How to solve overheating problem with HP 6735s

Standard problem with all 6735s laptops... It's not about software or anything like that just a lot of dust... You need to clean it. Open your laptop and clean that dust and you will get a core temp 50 to 60 C max... It worked for me.

This laptop disassemble guide is taken from www.insidemylaptop.com

I'm not responsible for any damage on your laptop.

STEP 1.

Remove the battery.
Remove covers from the hard drive, wireless card and memory.



STEP 2.

Remove one screw securing the DVD drive (red circle) and pull the drive from the notebook.
Remove memory modules (in my laptop I had only one module installed).
Remove the hard drive, you’ll find details instruction on the sticker glued to the hard drive caddy.
Unsnap two antenna cables from the wireless card. Remove two screws securing the wireless card (green circles). Remove the wireless card.



STEP 3.

Remove five screws securing the switch board cover (red circles).
Remove two screws securing the laptop keyboard (green circles).
Remove eleven screws securing the laptop bottom cover (yellow circles).



STEP 4.

Lift up the switch board cover. You can separate the switch board cover from the bottom cover with a piece of soft plastic. I’m using a guitar pick.



Be careful, the switch board cover is attached to the motherboard. Do not pull the cable from the connector yet.



STEP 5.

Lift up the keyboard and place it on the switch board cover so you can access the keyboard cable connector.



The keyboard is connected to the motherboard via a flat ribbon cable. Before you pull the cable and remove the keyboard, you’ll have to unlock the connector.



On the picture below you can see the keyboard connector unlocked. Now you can pull the cable and remove the keyboard.



STEP 6.

After the keyboard has been removed, you can release the switch board cable and remove the cover.



STEP 7.

Remove four screws securing the notebook speakers.
Unplug the speaker cable from the motherboard.
Remove both speakers.



STEP 8.

Release the wireless card antenna cables.
Unplug the webcam cable from the motherboard.
Remove four screws securing the display hinges (red circles) and one screw grounding the video cable (green circle).



STEP 9.

Lift up and remove the display panel assembly.



STEP 10.

Remove two screws securing the top cover assembly.



STEP 11.

Carefully lift up the top cover assembly.



Be careful, the touch pad cable is still attached to the motherboard.Release the touch pad cable and remove the top cover assembly.



STEP 12.

Now we can access the motherboard.

Unplug three cables pointed with arrows.
Remove three screws securing the motherboard.
Lift up and release the RJ11 (modem) jack.



STEP 13.

Start removing the motherboard from the laptop case.



The motherboard has been removed.



STEP 14.

Finally, you can access and clean the cooling fan.
Simply remove one screw securing the cooling fan to the laptop base and clean it.



Clean all dust from here and follow this steps backward so you get all parts together.

HP 6735s - Snow Leopard 10.6.1-10.6.2 Intel AMD made by Hazard

Everything is working except graphics QE/Ci but i get native resolution.

Step 1: What version to use?

I tried Kalyway, iAtkos 4a, iAtkos 7, iPC, and only one worked for me is Hazard's Snow Leopard with updates 10.6.1 and 10.6.2 for Intel and AMD. Search google to find it.

Step 2: Preparing for installation:

I tried with all boot commands -v, -s, -f, -x, platform=X86PC, speedstepkernel, busratio=20, cpus=1 and others if there is some i didn't used. Things you'll need:

1. Boot132: Burn it on cd with Magic iso or other software
2. Snow Leopard by Hazard iso file: Burn iso to DVD but don't use DVD-RW
3. IOATAFamily.kext : Search it on google
4. USB Flash: Any size

Step 3: Installation:

Put cd with boot132 in dvd and restart computer, then press ESC key to get to BIOS setup screen. Press F10 and click on system configuration then i think it's device configuration and set your drives to IDE and in boot settings put yout dvd drive frist in the list. Save settings and exit. When you get boot:>  press enter and wait for image like this:



Then eject your cd with boot132 and insert dvd with hazards snow leopard wait for 15 sec and hit enter, then you get again on boot page, just hit enter. Now wait for dvd to load.

When you get to welcome screen you need to agree with some licences. After that go to tools - disk utilities. Select your hdd and go to erase:

Volume Format: Mac OS Extended (Journaled)

Name: (put smaller name without spaces like mac or something like that)



Hit Erase (This will delete all your data on hdd). Now close disk utilities and in select destination window select your hdd and hit continue.



Before you hit install click on Customize button and select this packages:

Click ok and then install. Now wait for install to finish. When its done you need to reboot your computer hit reboot (in some cases it just stuck on that screen so you need to press and hold power button to turn it off than press it again and eject your dvd).






Step 4: Post Installation

For native resolution you need to install RadeonHD
Open terminal from applications -> tools and type this:

cd downloads/RadeonHD.kext/Contents/

sudo nano Info.plist

enter your pass and hit enter. FInd line with "EnableHardWareCursor" and under it set value from true to false. Press ctrl+x and it should ask you to save edited file. Press Y and hit enter. Close terminal and go to downloads select your radeonHD.kext and drop it on KextUtility, enter your pass and wait for it to finish. Now you have native resolution.

To enable wireless:

Download bcm43xx_enabler.sh

Open terminal:

cd downloads
sudo ./bcm43xx_enabler.sh

press enter, when its finish close terminal and restart computer.

Step 5: Done :)

That's it. Sound is little fuzzy and i didn't found a way to fix it.
