Takes a beating but it's slow.
This tablet is very sturdy and mostly functions well. The price is very reasonable, but the device is just so slow. Even booting up takes a long time, and playing little kid games or light web browsing really bogs it down. Some kid games will load sometimes and not others. By modern standards, this is almost unusable at times, just because of the lack of horsepower.

Superb laptop
My 4X21M37465 laptop has been outstanding. I've had around 10-12 hours of battery life with great application responsiveness. I've had great experiences with the Lenovo support who have been very helpful.

Exactly as described
The computer charger charges my Lenovo Yoga. My other one was worn down from 2 year of use though Nursing School. I have no complaints. The wall and adapter were both included.

Ordering, good. UPS signature only delivery, bad!
The process of ordering the computer was great, however getting it delivered by UPS by signature required only was a nightmare. There is no way to change it and sign it electronically if you can't be there when they're going to deliver. Also UPS gives you a date they're going to deliver in time but then they never do it at that time and therefore if you take the day off or have any other plans you could miss them. I miss them twice and I purposely took time off to be there when it said to be there. The computer itself was bigger than I wanted and they told me that they discontinued the 15-in size, but I'm hoping to get used to it. The 14 inch size would have been way too small for work.

Simply works as OEM replacement power supply.
This is a second power supply for work computer. Simply works which as it should with power supply bricks for laptops. No worries about incompatibility with a Lenovo laptop.

Thinkpad Is A Great Machine.
After 1 week of constant use:
1. Great hardware. Very fast. Very quiet as I have yet to hear the fans. Fans seem to work more than I expected, but I only notice them as I feel the side vent air.
2. Not very much bloatware.
3. OLED screen is outstanding, but so was my 11 year old LCD. Not sure it is worth the $$$.
4. Keypresses are a longer stroke than I expected, but keyboard is definitely crisp.
5. First time with the Trackpoint, and I like it very much.

Perfect
I love Lenovo products. It was very easy to find the correct charging cable for my daughter's laptop, and shipping was fast.

While the original is now out of stock, this replacement works perfectly. This is a suitable substitute.

Lapop suffers from Windows 11 issues
Not necessarily Lenovo's fault, but Windows 11 had to be reinstalled, along with all my apps and software. There were also connection issues with the Lenovo dock.

Works perfect with Slim Travel Dock
I bought this to use with my new Slim Travel Dock to power my Thinkpad. This 100 watt power adapter connected to the Travel Dock passes the required 65 watts to my Thinkpad. Now I only have one cable connected to my Thinkpad and all other connections are made on the Slim Travel Dock. Makes it easy to quickly disconnect my Thinkpad.

Quality charger
Excellent charger, what can I say? Paired with my Thinkpad (which has a 75 Wh battery), makes for a good experience and very fast charging (plus it works for other devices in a pinch!). Delivery was also quite fast. Definitely worth it!
