Question about HP Compaq 6735s Notebook

1 Answer

I have a HP 6735s and was using it today. After about half a hour the screen went black and the laptop powered down. I tried another power cable that I have and also a battery but the laptop constantly shut down while trying to power up. When I was using the laptop I noticed that the power icon did not appear to be charging up.

The laptop maybe overheating.
When the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make surethe vents are clear and dust free. Use a can of compressed air to do this.

Hi. I have hp 6735s laptop and when I move him screen suddenly go black or in rare case white and I need to hold power button to shut down and when I turn him on everything is normal until I move him again...


When you say you move him, do you mean lifting the unit and moving to another location or just moving the lid (changing angle of the lid/lcd)?

If changing the angle of the display gives you black/white screen, you may be having problem with the LCD cable, it might be loose or defective. But if moving the unit to another location gives you the black/white screen, one component of the unit might be loose. Either you need to properly reinsert the memory of the harddrive. If these simple steps will not resolve the issue then you might need to check the whole motherboard including the connection to the LCD.

Hope this helps.

My laptop is hp compaq 6735s when i press power button the fan will roll but my screen is black what can i do?

1) First check the Display to make sure this isn't the problem.

Laptop on shine a flashlight at the LCD screen, and various angles.
Do you see faint images?

Do you have a VGA monitor available? (Also referred to as a CRT. Resembles a small TV)
If so, laptop off plug the VGA monitor into the VGA connector on the Left side of the laptop.
(Typical VGA connector, )

Turn the VGA monitor on, and let it power up. Once the VGA monitor is powered up turn the laptop on.
Is there a display on the VGA monitor?

If not press and hold down on the Fn key, then tap the F4 key.
This action should toggle your display over to an external monitor.

Yes? You have a display on the external (VGA) monitor?

Then you have a problem with the Backlight, or the Inverter.

An LCD screen cannot produce enough light by itself. It needs an additional light source.
A Backlight is used as an additional light source.

A Backlight is a CCFL.
Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.
(Typical size is 3 to 5 inches long, and half the diameter of a No.2 pencil.
A Backlight is located within the metal framework holding the LCD layers together, and is on one edge of those layers. {An LCD screen is composed of layers)

An Inverter is used to provide power from the laptop for the LCD screen, and the Backlight.
90 percent of the time the problem is the Inverter.

An Inverter is a small circuit board located within the Display Assembly. Behind the Bezel of the Display Assembly, and located usually at the bottom of the LCD screen.
(The Bezel is the thin plastic frame that surrounds the LCD screen in the front)

Typical example of an Inverter for an HP Compaq 6735S,

The Display Assembly needs to be removed from the laptop, in order to remove the Bezel, and gain access to the Inverter.
Pictorial guide of how to remove the Display Assembly,

Follow Steps 1 through 7.

This pictorial guide shows how to remove the Bezel. The guide is for replacing a webcam module.
Disregard removing the webcam module, and follow the other steps.

2) If NO display is shown on the external monitor you have a graphic chipset problem.
This requires replacement of the motherboard.

Chip and Chipset are slang terms to mean I.C.
Integrated Circuit.

The graphics chip is mounted to the motherboard with a BGA surface mount. (Ball Grid Array)
Having the chip removed and replaced is more expensive than replacing the motherboard.

Looks like your battery is having a problem. Remove the battery and replace after a couple of hours. If problem remains replace the battery with another to test, if this works, then the problem is with the adapter unit. Get a new one.

HP 6735s screen black out on startup.

The problem is a damage to the MB by excessive heat produced by Nvidia GPU. The only way to fix this permanently is to take out the MB and reflow the GPU with heat. You can find a video on youtube how to do it. You must take out the piece of gel between GPU and cooling unit and replace it with copper bar or penny made prior 1983 - still made out of copper. Also clean the fan. Use heat transfer paste like arctic cool - not a glue, on both sides of the penny. Install win7. Win7 does not use the coprocessor and will help to ran the notebook cooler. Install speedFan 4.40 - free utility to see what the temp is of your GPU and CPU. If you did good job it will stay around 55C. If your HP notebook is still running check the temp. If the GPU is running 80C or more it will melt the connections on the MB and quit working sooner or later.

Have you tried another power cord? If you try another power cord, and it still does the same thing, then I think your laptop is having a power problem. You need to take is to a technician to fix the problem for you.

Best wishes.
