Since I am in Oita, southern part of Japan, where there is no HP center nearby, I am confused of what to do with my HP notebook issue. First, for the past few weeks, the laptop could not survive long without AC adapter/charger, otherwise it will suddenly shutdown and showed the "CMOS checksum is invalid" black screen. Two days ago, the "PC run into trouble" blue screen suddenly appear when I was using my PC. And this morning, my laptop was not able to start and the caps lock button blinked 3 slow blinks and two fast blinks. Please tell me what should I do with this issue

 

Thanks
