overheating, no display

[Noxqses092081]

Hello,

My name is Lee i am a master computer repair technician.

for all you owners that currently have a laptop in the DV series i am posting a blog about your no displaying video options and overheating issues and easily fixing them so you don't feel like you wasted a ton of money.

Laptop turns on  but displays no video right?

laptop constantly overheats rights?

OK, first step is to completely breakdown your laptop to just the motherboard or ( MoBo) itself.  that means unplug any wires and so forth all ribbons must be removed!

second step is to remove the cpu or processor  and remove any and every bit of stickers or plasticity  that covers components on your mobo.

3rd step   preheat your  oven to 285 degrees celsius

4th step use tin foil to cover transistors or plastic parts that may melt...

5th step  find a pan of some sort  that your mobo will easily fit into

6th step  place your mobo into the pan and place into oven with your chipsets facing upwards ( very important!!)

7th step   make sure you time your oven if you have a timer thast probably more efficient    for 15 minutes..

8th step  very critical!!!   when you are down to about 2 minutes left  place your oven on broil HI setting..

9th step  when timer goes off  turn oven off and vent the oven by opening the door halfway  with a fan running of some sort..

10th and final step.     after 30 minutes take the motherboard out the oven  and put back together   then WAL LAA!!  your laptop is running perfect......  make sure the vents on the bottom cover of the laptop are clean from all particles and dust  as well as the heatsink and fan..   

your welcome and havea  nice day 🙂

seriously? How does this fix anything. I'm ready to put that POS in the oven on broil for 45 minutes because that''s all its good for.

it reflows the solder underneath the chipsets back into place..  ive reapired over a thousand laptops this way.. i have not had any unsuccsessful jobs..  its a fixer for life 🙂

I am thinking of sending my dv9000 in to get it reflowed.  I am nervous about putting it in my gas oven.  I have already bought a new lcd screen and inverter and they want $85 you reflow the gpu.

You said you have done 1000 of these and it works every time.  Do you shim the gpu after you reflow it or do you just put it back together.

Can you be more specific on the procedure.  I have watched all the videos on youtube.  anything to add?

Thanks, Mike

just use 99.9% Artic silver thermal compound on your chipsets, gpu,and cpu..   i personally dont use copper shims only because ive never had to... and as far as using a gas oven..   i highly recommend you dont.. but that will be at your discretion.. you are more prone to warping your mobo beyong repair using a gas based oven...  and also if you decide to send it in to get reflowed  make sure you tell whoever is gonna do it  to remove all stickers and what not  that keeps unwanted heat inside your laptop..    hope this helps

thanks for your advice but mine displays on external monitor but with some blue vertical lines is it the gpu or something else?

How long a time if the owen max is 250°C and how do you cover parts with tin foil if put in an owen? I have a 15-p059no and Speccy says teh processor is going at 113°C which is way over highest acceptable 79°C - updating drivers don't seem to do anything dramatic after changing the system from Windows 8 to Windows 7. I've tried reflow using a heathblower already and renewing silicons with a product called "arctic silver".

Answers found on the processor heating problem itself, but not on converting the "baking" time with an "underheating" owen... 🙂 

HP support says: No support for Windows 7 (even though the product page introduces Windows 7 drivers + other swsetup -files for the 15-p059no

Moreover they say that the way to solve this would be to get the recovery DVD since none has been made. This is to get the Windows 8.1 Home Edition back onto a new hdd. I wonder how this is going to affect the processor heating problem, but I'll get back once more with results if this solution is to be the chosen one and especially if it helps (for some reason - I could understand a BIOS update + firmware update could do something and done already, but a change of a Windows version... remains to be seen).
