## Configuration

### Backlight

As of linux 3.16, backlight keys must be configured manually. [1] See Backlight for details.

### Hibernation

See Power management/Suspend and hibernate#Hibernation. Hibernation works with linux-lts (up to 4.1.21).

## Troubleshooting

### Overheating

There are some discussions concerning overheating-related shutdowns when running under full load (video encoding, etc). [2] [3]

Use the following thinkfanAUR configuration [4]:

    /etc/thinkfan.conf

    #X201 user specific
    #lvl    low     up      RPM
    (0,    0,      47)     # 0
    (1,    42,     57)     # 2000
    (2,    44,     59)     # 3300
    (3,    50,     65)     # 3500
    (4,    54,     70)     # 3500
    (5,    60,     73)     # 3800
    (6,    62,     83)     # 3800
    (7,    65,     88)     # 4300
    (127,  70,     32767)  # 5300

cpupower can be used for frequency scaling; see Cpufrequtils for more information. Undervolting is not possible with the Intel core iX cpu.

### No speaker output

Try pressing the mute button (next to the Escape key). See this article for details.

### No ACPI events

This article or section needs expansion.

Reason: Possible solution by using Coreboot? [5] (Discuss in Talk:Lenovo ThinkPad X201#)

After suspension, an EC IRQ may hang in the queue causing all functions keys to stop working. [6]

Other issues include the yellow USB port not being powered.

### Display issues

See Intel graphics#SNA issues and Intel graphics#DRI3 issues.

### Hardware virtualization

If KVM claims virtualization support is disabled in BIOS, even with VT-x enabled, disable Intel TXT. [7]
