ASUS N61J Laptop - Change the BIOS battery.

My ASUS N61jA laptop has been loosing time and date recently, so I decided to change the battery. The battery is located under the top side of the case. You need to take it all apart to get to it. 00:00 - Intro and screws to remove 02:06 - Pictures of screw locations 02:22 - Removing the keyboard and other connectors 05:41 - Removing the top and getting to the BIOS battery At the 02:06 mark, the three pictures are as follows: Picture 1 - All the yellow dots are the case screws, the red dots are for the access panels and components. Picture 2 - The top section with the corresponding yellow dots and the green dots are the ones under the keyboard tray. Picture 3 - The 4 green dots are to be removed after the keyboard is taken out. The matching colour outlines are to just show what the connectors connect to. Some notes on this laptop; I bought it in 2010, it is still good today. It originally came with an i5-430m and 4GB of memory with a 500GB HDD and Blu-Ray player and a single USB 3 connector. The GPU is a Radeon 4370 with 1GB dedicated memory. I have upgraded the CPU to an i7-740qm, the 2 pipe heatsink cooler to the 3 pipe version, 16GB of memory, a 128GB SSD, a 2 port USB 3 express card, put a 32GB SD card into the SD card reader and the original 500GB HDD into an external USB 3 case. The CPU upgrade made me have to modify the BIOS to handle the CPU microcode. It now has the n61jQ BIOS in it. At the time they made the i5-i7 model lines of these laptops with the same base...
