How to repair a laptop that has lost its
wireless network adapter (WiFi)
and/or has blank screen with no display?
In this case, HP Pavilion DV6000 Series, it is possible
to heat a particular faulty chip on the motherboard
to make it re-solder itself. Keep in mind though,
this may or may not work. This fix might not be permanent.
It just buys some more time for the old, ailing hardware.
Do this at your own risk. I am not responsible for
any damage or monetary loss.
You might end up having a permanently broken piece of hardware
or even damage yourself or surrounding property!
If you are unsure of your skills or if you don't have enough
experience in (computer) hardware, I do not recommend you to
Always read/watch/listen the whole instructions first
before you grab a tool and attack the thingamajig.
I strongly recommend that you view this video first:

in the video that are not represented on this document.

HardForum - Dead video card resurrected
(opens in a new tab/window). There are several authors
telling about their experiences with the heat/oven trick.
Thanks for every author for spreading their experiences
and information. I would not have tried this by myself without
your successful examples.
About disassembling, ovening and assembling
I won't be describing every phase and detail or tool.
You must know which tools you need to have and how to handle
the easily-breaking bits.
Unscrew and remember which screw belongs to where.
Little cables and latches can break very easily,
so be extra careful.
I used q-tips and isopropyl alcohol to clean up
chips before applying thermal paste. They better be
clean and shiny for optimal thermal conduction.
I pre-heated the standard oven (no digital display)
to about 190 °C degrees. When it had reached the target
temperature, I put the foil-covered motherboard in.
The motherboard was in the oven for 7 minutes, exactly.
The cooldown time was one hour, just to be sure.
The image links open in this same tab/window.
The images should be in chronological order.
Hello, you familiar HP logo!
What a beauty for an old HP laptop?
The three front power / hard drive leds work just fine.
The wireless network adapter light is orange.
The wireless network adapter light stays orange.
It should turn to blue.
The wireless network adapter is not present
in the Windows XP Media Center Edition Device Manager.
Okay, you HP Pavilion dv6111eu...
Prepare to be ovened, babe!

before touching anything.
Removing the battery and other easy stuff first.
Need to remember which screw belongs to which hole...
Lifting off the media key bar.
These little and fragile connectors bug me.
A "remember the order of things" picture.
Yes, your teeth look just fine, Mr. Cable.
Yours too, Mrs. Bent Nearby Cable.
Off goes the keyboard.
Off goes the keyboard cable, too.
That keyboard cable bends funny.
I should remember this view and unplug those cables.
Not again these tiny and fragile cables and latches!
Notice the opened latch.
Time to unplug the wireless network adapter and its
Those two orange-circled screws must be removed.
They hold the motherboard. The screws are already
removed in this picture.
Why, oh why so many little cables and latches?
Please give us easier connectors!
Time to pull off the optical DVD drive.
A little screw on the back side
must be un-screwed first.
Lots of things removed from the casing.
Carefully lift up the display connector.
Had to press that little side lever (?)
with a screwdriver.
The display is detached
and so are the WiFi antenna wires.
Another "remember this view" picture.
Finally accessing the motherboard.
Removed the PC card slot... device.
Detached PC card slot device, seen close.
Pulled off the motherboard front audio panel connector
using the shaft of a screwdriver.
Pulled off two more power connectors.
Can be tricky.
The motherboard is now separated from its casing.
Remember the order of things on the motherboard.
Carefully remove all that is removable.
More carefully remove all that is removable.
The motherboard is now naked enough. Front.
The motherboard is now naked enough. Back.
Prepare the baking tray.
These foil feet will be enough to keep the motherboard
away enough from the hot baking tray.
Just to be sure - cover everything else with foil, too.
Other parts might not stand the heat.
The foil covers everything else except
the Nvidia GPU chip that needs heat.
No nearby weak or plastic components near the opening.
The covered motherboard is firmly standing on
the foil feet.
No unwanted contact with the tray.
Should this picture have the caption
"Burn, baby, burn!"?
What does the chip look like
right after the ovening?
Nvidia GPU chip looks just fine. It is not burnt,
it just reflects the yellowish light above.
In the meantime, it's good to clean the CPU.
Also cleaned up the fan and contact surfaces.
I took away the silly blue thermal pad (Nvidia GPU).
A piece of copper (10 * 10 * 2 mm)
will be much better thermal conductor.
The motherboard has cooled off.
The motherboard appears to be in good condition.
Do I remember how to put back all this?
It was wise to took photos with the digital camera.
One can't remember everything.
Checking that the heated chip has no cracks
or other damage.
Both GPU and CPU are cleaned and ready
for the new thermal paste old and cooler.
Remember to lock that CPU tight enough!
The trusty old Arctic Silver 5 should
be just fine (thermal paste).
Checking that the GPU gets proper contact
with the custom piece of copper and thermal paste.
Good enough, but not as good as possible.
The same picture without flash.
I hope that the CPU gets proper contact, too.
It was worth of the time! The wireless network adapter
is detected and usable again.
The WiFi LED light is blue! And the machine can connect
to the WLAN again.
Yep, Windows XP Device Manager now sees the wireless
network adapter as it should. Hello again,
Still working after a couple of restarts.
Time to install software updates
to get rid of security bugs.
The machine did not start at first after assembling.
It just flashed its blue LED lights and then turned off.
I thought it was broken but after a careful inspection
I found out that the CPU was not locked tight enough in its socket
(that round lock screw). The proper locking made it work
again like a charm.
The CPU runs now about 10 °C cooler than earlier.
The GPU runs now about 10 - 30 °C cooler than earlier
and that's very nice! That piece of copper really does it job
better than the original thermal pad.
Hopefully that old laptop will still work
for years to come.
That is all.
Greetings and thanks
And the greetings goes to...
- My wife
- for checking all the pictures
appearing in this document
- for borrowing the laptop
for an undetermined time
- for providing the piece of copper
Update (2012-03-19): The first blackout
After a year and a half, the oven-repaired laptop
hanged up while running Windows. The display just stayed black
and the machine kept restarting itself.
There had been a couple of occasional hangups earlier,
but the "remove battery and power cord for 30 seconds" helped.
I ovened the motherboard and got it to boot normally.
The nasty thing was that the WLAN adapter was missing.
Then I ovened the little WLAN adapter card alone, but it did not help.
The machine seems to be working well otherwise again, but the original
problem is back - there is no wireless network and the WiFi LED
Yet another oven session for the motherboard could do something,
but it could also break it for good. With brand new Windows 8 tablets
looming in the horizon, it could be the time for the old HP Pavilion
dv6111eu with Windows XP to be recycled.
Update (2011-09-30): What's up? It's been a year!
It's been over a year since the oven trick was performed.
The machine is still working well! There have not been any
issues with WLAN (Wi-Fi) or other components.
One could say that it was worth investing so much time and
effort to buy at least one more year of lifetime
for the old laptop computer.
A certain Tomato Seller sent me some nice feedback
this month (September 2011) and hinted that at least some
hot-running laptops could use some extra holes in the bottom
for better ventilation. In this case, HP Pavilion dv6111eu
seems to have lots of holes already. However, it does run hot.
Computers and other consumer electronics devices
generally don't like heat, moisture or dust. So a vacuum cleaner
is a nice thing to own and utilize.
