Battery Conservation Mode is a feature that limits battery charging to 55-60% of its capacity to improve battery life, being most useful when the laptop tends to run on external power much of the time. This works on many Lenovo laptops like IdeaPad and Thinkbook series. To check if your laptop is supported, try to set the battery conservation mode in the Vantage app on Windows. If it works on Windows, it can be enabled or disabled on Linux in the following manner:

To solve all these issues mentioned here easier just install the latest BIOS update from Lenovo support website. Missing IVRS map in ACPI Table, add amd_iommu=pt ivrs_ioapic[32]=00:14.0 in kernel parameters. In order to get X to work correctly, add iommu=soft in kernel parameters (Linux 4.20 only). In order to get microsd (SDHCI) working, echo "options sdhci debug_quirks2="0x8000"" > /etc/modprobe.d/sdhci.conf and change module load order MODULES=(sdhci sdhci_pci) in /etc/mkinitcpio.conf (line 7). Do not forget to run mkinitcpio -p linux afterwards. Bluetooth does not work until a suspend/resume cycle occurs.

I have managed to connect two external monitors (in addition to the built-in panel) to my ThinkPad T430 on Ubuntu 13.04, with Optimus ("Switchable graphics") enabled (option 3 in your list). The monitors are connected via the DVI interface, one of them is rotated. In contrast to other solutions, all monitors are attached to the same window manager, so windows can be moved freely between the monitors. This achieves the goal of enhanced battery life if disconnected and using external monitors if connected.

The problem is that the laptop uses LVDS to talk to the TN screen, while newer screens are likely to use Embedded DisplayPort (eDP) which is a different protocol entirely. However, there’s now a converter that [Syonyk] found on eBay (from China, of course). For about $70, the motherboard’s LVDS output can transform to eDP. Of course, you also need an IPS display panel.

I recently purchased a used Lenovo Thinkpad T420 laptop to replace the Lenovo Thinkpad T400 I was previously using as my main platform for researching open-source network simulators and emulators. The T420 is a five-year old product but it offers all the ports and performance I need. Because it is well past its depreciation curve, anyone can purchase a used T420 for a very low price.

I wanted a computer that supports high-resolution external monitors so it required a DisplayPort output. I also wanted to expand the number of VMs I can run concurrently with adequate performance so I needed a processor that supports HyperThreading. I wanted to switch to the Ubuntu Linux distribution and the Ubuntu Unity desktop environment needs just a bit more processing power to run smoothly. The Lenovo Thinkpad T420 meets all these requirements.

The Lenovo Thinkpad T420 is a business-class notebook produced in 2011 that was leased in large volumes by companies for use by their employees. Now, these companies are returning these computers to the leasors so Lenovo T420 laptops are available at used-computer re-sellers and on eBay at very low prices.

When purchasing a used Lenovo T420, you need to be aware of what you will get for your money. The Lenovo Thinkpad T420 was originally produced in many different configurations. When comparing prices, take into account the features added to the computer.

When looking for a used T420, I suggest you purchase a model with the 1600×900 LED screen. Other parts of the T420, such as the hard drive and memory, are easy to upgrade. Some models of T420 come with a discreet NVIDIA graphics chip, which is not important for most users so don’t pay extra for it. Some models offer a fingerprint reader, which is a convenience.

Upgrading memory on a Thinkpad 420 is very easy. When Lenovo installs the base level of memory in a Thinkpad, it only uses one memory slot so it is inexpensive to upgrade the laptop to 8GB by purchasing one more 4GB DIMM — and the second slot is very easy to access.

Replacement parts for the T420 are still available and Thinkpads are made to be easily repairable. You can download the T420 maintenance manual from the Lenovo web site. For example, the T420 I purchased has a few keys on which the letters are fading. If I decide to replace these keys, I can find multiple online stores that sell replacement keys just by searching for “thinkpad T420 key replacement” on Google.

The T420 I purchased was a well-equipped model with the Intel i5-2540M processor, a 1600×900 HD+ LED screen, Intel HD Graphics 3000 and NVIDIA NVS 4200M discreet graphics with Optimus graphics switching technology, a fingerprint reader, a webcam, 4GB memory, and a 320 GB 5400 RPM hard drive. It also has four USB2 ports, a Firewire port, a VGA output, and a DisplayPort output that supports an external monitor with up to 2560×1600 resolution. It came with Windows 7 Professional already installed.

As mentioned above, the T420 I purchased has an NVIDIA NVS 4200M discreet graphics chip. In Windows, the laptop will switch between the Intel graphics and the NVIDIA graphics as required by programs running. Unfortunately, the graphics switching technology does not work well in Linux so we must do some extra configuration to enable manual graphics switching, or just disable the NVIDIA graphics in the BIOS settings.

The T420 I purchased came with Windows 7. When I booted up Windows 7, it offered a free upgrade to Windows 10. I chose not to upgrade to Windows 10 because it is not clear if the NVIDIA Optimus graphics switching technology will be supported in Windows 10.

Lenovo does not officially support the T420 with Windows 10 so they will not provide updated Windows 10 drivers. Without the right drivers for the NVIDIA chip and for power management, battery life may be much shorter in Windows 10.

For now, I will keep Windows 7 so that the NVIDIA switchable graphics and Lenovo power management features continue to provide good battery life when I run Windows.

I am very pleased with the performance of my used Thinkpad T420 laptop when running Ubuntu Linux. In two or three years, I will upgrade to a Lenovo T450 or X1 Carbon when those models are close to the same US$200 price point that the T420 is at today.
