Hello! I have been encountering problems lately with my MacBook Pro. I have a 2.4 GHz Intel Core 2 Duo, 4 GB 667 MHz DDR2 SDRAM, with Mac OS X Version 10.5.8. My Macbook Pro has acting funny lately, and I know something is wrong. When I open it, the screen is lightly 'blued' out, and then a horizontal panel with lights (bars) comes up at the bottom. Sometimes after this happens, I'm not able to use the mouse at all, and have to re-start the computer by pressing the power button. I've had to restart my computer recently quite a bit by pressing down on the power button and I'm aware that this is not the best thing for the computer. The computer is functioning slower than usual. This problem may be have been caused by the fact that I accidentally plugged in a 60 W adapter to my computer. I have to use 85 W adapter in order to power the machine. I think the battery in my computer is very close to dead. If I unplug the AC cable, my computer turns off. I've had to use the AC cable with the computer in order to power up the machine for many months now! I would love it if someone was able to help me out, and perhaps recommend what I could do to improve my situation. I use my machine for all my work and need it to keep on working for me! Please let me know if you have suggestions on what I can do to improve the performance of my computer, and get it working properly again. Thank you very much!
