HI EVERYONE, I´M A COMPUTER TECHINICIAN AND I HAVE EXACTLY THE SAME PROBLEM WITH ALL LAPTOPS FROM DV SERIES NO MATTER WHAT MODEL IT IS, NWER OR OLDER, ALL OF THEM HAVE THE SAME PROBLEMS, NORMALLY IT APPEARS ON AMD CPU MORE THAN INTEL CPU, AT WORK I HAVE 2 LAPTOPS FOR REPAIR, A DV6140US AND A DV6408NR, BOTH PRESENTING EXACTLY SAME FAN OR TEMPERATURE PROBLEM, ALL LIGHTS ON FOR A FEW SECONDS, FAN WORKIN, DVD TRYING TO READ, AND SCREEN BLANK OR BLACK, NO IMAGE SHOWING, THEN THE LAPTOP RESET AND START AGAIN WITHOUT SCREEN SHOW. 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. If you have the skill, you should reflow the chip to the motherboard and fix the problem yourself. If you have the patience and the cash you should just send it in to HP and have them fix it for you. I'm aware this is a 'quick and dirty' fix. 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. It never takes more than one to two tries to get it to start up. I've had to do this with this laptop for nearly 2 years now. Just wait a few seconds and voila, your HP POST screen magically appears. 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). This time you should hear your fan magically kick on (assuming the fan is still working, as it is in mine).

Now go ahead and power the computer down, it's not going to boot on this attempt, but we got the solder warm.Īgain power the computer on, and wait a few seconds. If you touch your graphics chipset you will notice it's started to warm up.

This will allow the motherboard to build up some heat. the computer is completely off and unpowered) boot once, wait about 5-10 seconds. 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).įrom a cold start (i.e. 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. The problem is due to the nvidia graphics chipset becoming slightly unseated from the mainboard. This sounds ridiculous but I'm not kidding it works for me every time, I have the same issue.

Hp dv6 wont turn on
