## Hardware configuration

### Graphics

See Intel graphics.

### Input devices

#### Touchpad

Touchpad is SynPS/2 Synaptics TouchPad. `evdev` input driver provides basic functionality, but for tapping, scrolling and other advanced functions xf86-input-synaptics should be installed.

See Touchpad Synaptics.

#### TrackPoint

See TrackPoint.

### Network

#### Bluetooth

See Bluetooth.

#### Ethernet

Ethernet controller is identified as `00:19.0 Ethernet controller: Intel Corporation 82567LM Gigabit Network Connection (rev 03)` and works out of the box. The corresponding kernel module is `e1000e`.

#### UMTS

This article or section needs language, wiki syntax or style improvements.

Reason: please use the first argument of the template to provide a brief explanation. (Discuss in Talk:Lenovo ThinkPad T400s#)

This article or section is a candidate for merging with [[]].

Notes: Out of scope, move to a page in Category:Modems? (Discuss in Talk:Lenovo ThinkPad T400s#)

The UMTS device is a Ericsson F3507g MiniPCIe WWAN/GPS card. The vendor identifier is 0bdb, while the device identifier is 1900 (both values are hexadecimal values). You can get more information about the card by using lsusb/usbview. In order to use the UTMS modem you will have to activate the device. You can edit and verify the settings of your UMTS modem by using minicom or another terminal emulation program like picocom or dterm. I've used tinycom which is inspired by the well known FreeBSD program 'tips'.

##### Activate the UMTS device

Open a connection to the device:

    # ./com /dev/ttyACM1 [115200]

Check whenever the SIM is protected by PIN by sending

    AT+CPIN?

If the answer is:

    +CPIN: SIM PIN

you will have to unlock the device with your PIN:

    AT+CPIN="YOUR-PIN-NUMBER"

The device can be activated now by sending:

    AT+CFUN=1

The answer of the device should be:

    +PACSP0

##### Restrict communication to GSM

Normally you do not want to restrict your communication to GSM only. If desired, you can send:

    AT+CFUN=5

##### Restrict communication to WCDMA

As before, it is unusual to restrict your communication to WCDMA only. Type:

    AT+CFUN=6

##### Deactivate the UMTS card

You can deactivate the card by typing

    AT+CFUN=4

and if you want to remove all power from the card, type:

    AT+CFUN=0

##### Setup the UMTS card as modem

There are two ways to use the UMTS card as modem. The first one just uses the card as GPRS modem, the second one uses the card as CDC ethernet interface.

###### Setup the UMTS card as GPRS modem

The GPRS modem settings are configured by wvdial. Please note that there are provider specific namings for access point names (APN). You can find an appropriate APN over here.

###### Setup the UMTS card as CDC ethernet interface

##### Setup the UMTS card as GPS receiver

While the UMTS card is activated, we can use it to get GPS info via NMEA protocol. In order to use the NMEA protocol, a few things have to be configured

    AT*E2GPSCTL=X,Y,Z

The parameter x activates/deactivates the NMEA stream. Legal values are 0 (off) or 1 (on). The frequency how often the card emits the NMEA sentences is set by the Y parameter. Legal values are in a range between 1 upto 60. The last parameter sets DGPS off or on. The value 0 turns it off, the value 1 turns it on. If you want to activate the NMEA stream and DPGS and to update the position every 42 seconds you would type the following:

    AT*E2GPSCTL=1,42,1

This article or section needs expansion.

#### Wireless

Both 'Intel Corporation Wireless WiFi Link 5300' (2815W3F) and 'Intel Corporation Centrino Wireless-N 1000' (2815RH1) adapters are supported by iwlwifi.

See Wireless network configuration#iwlwifi.

### Web camera

Web camera (USB ID `17ef:480d`, Lenovo Integrated Webcam [R5U877]) works out of the box. It is supported by `uvcvideo` kernel module.

See Webcam setup, Integrated camera.

### Sound

Sound works out of the box. The corresponding kernel module is `snd-hda-intel`.

As of September 2010 the module must be loaded with the option `model=thinkpad` in order to get the earphones work:

    /etc/modprobe.d/alsa-base.conf

    options snd-hda-intel model=thinkpad

This is due to the update to kernel 2.6.35. See [1] and [2]. This also enables muting of the internal speakers when a speaker is attached to the docking station.

## Troubleshooting

### 9 seconds reboot delay

You may want to append `reboot=pci` to the kernel parameters list.
