@AudriusM The laptop uses USB-C to charge. You just need a charger that works in your country Voltage / Hz, the laptop doesn't matter.

@Kit21

DDR4 is not available in a low-voltage (DDR4L) yet, normal DDR4 is bigger and uses more power, and DDR3L uses a lot more power and is slower than LPDDR3. Meaning LPDDR3 was pretty much the only option left. Also, running at 2133MHz with lower CAS latencies, the RAM in the current macbook pro’s scores on par if not better than budget DDR4 in most laptops.

 

Lenovo could have gone for DDR4–2400, but that generally uses 1.4V instead of ~1.2V,meaning the RAM uses close to 20% more power, takes more area on the logic board (meaning a thicker laptop or smaller battery) and the CAS latencies are usually worse on DDR4, meaning actual gains are minimal at best. The only real drawback of using LPDDR3 is the limitation of 16GB, which again is an intel issue.

 

Quoted from https://www.quora.com/Why-is-Apple-still-using-LP-DDR3-in-their-MacBooks-instead-of-LP-DDR4 as they wrote it well.

"Could you check what is the Input voltage ? I am interesting if it can be used both, in Europe and USA."

 

...

Below is the AC adapter that came with my pre-production sample. It has the standard, wide range of input voltage. Most likely all you'll need is the proper plug adapter to fit the wall socket.

 

Hope this helps.

Thanks for the first impressions. The machine looks gorgeous. The speaker improvement is most welcome. How does tablet mode feel now that Lenovo did away with the lift-and-lock mechanism?

 

My thoughts without having touched one, I hope Lenovo brings back the volume rocker. When in stand mode we need an easy way to change the volume, and the Win10 UI is not very convenient. 

 

Also: where are the 3:2 or 4:3 aspect ratio screens? Why waste all that lower bezel space when it could be filled with beatiful and functional pixels!

 

And it has to be said, the removal of the microSD card slot is annoying. How much is a combi SIM/uSD slot? 15 cents? Please add that back as well.

 

And finally my long running pet peeve, I want these machines to approach 2.5lbs, if physics allows it! Otherwise these machines are really converging on perfection.

Since this was added to PSREF yesterday I did a compare with Gen 3. Two things that I noticed that I thought were interesting. FHD screen is now brighter but glossy instead of anti-glare. Not sure I like that change. Also the battery is smaller, which isn't great either. I am getting Gen 4 since 3 is already 16 months into support life cycle but wish those changes hadn't happend. Also why is this posted in Community SPotlight making it harder to find as opposed to X1C7 in X1 group? Oh and why can't I get IR camera except on highest end model in US but in other countries you can get it on lower speced machines?

Are the screws on the service panel captive? The service manual doesn't say that they are, but the service manual for the 3rd gen didn't say that those screws were captive either.

...

Pretty sure the base cover screws are captive, but I've not pulled my cover off to check. Note in the HMM that when screws are *not* captive, there's a table listing screw size and number of each.

 

Example: page 73 of https://download.lenovo.com/pccbbs/mobiles_pdf/tp_x1_carbon-yoga_hmm_en.pdf showing removal of the SSD. Non-captive screw.

 

Regards.
