There are no major issues with Lenovo U330p. Everything works.

This page contains just some comments that may be useful during installation or troubleshooting.


The unit used here contained the following hardware:

  • Intel Core i5-4200U Processor
  • Intel HD Graphics 4400
  • 8GB of RAM
  • A thin Seagate 500GB hybrid drive (i.e. 500GB HDD + 8GB SSD).

Replacing the hard drive

Warning: this section is intended for documentation purposes only, and is not necessary to perform at all. Please be advised against opening the computer by yourself and performing operations that could damage the machine, besides making the warranty void.

The hard drive of this unit was replaced by a Samsung 840 EVO 250GB SSD. Other 2.5-inch SATA-3 SSD may be used, as long as it is not too thick.

For this purpose:

  • Power off and disconnect all cables.
  • Remove the 10 screws from the back cover of the machine.
  • In addition, remove the 2 screws where the back cover folds over to the other side. See Figure 1 on page 34 of the Hardware Maintenance Manual for this machine.
  • Double-check that all screws have been removed (12 in total).
  • Pull the back cover gently, until the two plastic latches inside it are released.
  • Unscrew the hard drive, but before pulling it out move away some very thin wires that may be placed over it. Do this very gently and carefully.
  • Insert the new drive and screw it, while rearranging the thin wires very gently.
  • Put the cover back on, and press it a little bit so that the plastic latches will lock. Then put the 12 screws back on their places. Use sufficient, but not too much torque.

For more info, please refer to the Hardware Maintenance Manual.


The best way to ensure that Arch Linux is correctly installed is to follow the Beginners Guide step by step.

Preparing the installation medium

Use another machine to download the latest image from the Download page and burn the ISO image into a USB stick by following the instructions in USB Installation Media.

BIOS setup

Before booting with the USB stick, enter the BIOS in order to prepare the machine for the new OS. For that purpose, press the small button on the side panel next to the HDMI port. A boot menu will appear. Select "BIOS Setup", and then:

  • In the "Security" menu, disable "Secure Boot" (although Arch Linux can be configured to work with secure boot, this will probably spare you a few issues during installation).
  • In the "Boot" menu, leave "Boot Mode" set to "UEFI", and "USB Boot" enabled.
  • In the "Exit" menu, set "OS Optimized Defaults" to "Other OS". Exit by saving changes.

Disk partitions

Use cgdisk to create the disk partitions, as explained in the Beginners Guide.

If the machine will be running Arch Linux only, then:

  • Create a first partition of 512MB (specify size: 512M) for UEFI. The partition should be of type ef00.
  • Create a second partition that takes up all of the remaining disk space. The partition should be of type 8300.
  • There is no need for a separate swap partition. Instead, create a swap file as explained in Swap.

Format the partitions as explained in the Beginners Guide.


Towards the end of the Beginners Guide you will install and configure a bootloader

If the machine will be running Arch Linux only, then gummiboot is simple and works nicely.

Video driver

Use xf86-video-intel. This is the correct driver for the hardware and it is being actively developed by Intel.

At the time of this writing (Dec. 2013), Intel has just released extensive information about this graphics hardware.


Install xf86-input-synaptics as explained in the Beginners Guide.

This will make sure that the touchpad works correctly and will also provide two-finger scrolling.

Desktop environment

Despite general criticism, GNOME 3 is an excellent choice. It can be installed smoothly (see GNOME) and provides a very productive work environment.

The Windows key takes you to the dashboard, where you can type to search for applications and use scrolling to move across workspaces. You can also tile windows on the screen easily, either by moving them to an edge of the screen or by using a combination of the Windows key with an arrow key.


Use of headphones

If you use headphones often and you shutdown the machine with the headphones plugged in, it may happen that in the next reboots the sound is directed to the headphones by default, even though the headphones are not plugged in.

(This problem seems to be related to the fact that Pulse overwrites ALSA settings.)

To fix this issue temporarily:

  • Plug the headphones in and out. The sound should now be directed to the speakers.

To fix this issue permanently:

  • Unplug the headphones.
  • Run alsamixer and use F6 to select the HDA Intel PCH sound card.
  • Set the volume level of headphones to minimum and the volume level of speakers to maximum (you don't need to touch the master level).
  • Run pavucontrol once (you don't have to do anything, just open and close it).
  • Reboot the machine (ensuring that the headphones are not plugged in). The sound should now be directed back to the speakers by default.

HDMI sound output

If you connect to an external TV through an HDMI cable and the TV gets image but no sound, you need to switch the audio output from the Analog to the HDMI sound sink.

If you're using GNOME 3, this can be done easily with a shell extension such as Audio Output Switcher.

Connecting an iPhone or iPad

There seem to be some problems in pairing with these devices.

However, if the only thing you need is to import photos from the device, you can do this with shotwell as follows:

  • Connect the mobile device to a USB port using the charging cable.
  • When the prompt appears on the mobile device asking whether the computer should be trusted, say yes.
  • Open Shotwell and by clicking on the left pane on "iPhone" (or "iPad") you will be able to import the photos.
