Lenovo ThinkPad T400s review

There is a new light version of ThingPad. This model has got very good performance considering its weight, not even the LED backlight is missing, there are SSD and eSATA...

At the end of the year new models of thinkpads are released, this model is comming with several changes, those are revealing what we can expect from the new models - redesigned keyboard, new connectors and brand new docking stations.

Letter 's' signs that it is a lightweight model. SOmething simillar can be found on the model X200 where the s version is lighter and inside is a classical processor replaced by ULV version.

At the first view the laptop is slimm. Some edges became round so the laptom is not so "box-like" as sometimes people say about the older models. Anyway design is still like the previous concept - the whole laptop is black without any contrast design parts.

I was afraid that due to the light weight and slimm design of the laptop the durability will be much lower. But that is not true - it is very durable laptop and the construction can whithstand very rough manipulation. The display cover is very slimm but even with the heavier press there are no waves in the LCD display.

The battery is in the front and therefore there are no connectors on the front panel. On the left side there is only combined input/output of a sound card and one USB. On the right side there is only DVD drive and that means all the others are on the rear (power, VGA, LAN, USB, eSATA/USB, Display Port)

The laptop is very well equipped, there is missing only FireWire but that one is missing on almost all laptops nowadays. Very important is the possibility of docking station, the new docking stations for this laptop can support two DVI or eSATA.

The target group are the people who needs maximal mobility but do not want to get rid of comfortable display and swift CPU. Majority of 14'' models is about 2,4kg but this one is only 1,78kg and dimensions 335x240x25-30. The power adapter is 345g including the cable.

Cooling system is very silent and even after several hours of full performance it is not going to be louder. It is one of the most silent laptops tested recently


The battery could last 5 hours and 30 minutes in a standard test. With maximum backlight and bluetooth turned on it could last 4 hours. The DVD can be replaced with a second battery.

+ silence
+ vcomfortable keyboard
+ excellent build quality
+ performance and equipment (DisplayPort, eSATA)

- baterry runs out quickly in sleep mode
- indication of power and battery charging is missing

Lenovo is one of the most trusted company. The Lenovo ThinkPad T400s has an amazing touchscreen. The keyboard is also very comfortable, typing is very easy. It is quite heavy in weight. The battery life disappoints a lot. People who are fond of gaming, this laptop is of no use. The only highlight is the amazing touchscreen. In terms of performance, its nice but not great.
