orange light, which idk what that means.  it means 5v standby works but not that the power supply is good. [URL]   The Green LED on the back shows power available not power supply is ok. Not all models have BIST Built in Self Test button. [URL]   CMOS battery is likely dead and at least part of the issue. [URL] Most grocery stores have these but YMMV [URL]  
Well, I have been experiencing some issues with this Inspiron Dell 530s of mines. It hasn’t been touched in a few months or so since I left with my grandparents. I finally remembered that it there and attempted to see if it worked. And which case it did, but I had to work on it a little bit. Now that I have brought it with me back home i have been experiencing the same problem once again. The Dell 530s isn’t like turning on when I press the power button, it’s like the thing is completely dead. But when I take it apart I see a orange light, which idk what that means. After a while I simply gave up and now is trying to see if you or someone else can help me out this problem. I followed the steps with removing the rams and cleaning it out, also removing the dust from the fan as well. Still isn’t turning on- The power button is blank when I press it. And I look on my monitor to turn it on it goes directly into power saving mode. please give me a response of an solution..
My Inspiron 530s is acting strangely
