Hi. My original Sony Vaio-394L battery is 100 percent dead. I bought a new one but someone misplaced the installation CD. I know I need the CD as I need to follow instructions and presumably may need some software updates. Trouble is, I cannot find ANY downloadable info such as the correct Installation CD or a PDF. I can´t even find info specific to the 394L model; the laptop was purchased from a legit shop so IS an original SONY and the model numbr is from the manufacturer´s label under the laptop. Can anyone point me to instructions on exactly how to replace the battery plus links to pertinent software upgrades I have to install? Thanks for any help.
