I actually have an HP Elitebook 8470p but its similar to the 8460p. Currently it has this random issue of not powering on and I don’t quite understand what the LED lights mean. Typically I can get it working by removing everything (ram, battery, cmos battery) and reinstalling the items until it runs again but its kind of annoying of having to do it everytime. Also note the orange LED light does not show even with the battery plugged in (idk why) although it still charges the battery. Someone else mentioned the possibility of it be a dying motherboard but I wanted to see if its possible to fix it rather than buying a new one. Here is a video of what it does when it can’t seem to power on.
First of all here’s the link to the service manual so you can read it: https://support.hp.com/nz-en/product/hp-… Meanings of lights pages 21. Power Light - going off means computer is off or has gone into hibernation.AC adapter/Battery Light - White: the computer is connected to externalpower and the battery is charged from 90 to 99 % and Amber with adapter means battery is charged 0 - 90% What do the lights do if the AC adapter is unplugged and you try to turn it on? What do the lights do if the AC adapter is plugged with the battery removed and you try to turn it on? I am hoping “Typically I can get it working by removing everything (ram, battery, cmos battery) . . .” you did not remove the components in the order you listed above. Adapter, then battery always first thing. Did you remove battery and hard drive and try turning on with just the adapter connected? Did you take out both RAM modules and then try one at a time in each slot? Let us know how it goes.
