The battery life topped 7 hours in our CNET tests, besting the Apple MacBook Pro.Īs you'd expect, the ThinkPad T420's keyboard is very comfortable: it's the Lincoln Town Car of keyboards, or a comfy orthotic shoe. With its slightly faster-than-average Core i5-2520M CPU, the T420 rivaled Core i5 competitors in our benchmark tests, and the included Nvidia graphics are good enough to play a game like Street Fighter IV at medium settings. What you gain here is durability, port selection, and a surprisingly good mix of speed and battery life. Even so, the T420 isn't as hard to heft as you'd expect based on how it looks. The ThinkPad T420 is heavy, at 5.2 pounds for a 14-inch laptop, and its body is nearly 1.2-inch thick. In terms of design, nothing's really changed.

The last time we reviewed a ThinkPad T series was the ThinkPad T410 back in December 2010. Nvidia NVS 4200M / Intel HD 3000 (Optimus) However, we can ding the T420 a little on price: our configuration's priced climbed above $1,000, although the ThinkPad T420 starts as low as $749 on Lenovo's Web site for an entry-level version with a Core i3 processor and fewer bells and whistles. It feels unfair to attack the design of the ThinkPad T420 too much, because it's clearly not meant for the average consumer-this vPro-equipped laptop is all business. And, obviously, there's an optical drive (another feature frequently missing from laptops nowadays). Older ports are also here in force: everything from eSATA to ExpressCard, and even FireWire, is included. You can light your keyboard with a top-mounted LED light next to the Webcam, thank you very much-no backlit keyboard here. Lovers of older laptop tech won't be disappointed: a rubberized trackpoint sits in the middle of a set of thick, tapered keyboard keys, while large extra trackpoint-controlling buttons sit above the touch pad. iwlwifi 0000:02:00.The ThinkPad T420 is the laptop that escaped from your IT department, and might even be sitting on your desk as we speak. ieee80211 phy0: Selected rate control algorithm 'iwl-mvm-rs' iwlwifi 0000:02:00.0: Direct firmware load for iwlwifi-8265-23.ucode failed with error -2 iwlwifi 0000:02:00.0: Direct firmware load for iwlwifi-8265-24.ucode failed with error -2 iwlwifi 0000:02:00.0: Direct firmware load for iwlwifi-8265-25.ucode failed with error -2 iwlwifi 0000:02:00.0: Direct firmware load for iwlwifi-8265-26.ucode failed with error -2 iwlwifi 0000:02:00.0: Direct firmware load for iwlwifi-8265-27.ucode failed with error -2 iwlwifi 0000:02:00.0: Direct firmware load for iwlwifi-8265-28.ucode failed with error -2

The wifi is detected by the kernel but still disabled. I went ahead and updated my kernel to version 4.11.86_64 and reinstalled the package iwl7265-firmware-22.0.7.0-49.el7 and wifi still remains disabled. I've uploaded a screenshot of my desktop so you can see that the wifi option is disabled (greyed-out) Original forum where I found the solution:

I guess a hard block can be caused by multiple modules and/or firmware trying to use the same device. Had to blacklist ideapad_laptop kernel module and reboot: sudo tee /etc/modprobe.d/nf <<< "blacklist ideapad_laptop" The contents of my /etc/NetworkManager/nf file are:

I am unable to understand why it's not working when the drivers are detected at boot using dmesg: iwlwifi 0000:02:00.0: loaded firmware version 21.302800.0 op_mode iwlmvm I've spent days on trying to get my wireless to work on my Lenovo Legion Y720.
