Company IBM has found a way out of a difficult situation by cooperating with concern Lenovo, after it had had problems. Owing to this cooperation there were new ideas which were shortly put in a reality. Appearance Lenovo/IBM in the world market of the laptops has made huge furor. For two months it has been sold over one million of the laptops all over all world. Everything was worked up to trifles. The power supply system of the laptops praise is deserved a special praise, which consists of two storage batteries. It will keep balance of the power supply system of the laptop, if one of these accumulators will be unloaded or will fail. The operating time of the laptop increases both at active, and at passive using. Still up to cooperation with Lenovo company IBM used in its laptops NiCd-batteries which capacity did not exceed 1.7 A/h, and a cycle charge/recharge time reached a mark in five hundred times. Also these laptop batteries were characterized by presence of effect of memory at incomplete cycles. However, now NiCd-batteries, practically, are not used anywhere. Nowadays IBM network adapters use tremendous success. They showed the best qualities as today they are considered as the most reliable adapters in the world. One more advantage of adapters IBM is the opportunity to use them at additional charge not only of the laptops this firm, but also Portable computers of the nearest competitors (ASUS, Toshiba, HP).
