X1 Carbon - Super Slow - Looking for an upgrade

2017-06-12, 19:26 PM

Hey everyone,

 

I bought an almost new second hand 2nd gen X1 carbon a few mths back.  I absolutely love the laptop, been looking for something slim, sleek and powerful, but I'm having some serious performance related problems with it.  I usually have a lot going on, many browser windows, excel sheets, work docs, outlook, pdfs, skype, photoshop, AVG AV, etc all running for my work simultaneously and the laptop just can't keep up.  It's extremely slugish, slow and freezes constantly.  My CPU, Memory and Disk is always maxed out when I check task manager (90-100%).

 

My currently machine has 4GB ram (mistake #1) and equipped with the i5-4300U CPU (1.90GHz 2.49GHz).

 

I'm trying to find a replacement, but I don't want to spend over 2K on a new laptop.  I'm trying to find some used Gen 4s for sale.  I believe a Gen 3 might also give me some issues.  I found a good deal on the below:

 

X1 - 4th Gen Intel Core i7-4600U processor. 3.3 GHz Turbo Boost
-Intel HD 4400 Graphics
-Windows 10 Professional 64-bit
-8GB DDR3 Memory
-256GB Premium SSD Storage
-14.0" 1600x900p display

 

I tried looking this up on the Lenovo site and I don't see this CPU offered on the 4th gen.  Is this a false advertisement ad or is it an actual Gen 4?

 

Any suggestions on the above, or the Gen 3s? Is their any other Lenovos which are also slim and powerful which can handle my workload and is suggested?

 

Thanks!

Dan

Hi dannyddn1, and welcome to the Lenovo User Community!

 

Well that's confusing isn't it.

 

Lenovo has ThinkPad X1 Carbons, Gen 1 through Gen 5.

 

Then there are Intel Core processors, 1st Gen through 7th Gen.

 

X1 Carbon Gen 5 can be configured with either 6th gen or 7th Gen Core processors.

X1 Carbon Gen 4 is configured with 6th Gen Core processors.

X1 Carbon Gen 3 is configured with 5th Gen Core processors.

X1 Carbon Gen 2 is configured with 4th Gen Core processors.
X1 Carbon Gen 1 is configured with 3rd Gen Core processors.

 

Got it?

 

The ad you are looking at is for a ThinkPad with an actual 4th Gen Intel Core processor. But it's a Lenovo X1 Carbon Gen 2.

 

Wow, who dreams this stuff up :smileyvery-happy:?

USB-C: Just cos it fits don't mean it works.
I don't work for Lenovo. I'm a crazy volunteer!

Hi there,

 

Appreciate the response! Got it! I thought the X1 Carbon Gens and Processors would align but I guess not, thanks for clearing the confusion for me! :)

I almost worry that 8GB of RAM isn't going to be sufficient for you. You definitely need an SSD. I think that a T4x0s with 12GB of RAM or more might be a better option.
I really think that a T4x0p is your best option, but it won't be super slim. The p series support processors with 4 actual cores, and if you are multitasking that much 4 cores can be benfical. It is going to be up to you to determine the sweet spot when it comes to portability, price, and power of the machine.

If your CPU is literally sitting maxed at 100% even when the system should be near idle then you might have some software issues.

If your memory is always full, then this will cause the disk to be always active (causes extra system sluggishness if you have an HDD) due to excessive paging. This probably means 8GB of RAM isn't enough for your workflow.

Hi there, appreciate the response.  I actually use a T440 for work but I don't have so many things running on it, but it performs well overall.  I've always wanted something slimmer than the T440, which is why I bought the X1 carbon, I absolutely love the design and aesthetics. 

 

I will definitely look in to your suggestions.  As I'm typing this, I have a youtube video on the  background listening to a keynote speech and it freezes every 10-20 seconds.  I  have my task manager up and my disk is constantly in the red (96-99%) and my memory and cpu is going bonkers, up and down, eventually all 3 hit 99% (CPU, Memory, Disk), the performance is just terrible!

At idle, the levels are fine.  It's when I perform any tasks, could be opening new applications or playing audio/video, or opening additional web browser tabs, it spikes.  I always have my adobve reader, outlook, word, excel open with multiple documents and multiple tabs open in chrome.  I'm always viewing open documents and links throughout the day, it would be a real pain to close them and look for all the files every time I need to view something or edit a document.

Seems odd. I'm working on my 3rd gen X1 right now. I currently have both Firefox & Chrome up, about 40 tabs between the two. I have a video going in the background. I'm at around ~50% CPU, under 20% Disk, and 90% Memory.
Is there a particular program that is hitting the disk so much or is most of the disk activity swapping? If it is just the swapping, then it really could just be that it is mostly a memory issue. I've always been a memory intensive user. I've had 8GB or more in every primary machine I've owned since the T400 days. My older portable machine is a Twist with only 4GB of memory. I do make sure to avoid hitting the wall where it has to swap too much.

Do you have a conventional spinning hard drive rather than an SSD in it?

I don't think any of the X1 Carbons support spinning rust. They don't have the internal space.
My Twist has a 3317U (I think), 4GB of RAM, and a Samsung 850 EVO 500GB. It is the RAM that holds it back. The T420 that I had prior to it with 8GB of RAM and a slower SSD would run circles around the Twist despite an older processor.
