Abstract: Disclosed are method and apparatus for improving battery performance by transferring waste heat generated from heat generating components to the battery that, when brought to a high temperature, attains better performance according to temperature characteristics of the battery. According to the disclosure, an electronic device capable of effecting improved battery performance comprises a central processing unit generating waste heat when being operative; a battery for supplying power to said electronic device; and thermal conducting means, first end thereof making thermal contact with said central processing unit and second end thereof making thermal contact with said battery, causing heat transfer between said central processing unit and said battery. Said waste heat generated by said central processing unit is transferred to alter the temperature of said battery such that its output voltage is stabilized and capacity enlarged.

Abstract: A computer system with an EMI prevention structure includes a housing for covering a main board. The housing has leading grooves formed on two opposite inside surfaces. The main board includes a ground layer formed on the periphery, attached shielding devices corresponding to the leading grooves, a thickness of the main board and a shielding device being substantially equal to a gap formed by a leading groove. Each shielding device has a pair of substantially parallel metal plates and a metal side plate forming an open rectangular channel, the open side allowing the shielding device to fit over the ground layer of the main board. A spring latch is installed on a plate of each shielding device to allow the shielding device to remain firmly fixed to the main board.
