Default Hp Laptop DV6000 turns off and on

The power supply plug from the power supply went bad on this notebook. bought a replacement plug from Ratshack and blue light lit and all is fine, right?

Wrong!

I then try to power up unit and the blue lights above the keyboard will light only for a second and then shut off!

You can press the power button all day long and those blue lights will light, just for a second, and then go off.

The battery seems to have charged up some, in that I can disconnect the power supply and the same on~off situation occurs with JUST the battery for a power source.

Did a google and some said, 1) remove battery hold power button down,2) remove cmos battery, 3) check memory. tried all of those and NFG!

I then read some replies to my google query, and read that the video chip may have overheated and unseated a fews pins? Are they serious?

Anyhow/way can some one shed some light on this problem?

thanks

Default Very common issue with those laptops, prob needs to be serviced

HP Pavilion dv6000 won't turn on power button quickplay motherboard faulty problem repair

DV6000 lights turn on, nothing else [Solved/Closed]

Quote:
This sounds ridiculous but I'm not kidding it works for me every time, I have the same issue. HP Pavilion DV6408NR. The problem is due to the nvidia graphics chipset becoming slightly unseated from the mainboard.

Remove the RAM access panel, you will see your ram chips and above these is the wlan controller and directly beside it a small black chip that says Nvidia. This is your graphics chip. We want to leave these COMPLETELY exposed at all times (you might as well get used to just not having the panel on for this fix).

From a cold start (i.e. the computer is completely off and unpowered) boot once, wait about 5-10 seconds. This will allow the motherboard to build up some heat... If you touch your graphics chipset you will notice it's started to warm up. Now go ahead and power the computer down, it's not going to boot on this attempt, but we got the solder warm.

Again power the computer on, and wait a few seconds. This time you should hear your fan magically kick on (assuming the fan is still working, as it is in mine). AFTER, and only after you hear the fan rev up to full speed, begin applying FIRM pressure with your index finger to the gpu (the black chip that says nvidia). Just wait a few seconds and voila, your HP POST screen magically appears.

I've had to do this with this laptop for nearly 2 years now. It never takes more than one to two tries to get it to start up. A word of warning: Do NOT close the screen, you only have about a 5% chance of it actually coming back on when you open it back up.

I'm aware this is a "quick and dirty" fix. If you have the patience and the cash you should just send it in to HP and have them fix it for you. If you have the skill, you should reflow the chip to the motherboard and fix the problem yourself.

If you're like me and you're lazy and broke, this fix will do the trick for the rest of the laptop's lifetime.

Although the DV6000 has major nvidia GPU problems it will normally power on and stay powered on but without video. Since yours will not stay powered on and it started when your AC adpater died I suggest you take the battery out and just power up with the AC adapter. If you see no blue lights and no power on then your new AC adapter is not working and your battery is too low to power up.

Thanks for the thought, but the unit does the same thing with the power supply or the battery. The battery WAS completely discharged but after letting the DV6000 sit overnight plugged in ( I was in a "What Now" mood and just left in on bench) it seems to have charged battery. Either way though Ac adapter Only or Battery only it does the same thing. Hit the On button, blue lights across the top light for a second then go out!

I had the same problem on my old dv6000. I tried all those fixes - none worked for me.

In the end, I replaced the switch ribbon cable, and all works fine now. Cost was about $1 from ebay.

You need to remove the 3 screws under the battery and the 2 back (left and right) corner screws so that you can tilt the speaker and switch housing. Before you do that - remove the 3 keyboard screws (2 underneath the battery compartment. you will need to also open the RAM compartment for the 3rd screw.) The 3 screws have a pic of a keyboard next to each one. If this doesnt make sense - see youtube for tutorials on opening the laptop - its pretty easy to do.

Then replace the ribbon cable connecting the switch to the computer. The slot that the cable plugs into at the switch has a grey clip that you need to click forward slightly (not too much) to release the old cable. After inserting the new cable you need to click the clip back to hold in the new cable. The other side doesnt have a clip - just pull out and push in carefully.

(another temporary option for me was to remove the switch cable and use quickplay button. my laptop also has a remote control with a on/off switch, and both worked when the cable was removed.)
