Hi guys ; I need help in this one . I had this Laptop for repair yesterday . It seems i wasn't the first one to check it . Someone had removed the battery bios and a 8 pins chipset labeled U4 near it .. The Laptop is Lenovo 3000 N100 model 0768 . the motherboard is 41W1200 Core Duo 15.4inch ...
Can anyone know to identify the u4 ?

It's my last hope before ordering a new one ...
