2 Batteries 9-cell (97Wh). First battery reports wear of 15%, second battery reports wear of 44%. Batteries can only be used one at a time. Life not guaranteed. Wear provided as a courtesy and estimate of life remaining.
2 220/240w power supplies
1 Dock. This is the PRO2X I believe. It was the best available when I researched, and it has 2x USB 3.0 ports, and 2 DisplayPorts. I had the displayport putting out 4k resolution at 60 hz to a Sony 4k TV.
1 Dock stand elevator. I used this to elevate the screen so that the laptop screen could be used as an extra monitor at my desk setup.

Input: Anti-microbial keyboard with number pad: Backlit
Touchpad: Fingerpoint ball in keyboard, as well as traditional trackpad. All buttons and keys work, but the left-click button below trackpad has lost of of its springback, so it rests lower and has less feedback when being clicked. It still functions properly though. Palmrest also has a crack in the plastic (see pictures). Both the trackpad button and the crack could be fixed by replacing a $25 trackpad/palmrest assembly that is the same part #.

Has signs of use. This is a clean system, but it does have scuffs and dents on the chassis (a testament to the durability of these Precision models).

Laptop was used for portable gaming and as the general use computer for my wife and I. I recently upgraded a desktop, and this laptop no longer sees use.

Laptop was purchased originally from Dell off-lease in February 2015. I replaced the i7-2640m with the i7-2960xm, replaced the m8900 gpu with m6100 gpu (m6100 is both faster and more stable than M6600s with the m8900 gpu), replaced the RAM, replaced HDD with Samsung SSD, and replaced the wifi with Intel AC wireless. This laptop has been a solid mobile performer, but I am letting it go due to our changing situation and no longer having a need for such a powerful portable system.
