I have a Dell Inspiron 5160 laptop. Was working fine, but now does not power up at all. When plugged in, I touch the power button and all three lights blink green for a fraction of a second. THen only the light on far right blinks ten times yellow/amber. Nothing else happens. What does this mean? Is it the power cord that's the problem or the internal battery? If I remove the battery I get nothing at all. I do not have a spare power cord or battery to test this further. Any advice? I've done some searches and see that this is a problem with 5100 Dells, but I can't seem to find a thread that will take me in the direction of correctly diagnosing the problem with my machine (and I need to fix this asap!) Thanks.
Thanks for the input/advice. Next time I'll call the Dell support line as you suggest to see what they have to say - I should have given them a chance. I have a friend who had a bad experience with Dell support, so I guess that's why I stayed away. For any of you who face this same problem, here's what I did. Although I'm a (complete) novice, I did some research and learned how to get inside the laptop, get under the keyboard and check all the connections, particularly the cable to/fr the battery, and also the memory cards. Interesting project for a novice, and perhaps quite a risky thing to do. But - to my surprise, my rather blind and tentative efforts solved the problem. I truly couldn't tell you what went right, but the once dead machine came alive, and is working perfectly well again. I can only surmise that some connection was not firing, and by disconnecting and reconnecting it, I got it matched up again. I'm now much the wiser, though, as a result of my research. I now realize that the problem may occur again and I may not be able to revive the machine again without significant cost and angst. I'm pleased for now to have a working machine, with no regrets about trying something new and different (that is, pretending to be the tech I'm not).
