hey friend I have been on google for about an hour now looking for a simpler way to solve this problem. its caused by a power failure.
if you have your battery out. while the computer is turned on and you unplug it. this will happen. its some saftey bs. how I get it to work again is by taking off the door to expose the ram underneath the wireless adapter.
there is a watch battery remove it and your bios resets and ur computer will work. you might need to re configure ur bios again. and ur system clock.
my computer will not boot with the function. sata native support enabled. if ur computer refuses to load after removing the battery try disabling that.
if you are unsure about where the battery is.
its the middle door. underneath the wireless adapter. the wireless adapter will have 2 antenna wires connecting to it. and be held down by 2 screws.
remove this and u will see the battery. remove the battery and put it back together.

took me forever to figure this out.
enjoy ur working again laptop.

Tarek,

I had the same prob but removing the battery (and putting it back) did not help. I even tried taking the batt out completely and tried booting. If the battery (small MB batt) is dead would this cause the computer to not boot but only show the power light and volume buttons etc to light up?

According to his problem fan for five seconds then a blinking light it is a bios reset. But if the lights come onsteady and nothing shows on screen it is probably the motherboard you can go as far as plugging in an eexternal moniter .

Although in some scenarios resetting the bios may solve your problem.. In most cases the problem is your video card which unfortunately is integrated into the motherboard. The video card will not post (show a display) because it has failed. This seems to be a relatively common problem in the DV5000 to DV9000 range of hp laptops. I have ran into 3 identical scenarios in the same week, and one of the new motherboards did the same thing after one day. Supposedly one of the main reasons that the video cards in this particular series fail has to do with the heat from the processors heatsink passing across the video card.

yes I agree with cmnetworx on that wone corwin. reseting the bios only works when is bios related. (push power button light flashes 3 times) but your problem sounds like a video card. you say you turn it on and it powers up but don't see anything. in this case you should log on to ebay and order a specific motherboard for your computer and have someone skilled install it. if you plan on doing it yourself remember group all screws with specific parts do not force anything theres always a hidden screw or the part slides up. hope you have success my laptop died twice already once from dropping and the other from getting rained on. both times I had to replace the motherboard.

by the way the watch battery is for keeping clock and bios settings if it were dead it would simply lose time and bios settings everytime you unplug it. but would not keep your computer from booting.

also to help diagnose if its power related. try powering on with your power battery out and your laptop plugged in. if there is no response then its obviously power related.

hi, friends,
please better contact between the heat sink and chip set, as well as the heat sink of the processor , replace the thermal pad between the chip set and and heat sink. Usually it works.

Hi mickey's this problem is common in this type of laptops

you can follow the step to solve this problem
1) remove battery and hdd cd rom and just plug the power adaptor
and press power on switch for 20 sec and then remove the power jack and re plug and power on if it solve the problem it great or go to step sec
2) remove ram (memory) and just clean with eraser this problem 50 to 60 % coming due to bad ram or bad ram slot or dust on ram slot if it solve ok
3) if this do not solve the problem then if you are technical guy you can open the laptop just dismental all laptop remove cpu cmos battery ram hdd cdrom etc and keep open as it is for 5 minuts and repack the laptop hope this will solve the problem if still no joy then this is a mother board or ram problem you get to a laptop service center to get solution you if your laptop is under warrenty do not open the laptop give to company for repairing

I have been having the same problem with my dv5000

I've removed both the main battery and the BIOS battery and put them back in place after a few minutes. when I push the power button I get a screen asking to "Press F1 to continue, F10 to setup".

If I press F1 it goes to a blank screen and does nothing, If I press F10 I get into the BIOS and I can change any values I want to and save them but when it tries to reboot it does nothing and just sits at a black screen, no beeps or start up screen of any kind.

I'm thinking it is a bad motherboard at this point in time.

Thank you, Redbay

Just had a similar issue on my coworker's HP Probook 6460b (blinking power light, no startup), we pulled out the ram card, cleaned out the dust with compressed air, put ram card back in, plugged in AC Adapter and left battery out, and held power button down until computer started. It worked!

What I did that worked great was pushed power button 40-50 times and then held the button down for a min or so and plugged it back in and it started working again

...be sure that, it IS !

...Couple of months ago, I did EXACTLY what you described here some 6 years before :
"its caused by a power failure.
if you have your battery out. while the computer is turned on and you unplug it. this will happen. its some saftey bs".

I namely (while already having taken its battery out) was running an HP G3000 laptop on its AC adapter and accidentally took the adapter's plug out of the power socket, only to realize soon enough that after this, that the laptop wouldn't power on again. No matter what I tried, its power indicators (either for DC or AC) kept on blinking continuously when pressing the power-on button.
I of course thought that I probably fried the motherboard (or at least some circuit or component that managed the supply of power), since the adapter, RAM modules etc seemed to be working fine (I also tried to troubleshoot the situation by taking of "portable" parts like the HDD and the optical drive, to no avail. Same thing with attempts to discharge possible static that possibly remained in the system, by taking the battery and adapter off and continiously pressing the power-on button and blah-blah-blah).
My last chance before sending it for service (and weeping over the money that I couldn't actually afford for this) was to take off the CMOS battery off. But since I DIDN'T remember that I once took the wireless card off and noticed that beneath it laid the lithium battery in question, I kept thinking that I "one day have to try take the laptop apart to get to the CMOS battery". Weeks and months passed and I meanwhile put together an old P4 as a replacement. Which is far from being efficient, compared to the double-cored CPU of the laptop (online life has become hell since, especially considering YouTube, which has apparently gotten too "heavy" nowadays for P4-era machines. Thank god I'm not into Facebook anyway, because I guess there things would be much worse for me, from what I hear).
Until a couple of days now that I decided to check for related-to-mine issues. Needless to say that I came across tons of useless info, pointlessly watched many YouTube videos (which were lengthy ones too), until I stumbled on that post of yours, citing EXACTLY what I was facing, like I already said. And it reminded me that the damned CMOS battery must have been under the wireless card and I didn't have to take the whole thing apart.

So I took the wireless off, extracted the battery, put it back on after a few secs - and what do you know, the laptop is back...

On a sidenote, I was AMAZED that no matter the variety of the search terms I used, I didn't come across some damned post of HP's, describing the very situation..... I did see the "CAPS LOCK & NUM LOCK LEDs blinking" troubleshooting suggestions in various occasions, yet nothing about "power/adapter/ indicator flashing/blinking continuously" what-the-hell-ever.
Actually, nothing more (considering HP's troubleshooting guides) than a mention that "this means there's a problem with power utilization". Ah, yeah, "thanks so much", "too much help from you", HP...
THEY SHOULD EFFIN POST THIS WITH CAPS IN THEIR SITE'S HEADER, THAT WHEN ONLY IN AC AND POWER IS ABRUPTY DISRUPTED, LAPTOP BATTERIES SHOULD BE TAKEN OUT AND BACK IN.
(...)

A REAL, HUGE thanks to you eek, however.
If not for anything else, at least for prompting me with your post to take the wireless card off.
