I have a Toshiba L755 laptop i bought back in 2010 brand new at Best Buy. This computer has served me well but lasy year there was a power outage and it took my computer with it. I thought it might be the internal power jack so i replaced that. Still two amber blinking lights. So it wasnt that. I understood the motherboard was prolly fried so I recently took it apart to see what would work...
I disconnected everything. I connected only the power switch and jack. So far, i had a working motherboard. I shut it down and connected the monitor. It still worked telling me i had no bootable device. I connected the battery and it started charging. So far so good. I connected the hard drive and it booted into windows. I connected the keyboard and it died giving me the two amber blinkies. I disconnected everything again because it would not start up again without the two amber blinkies.
So starting from scratch i did it again withoutvthe keyboard and it charged for a while and ran but died again.
I disconnected everything reassembled and left it alone for a while figuring it might be the battery... i started at ir again today and i had it running without hdd and battery. It will run BIOS. As long as i do not connect the hdd and battery i do not get the blinking amber lights... when battwry is connected, it goes to two amber lights and then a steady amber battery light so long as i unplug it from the jack. If i unplug it from the wall it still thinks it has power.
I installed the hdd and it tells me of a CMOS battery failure and the shortly after dies and gives me the two blinking lights again...
So what is wrong with it? I already figure i need a new motherboard, so i dont need that as an answer. I am wondering if it IS the CMOS battery causing all the issues or if its the actual battery... or if its the power supply to the system that is overloaded. I still have it running in BIOS and it will run as long as i dont connect a hdd (via usb or internal because i tried the usb way around) or battery to it.
