T-series of ThinkPad is known as a masterpiece of notebooks.
After being sold to Lenova, this reputation doesn't fade yet.
If you want a powerful and portable notebook, this model may be the best choice.
Heat: very good. I cannot feel hot although I usually use it all night long. I think its cooling system is very efficient.
Noise: good. Fan often works, but its sound is durable.
LCD: not bad. It is bright and clear, But, if you worry about your eyes, I recommend that you choose other models whose maximum resolution is 1024*768. This model also support 1024*768, but pictures are not sharp in this resolution.
Keyboard: very good. Its keyboard is very comfortable. It has separated function keys such as insert, delete, page up, page down, and so on. Since I hate duplicated key arrangement, I satisfy this keyboard very much.
Battery: very good. I use it for about 4 hours without the power cable.
Fingerprint reader: good. In order to be familiar to this reader, you should try many times, but after being familiar, the reader is very convenient.
Weight: not bad. This is subjective. If you want a very light notebook, I recommend you to avoid choosing this model.
Size: bad. Overall size is good. However, this model has 9-cell battery. You must keep it in mind. 9-cell battery protrudes from the 14” rectangle. I bought a 14" sleeve for it, but this sleeve is not suitable because of the battery.
