Lenovo Thinkpad T400 Duo Core 2.40Ghz

Price is low (Potato price) and fixed. Please do not bargain with me. I am not professional seller. This is my personal laptop I sell it at very low price due to following reasons:
01. Battery cannot bear long time.
02. Keyboard is missing two keys which were removed by my 2.5years old baby.
03. Laptop fails to enter sleep mode (probable due to software reason). All other functions are OK.
04. I have enough laptops to use.
Laptop conditions are as per photos shown. Please check the photos carefully and don't call me if you are not sure to buy it. Please speak English as I am a foreigner.
