Welcome to FixYa!
Im very sorry to hear that, please follow these simple steps for you to be able to isolate the exact problem.
1. Removed the battery.
2. Connect the laptop directly to the power outlet without using the battery just for the meantime.
3. Turn on the laptop. If the laptop is able to power on, that means that the AC adapter is working fine as well as the DC port. If the laptop is not able to turn on, it maybe the AC adapter itself or the DC port.
4. Try to use another AC adapter if possible, make sure that that AC adapter is working fine. If the laptop is still not turning on, the problem is with the DC port itself. In that case, you will need to replaced the Motherboard itself.
Hope this will help...Thank you for using Fixya...
You can watch for a replacement motherboard on ebay - often these can be had fairly inexpensively - HOWEVER- you MUST have an EXACT and DIRECT replacement for it to work. While there is some interoperability amongst HP/Compaq motherboards within a particualr model number, you need to be SURE that what you buy will work with what you have. CHECK PART NUMBERS CAREFULLY.
Changing out the motherboard is something best done by a computer technician but it can be done if you are patient and have decent mechanical skills. Don't forget to use thermal grease correctly on the motherboard and video heatsinks or you will burn the unit up.
If you have the internet, goto my computer and right click, then goto properties, enter device manager, goto sound,video and game controllers right click on the exclamation mark or your audio driver and click update driver, use the internet option to download the driver, it takes a few minutes so be patient. once done reboot the mechine.
Hi there. Boot the laptop into safe mode by restarting the PC and hitting F8 as it starts, then try to install the audio driver again. If this method does not work please post back as there are other methods to install the drivers.
There is a specific known issue with the Bios on certain model laptops that once the Bios has failed the laptop will not boot. It happened with my wifes 6000. I searched for a week and then finally found a very obscure article about it. I called HP/Compaq and gave them the symptoms and what I had already done (reseated the memory, hard drive and verified that the AC Adapter was good) Finally they acknowledged that her SN laptop had the known issue and sent me a box to ship it to them for motherboard replacement. The laptop was 4 months out of warranty so if I hadn't found this it would have been junk. Good Luck.
