Hi,

Welcome to Fixya. On your description it seems that there is a power on the laptop however we cant determine yet if the problem is the hard drive. We can so some steps to check if the problem is the hard drive or other components of the computer.

1. Can you remove the battery of the computer for 2 minutes after that connect it and turn it on. We'll try to power drain the system and see if it will work.

2. Is it possible for you to use an external monitor to check if the problem is the LCD. Press FN + F4 to toggle the display and see if the problem is with the LCD.

If NO display is shown on the external monitor you have a graphic chipset problem.
This requires replacement of the motherboard.
If the problem is with the hard disk you will still be able to see the POST screen.

If you wont be able to see this on an external monitor than the problem is the Graphic Chipset. but if you see it then the problem is the LCD of the laptop.

If you have questions please let me know. Thanks for using Fixya

Hi good morning, my hp 6735s doesnt display anything when I power it on. it flashes a quick brief light on the screen and keep blinking an orange light thereafter the caplock (blue) light comes on and...


Possible that PC is hanging up as there is fault on the OS ( operating system) or a virus in the OS. Also it is possible that the back up( CMOS) has low voltage or the memory card is a suspect. In this case you need to check the voltage and also try and swap a memory card. If not the OS is a suspect.

It is also possible that the mother board is faulty but can be confirmed only after you ensure that the memory and power supply is good.

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...


Hi,

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.

I am an owner of an HP Compaq 6735s Notebook PC. I have experienced the notebook failure. I am unable to start the computer at all. It just happened when I tried to restart it. I have noticed the...


my daughters hp 6735s had the fan running all the time issue, having got fed up with this I decided to try to fix it. I downloaded the service manual from the hp website and dismanteld the laptop to remove the motherboard. The fan defuser had some dust but not much, so I removed the heatsink that covers the cpu and gpu. I noticed the cpu did have thermal compound that was in contact with the heatsink, however the gpu had compound on the chip but nothing touching the heatsink. I cleaned the heatsink, cpu and gpu with degreaser, then applied new silver themal compound from maplin. I made sure i also applied a thin coating to the heatsink. I refitted the heatsink and reassembled the laptop. I powered on the laptop and instantly noticed the laptop fan running at half speed which it should do, I installed a program from a dvd and left the laptop running and so far so good. If we had left this any longer I suspect the solder under the gpu would have become molten and then we could have had another issue which maybe we could not have fixed. I hope this helps you if you have similar issues.

First you need to determine how many blinks you are getting when you try to power on the laptop.
Check the blinking codes below and reason behind that for HP Compaq laptops

Blink: 1 - Caps Lock/Num Lock - CPU CPU not functional

Your battery is critically low. Didnt you recharge your battery? Try turning it on with the external power source connected.

HP Compaq 6735s battery light orange blinking


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.

If you use it from the power cable does it work better? There is a known issue with the 6735s and power management settings from battery.
