Design
At first glance,inspiron 6400 battery the T400s looks like any other ThinkPad: black and rectangular. If you look a little closer, you will notice the subtly rounded edges, surprisingly thin profile, and very non-T400 port placement. The T400s brings in a number of design cues from the super-sleek X300/X301 models, including the same material construction.xps m1330 battery Carbon fiber is used for the top cover, with a unique glass fiber for the edges of the top cover to allow for un-diminished wireless signals. You'll find a magnesium alloy in use on the bottom cover and keyboard bezel,dell d620 battery adding to the chassis stiffness provided by the internal magnesium roll cage.
Open the black rectangle and you will see a familiar sight with a few tweaks.HP 510 The TrackPoint and toucpad are redesigned with usability in mind, featuring larger TrackPoint buttons and a larger,Acer Aspire 4710 textured multitouch-capable touchpad. Some of the system information LED's have been redesigned and consolidated, leaving you WiFi, Bluetooth, and hard disk activity LED's in the LCD bezel. However you also now have a Caps Lock LED on the key itself, mute and mic/webcam disable buttons with status LED's, and the power button slowly blinks to indicate the system is in standby.HP Pavilion DV9000 These complement only two LED indicators on the exterior: a battery icon indicating AC power, system powered on, and battery status along with a sleep icon. Lenovo also updated their keyboard design, you will see the enlarged Esc and Del keys which have altered the layout.Sony VGP-BPS8A I will discuss more on that later.
The hinges are still silver, unlike the black metal hinges present on the X300/X301 models,Sony VGP-BPS8 and the speakers are placed on either side of the keyboard for optimal listening. Many people took exception to the T400's off-center 14-inch widescreen, but the T400s has a centered screen. If you take a look at the bottom panel,Sony VGP-BPS9 you will see a fairly clean chassis with a single expansion cover to remove and standard 6-cell battery integrated into the front of the machine. Note that there is no room for an extended battery with this design.Sony VGP-BPS8B
Size and Weight
Having spent a lot of time with a regular T400,Sony VGP-BPS9/B I can say that it is a bit on the portly side. Most configurations will weigh in at over 5 lb and it is about 1.1-inches thin. Combine that with the dimensions of a 14-inch widescreen and it is quite unwieldy as a portable machine. The T400s is like the T400's skinny relative, weighing in at only 3.91 lb and a mere 0.83-inches thin.Sony VGP-BPS10 That difference in numbers really adds up when you get it in your hands. Thanks to the advanced materials and internal roll cage, the T400s is not only thin but incredibly rigid as well.Sony VGP-BPS9/S Picking it up by one corner feels exceptionally sturdy and lightweight, like a heavy duty (paper) notebook.
Keyboard and Touchpad
ThinkPads have always been crowned as having the world's best keyboards and the T400s continues,Acer UM08B71 if not elevates, that lineage. The full 7-row layout is still present here and the typing experience is immaculate.apple a1060 battery Tactile response, key travel, and general stiffness are all amazing. Some of the regular T400 systems were plagued with extremely spongy keyboards, but the T400s looks to be void of any such problems.apple a1045 battery Ignoring the layout change for a moment, Lenovo also enlarged the size of the base of the keys to reduce any crumbs and such from getting in the keyboard tray. This doesn't affect the key spacing itself, it appears they simply added more of a sloped base to each key to fill in the gaps; it appears to be a rather effective technique.
As I alluded to earlier, Lenovo did change the keyboard layout a bit.Dell inspiron 1525 battery They did a study and found that the Esc and Del keys were highly utilized, but also a bit harder to use accurately and efficiently. To help remedy this, they enlarged the Del and Esc keys to nearly double their previous dimensions. To make room for this, they did have to compress the Function keys a bit and move the Ins key to the top row of the keyboard. In my experience typing on this machine, these changes were not overly detrimental.Dell latitude e6400 battery I found reaching for some of my common Fn combinations with my left hand to be trying, as I was always a key off from what I intended. Also users who relied on the Ins key will be very affected, as it is in a very distinctly different position now. I personally never had trouble hitting the Del and Esc keys, but I can see how this change would help those with smaller hands or who had other accuracy problems.
For those of you not familiar,Acer BTP-60A1 the TrackPoint is Lenovo's "pointing stick" device that provides the same functionality as a mouse or touchpad. The red nubbin acts like a joystick and for those adjusted to the device, it proves to be highly accurate and allows you to mouse around without removing your hands from your typing position. The TrackPoint mouse buttons have been enlarged and softened a bit,Toshiba PA3399U-1BAS with more of a curve than the sharp peak on other designs. I did not find this to impact my usability at all and I don't think anyone will have trouble adjusting.
The touchpad is another area Lenovo changed in the name of usability.hp pavilion dv6000 battery In an effort to keep the system as thin as possible, the touchpad was brought flush with the palm rest and given a unique texture to differentiate from the palm rest. It is also larger than the rather small one found on regular T400 models, and now support multitouch features.Fujitsu lifebook s6510 battery The T400s' touchpad is incredibly responsive and natural to use, with a sufficient surface area to be comfortable and efficient.
Display Quality
ThinkPads are traditionally business models and aren't exactly known for high quality displays.Sony VGP-BPS13A/B A few models had exceptional LCD panels, but most are just average, including the regular T400.Lenovo/IBM ThinkPad T60 The new T400s uses a 14.1-inch 16:10 ratio widescreen LCD running 1440x900 resolution. This LCD is exceptionally bright, with plenty of brightness steps to find the optimum level. When viewing at the sweet spot angle, you will be in love with the T400s' screen. It is bright, vibrant, and features crisp, dark blacks. Unfortunately, like most ThinkPad LCD's and many matte LCD's too, move about 5-10 degrees off the centerline and you dramatically lose dark details. Advance much further and you will see significant color inversing, although light colors remain in good contrast throughout. There is enough of a sweet spot on this panel that you won't constantly be fidgeting, and the brightness and colors really are superb, but the T400s' display doesn't quite impress.
Ports & Connectivity
Despite being uber thin and light, the T400s has literally every port or connection you might need.Lenovo/IBM ThinkPad X60 Every acronym and abbreviation you can think of is included for wireless: 802.11a/b/g/n WiFi (with three card choices), Verizon or AT&T WWAN, UWB, Bluetooth, and WiMAX. Ethernet is included as well, although the prehistoric modem has been dropped and you can get a USB model if you need it. You'll get 3 USB 2.0 ports on the T400s, including one that doubles as an eSATA port, and the choice between an ExpressCard34 slot or 5-in-1 card reader.
