Question about HP Touchsmart 300-1000 Series,amd Athlon Ii X2 235e 2700mhz,ram 4096mb,640gb
When I turn the computer on for a second it acts like it wants to start but then the fan kicks on high and stays like that until turned off. I figure it may be a graphics chip problem and am thinking of buying a new motherboard. Do you think it'll fix the problem? the drive works fine.
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

SOURCE: HP ZV6000 Fan Making Noise
I had a similar problem on my zv6000, but I've tracked it down to the fan in the middle (not the one above the CPU with the heatsink).
For anyone else that doesn't feel like taking your laptop apart twice (once to get the part number and twice to put the new fan in after you get it online, etc.), the fan is a Sunon Maglev GC 056015VH-A. HP doesn't carry them in the parts store anymore, but I ordered mine online from an independent retailer.

HOW TO FIX YOUR DV6000/DV9000/DV2000
All the Problems described are Graphics Related..
Faulty Nvidia Chip..Both Intel And AMD Based Motherboards..Though More Common on the AMD..
The symptoms of the Laptop Powering on and Shutting Off Repeatedly..Or.. Powering On and Having No Video...Or... Power Strip Lights Up, Beeps,Shuts Down...Or..No Power At All...Or.. Intermittant Loss Of Wireless/Video Goes In And Out/Touchpad Slows and Freezes..
To Fix this issue, You will need to Reflow The Graphics Chip.
I will Explain In Full Detail As To The Correct Method Below....
HP DV6000/DV2000/DV9000 Compaq v2000 Video Chip Reflow Instructions
First Step Is Complete Disassembly Of All Parts And Components..
Remove RAM, Remove CPU, Of Course Remove Heatsink and Fan assembly.
Next Step is Insulating the Motherboard... You need to Protect The CPU area, The RAM area, Cover any plastic Plug ports.
Try to leave 1/4 inch area around the edge of the chip free of insulation.
To Insulate the Board.. I use thick pieces of Tin/Aluminum, you can fold up some aluminum foil (tin foil) About 4 folds thickness....
Now that you have your Motherboard Insulated... Make Sure There's Nothing Flamable Or Burnable Below the Motherboard... it will get quite hot underneath.
You will need a Heat Gun.. You can get one of these at your Local Home Improvement Store, they cost about $15 - $30.. You Will Use ONLY the LOW Heat Setting... I REPEAT..... USE ONLY THE LOW HEAT SETTING ....
Next You Will Need Some Coins.. Yes Coins..
8 Quarters and 2 Nickels... Put the 2 Nickels On the Bottom and Stack Quarters On Top...
Place The Stack Of 2 Nickels And 8 Quarters On Top Of The Graphics Chip...
The Reason for using the Coins: Using the coins serves a few purposes...
1) It Helps Transfers the heat Into The Chip More Evenly/Slowly
2) It Helps Hold The Heat Longer/Then Helps To Cool Slower
3) It Gives The Correct Amount Of Weight That Is Needed To Press The Chip
A Thing To Look Out For...
Hewlett Packard is nutorious for using the RED epoxy around the edge of the Graphics chip.. this epoxy is used to help secure the chip to the motherboard...
This is a process that is Hand Done at the Factory.. And Some Boards Will Have Only A Little Amount of this, Some Will Have Alot of it...And Some are Only Done On The Corner Edges....
If There Is Alot of This On Your Chip, You Might End Up Needing To Carefully (REAL CAREFULLY) Remove as much of this epoxy as able to....You can use a Razor Blade To Lightly Scrape This Off... DO NOT MISS AND SCRATCH THE MOTHERBOARD!!! Go SLOW...
Now Comes The Heating Of The Chip...
Start With The Heat Gun About 6 Inches Away From The Top Of The Quarter Stack..You want to be holding the gun at a 45% angle.. Aim the heat at the Edge of the chip, You Will Start Rotating Around the Chip- around the outer edge of the chip...then use tighter circles concentrating on the quarter stack, then after about 30-40 seconds, slowly move closer to the chip...
Never Move the Heat Gun Closer than the Top Of Your Coin Stack...Then Pull It Back And Slowly Repeat.. The Chip Needs To Get Hot Enough To Re-Melt The Solder Balls On The Underside Of The Graphics Chip Back Down To The Contact Pads On the Motherboard.. and this takes Quite Alot of heating to Do.... You Must Not OVERHEAT the CHip... It Is Best To Underheat it and have to Redo.. than to overheat.. It will cause the solder to break down and even crack/split.. causing failure forever...
This process will take about 3 minutes total.. Once you shut off the Heat Gun.. Leave The Stack of Coins On The Chip And Let Sit For Another 5 minutes..
Now Remove The Coins(carefull they might still be hot)
Remove All Insulation.. Reinstall RAM, CPU, Heatsink and FAN Assembly (and Of Course Thermal Pads or Paste.. Note:. If Paste Is Used.. It Must Be Silver Paste...
Now You Can Connect The Power Button Strip/ Video Cable And The DC Jack Cable.... And Plug In AC adapter .. You're Now Ready To Test For Solid Power and Video....
Upon Sucessful Chip Reflow/Rebake.... You Need To Go To The HP Website..( www.hp.com )..Click on SUPPORT AND DRIVERS, then select...DOWNLOAD DRIVERS AND SOFTWARE....Then either click the box to Auto-Detect System, Or Enter Your Make/Model Info, Once At The Page With All Of Your Drivers.... Choose The BIOS UPDATE Driver..
Choose The Newest Driver And Download/Install It... It Will Reboot The Laptop And Upon Rebooting, Your Fan Will Spin Faster And More Often Due To A Thermal Controller Update In The BIOS Update...

that means your laptop has no power so your battery is dead which would explain why it shut down on you, and that means its not charging so it would either be the adapter or the port on your laptop

You might have a cooling problem due to a fan malfunction. It is not clear whether it's the power supply fan or the CPU fan; in the latter case you might also have a thermal coupling problem. The symptoms you describe certainly seem to point to such.
My advice would be to replace the fan (or the whole power supply; you might also want to purchase a "Silent Power" unit for quieter computing). If it's the CPU fan and you are comfortable with, or know anyone comfortable with a bit of PC servicing, you might want to also unmount the heat sink from the CPU and replace the thermal paste between CPU and heatsink. Clean the heat dissipator (the black metal grille over the heatsink) with hot water and a bit of soap and dry thoroughly, or wipe it energically with a dust brush, before mounting the new fan on it.
