Re: X1C3 dead left side USB

Sorry, I meant to post an update earlier and forgot. I got to thinking after I ordered the replacement USB / audio port board and remembered that as part of an earlier warranty service, Lenovo replaced my motherboard. That made me wonder if anything was amiss on the MB end of the cable that connects...

X1C3 dead left side USB

Just checking to make sure I have not missed anything.... as the title says, my left side USB port is suddenly totally dead. It does not supply power and it does not communicate with externally powered USB devices. I have uninstalled everything under the USB header in device manager and let the OS r...

System Update fails to install WLAN driver

Thinkpad X1C, gen 3, 8GB RAM, 256GB SSD, Win10 15063.540 For some reason, Lenovo System Update repeatedly fails to install the WLAN driver for the Intel AC7265 card. Every time I run System Update, it sees the currently installed version 19.51.0.4, downloads and (it claims) installs version 19.70.0 ...

Re: X1C3 review by former X61S user

But the X61S (even the 1.8GHz model I ended up with) just wasn't QUITE cutting it for streaming videos (95% CPU use on a good day) My x60s (L2400) reports 25% CPU usage while streaming a very busy 720p video. What is the CPU usage while streaming on your x1c3? My X1C3 (i7-5600U 2.6GHz) reports abou...

So far, I have not been able to reproduce the issue either with WiFi connects OR an external RF ...

Re: Power efficiency

Thanks, I figured it was about like that. It also seems to be that having four cores means the system can multi-task more efficiently and maybe spends less CPU cycles switching tasks? At some point I want to compare video render times on my X61s, my 3GHz C2Duo desktop and the i7 X1C3 to see if the X...

Re: X1 Carbon (5th gen, 2017) : 8gb Ram or 16gb Ram , i5 or i7

Can anybody can say something about fan noise on the X1 or T470s ? The 470s should be very noisy too. Is the i5 going to produce less fan noise than the I7 ? I don't know about the Gen5 but the fan in my i7 X1C Gen3 is hands down the quietest laptop fan I have EVER heard. When it runs (which is not...

Re: X1 Carbon (5th gen, 2017) : 8gb Ram or 16gb Ram , i5 or i7

256 GB is too low these days so yes, 512 GB one makes sense. Just FWIW.... I dual boot Windows 10 and Linux on a 256GB hard drive very comfortably. I allocated 100GB for Windows, 50GB for a separate partition for misc. storage (photos, MP3s, etc.) and the rest for Linux and unallocated set-aside. I...

Power efficiency

Just curious here. Cruising the net and checking Email, my old X61s (1.8GHz) runs slightly warm to the touch with the fan running on the very lowest setting. By contrast my new X1C3 with an i7 in it runs dead cold to the touch even playing HD videos and the fan is usually OFF. CPU usage rarely rises...

Re: Windows 10 Creators breaks screen dimming and external displays

FWIW, screen dimming and external display work fine on my X1C3 (WQHD touch display) on Creators. However, it was installed as a clean install, not an upgrade if that makes a difference. I do recall that immediately after installation, screen dimming behaved as you described. But after the system set...

Good idea about trying to resume with the WiFi card disabled (F8 on the X1C).
My X1C1 still has the (standard) F5 for wifi and has no flashing problems (running W7 Pro/64 and Intel 6205N wifi card).
