One possible reason could be also that we need to open the covers of the laptop "HP 9470 led power blinking" and use a air spray in order to push out all the dust from the fans and all other chips. We leave the laptop to dry out for at least 30 ~1 hour without memories on , battery ,no ac plug on. Before placing any charge on it press the power on button for 15 to 30 secs and then start assembly the laptop again. At least for me worked that and the real problem occurred due to the dust on the fans. Hope it works...for U too.

Could be one of several possible reasons. (the most likely is not promising)
Firstly, remove the battey and try it on mains power only, if this works, the battery is so badly faulted, it is causing problems in the laptop booting.
Secondly, remove each RAM module in turn and see if it boots with one ram stick, if it does, you have a defective module
Thirdly, and with HP laptops, most likely, the blink sequence you describe is related to the graphics chip. If the laptop was getting hot before this happened, its a fair bet that the chip on this has unsolderd itself (will need reballing). Google and you'll find the V and DV series which were fitted with the Nvidia chipset, were prone to this and the result of a lot of returns to HP. If it is still under any warrantly, i'd take it back, as this problem is not fixable easily

Go to your product vendor.they will resolve this
SOURCE: I am having difficulty obtaining
Base System Device drivers are usually installed by what the manufacturer calls "Chipset" drivers. If you are running Windows XP, there is an Intel Chipset driver available at the Lenovo Support Page for your model. If you are running an Operating System other than Windows XP, I would go to the above page and compare the drivers listed there with what you are seeing in Device Manager. Install the ones that are missing. Hope this helps!

Compaq and Hp are having issues with several models, My wife just got hers repaired free out of warranty. Go to copaqs website, look up your model and see if it is one they are offering free one time repairs on. Wife's computer was doing same thing, they replaced the motherboard. Took about 2 weeks round trip . Good luck

It would seem that your BIOS has become corrupted somehow. First try entering your BIOS setup. I believe for HP computers when you press power tap the F10 key until it opens. There you can try to reset them in some fashion and save. Try rebooting. If that fails then remove the battery and repeatedly press the power button for about 10 seconds.. (make sure it is also unplugged, this is to discharge the power from the system) then replace the battery and try booting again. Otherwise it would seem that you might have tried to load the wrong BIOS into your laptop. Check with HP then if you are still covered or not. :/
