hi, wonder if any one can help i m havin difficulty startin up my hp pavillion dv 9000 laptop ...the battery is fully charged and also i have had problems with it over heatin and turnin it self off but i thought i cured this by puttin a hover to the grill where the cpu fan is and suckin out a load of dust cloth fibres etc... ...but when i turn it on the light cum on for a second the fan starts up and turns it self off then is idle for a sec and tries to start up again and repeats the process . i ve took the battery out and power cable to stop it tryin to repeatingly start then put back in and while turnin on pressed esc and ctrl on the key board and then the laptop can start properly and i can get the laptop to work ...wondered if there was any one out there who help ?? any explanations or suggestion would be most welcome ..

So it does start by you pressing a few keys?
Have you checked to see if the bios is still configured correctly?sigpic

Do you get to load windows? Can you see the post menu? You enter bios by pressing the correct key as the bios posts (del-esc-f2), this should be displayed, usually press - to enter setup.
Select boot sequence and select the hdd.sigpic

Need to know how exactly/why your able to boot by pressing keys before anything else. My guess is bios has been resetsigpic

I don't know why esc and ctrl made it start, but from your symptoms it sounds like the common hp fault of knackered motherboard

The fact you took an hoover to it could be enough to damage the motherboard. To clean out dust from laptops/pcs you should use cans of compressed air, avail from most pc shops. I get mine from asda for ?3.
But the overheating could have damaged something alsoCode:http://www.eurogamer.net/forum_thread_posts.php?thread_id=112653
I want to know exactly whats happening? DOes the BIOS post messages? Does windows try to start then freeze, reboot? Do you get a BSOD? (bluescreen of death)
The above faults have differant cures.sigpic

bigfella dont waste your time M8 to start it because it will not unless if is fixed properly, I do appreciate all advices given in your thread I doupt it any of them will work.
Here is the reason all following hp models
TX1000,
DV6000
DV2000,
DV9000
Has faulty Nvedia chip. OK they are working fine when they are new but after some time Nvedia chip develop a fault because over heated.
Symtom of the Nvedia chip problem is.
1) Laptop all blue lights on power-board are on you hear the fan starting for a second or 2 and stops nothing happens.
2) All lights are on and nothing happens. Black LCD screen.
3) If laptop starts all you see is multi colour lines on the LCD screen or one side with wide colour lines in other half black.
All you need is either the chip to be reworked or re-flow there are 3 ways how to do this job.
Manually by the small gas torch, hot air or (IRDA) infrared solder machine.
My advice to you is don't do any of the 3 mentioned methods if you don't know how having said that it can be done if you do some googling or visit Youtube to get some info if you would like to fix it your self. I have fix it quite few of them buy using IRDA soldering machine.
Now if you decided that you gona do it with gas torch or hot air rework station you need to disassemble laptop to the motherboard is out of the casing, again you will need hp dv6000 service manual as there are so many hiding screws and tricky cable to be disconnected from motherboard.
I wish you all luck to fix your hp.
