If the fan is spinning when you switch on the laptop and there's no display, this can be a problem with the memory. Try removing it, putting it back and also if you have 2 memory cards try with only one.
Try connecting to a external monitor. If it works on a external monitor, problem is probably with the inverter or LCD flex cable.
Finally I found someone else with my problem, I got a HP pavilion dv6700 with nvidia graphics and windows vista. It worked fine until today when it just wouldnt show me crap on the screen, ive tried searching for it on this forum but all I found was press ctrl+alt+delete and do lotsa stuff... BUT HOW THE H£LL can I do that when I cant see anything and the computer wont even respond to anything else than the power button? The fan is going and all the stuff on my keyboard is lighting up like it should, but the screen is jsut like it was before I turned on the computer. I guess its my graphics card thats against me on this one. Theres obviously no warranty on it and I dont want to buy a new graphic card when I dont even know if thats the problem.
So if anyone could help me I would be forever happy.
Chronology of my terrible horrible no good very bad experience with HP dv2000.
4 months after I purchased it:
1- Overheat to the degree I can't leave it on my lap.
2- The battery died cell after cell until I had no battery at all and need to be hooked up to the power all time.
3- The charger cable got ripped off from the inside.
4- The hard drive got burned making me lose important data.
5- Another hard drive got burned with the same story.
6- The picture started to act funny, maybe because of the VGA is acting up and starting to die slowly.
7- DVD drive laid to rest forever.
8- Finally the VGA died giving me a black screen, and even the BIOS doesn't show up.
One year after purchasing the late HP dv2000, I returned to my three years old couple of Laptops "warriors" Dell inspiron that still love me even after I dropped them for a terrible horrible no good very bad HP dv2000.
I took a promise on my self to NEVER EVER purchase the following products:
5- Western Digital.
The HP DV series laptops and some others have known motherboard issues and if you are lucky and have an affected model they will replace the motherboard free of charge but only HP can tell you if your model is affected by this. If not the laptop board for the DV series runs from 169.00 to 249.00 depending on your model
HP's pop-up window stated that my DV6663US (Vista Ultimate 64) laptop needed a bios update. I foolishly believed them, followed the instructions and installed the update, which destroyed the laptop. The laptop was working, but now nothing works and HP says they aren't responsible because it is out of warranty, but for the price of a new laptop, they will install a new motherboard. WARNING: Do NOT take HP's statements at face value. HP may have needed to destroy my laptop in order to inspire me to buy a new laptop, but it won't be an HP.
For DV2000 Laptop please contact HP - they have a recall going on. They will replace the motherboard for free. I told my friend and he got his done. Believe me on this.
For HP Touchscreen Laptop TX2110 US or similar, if you laptop isnt booting up and your are out of warranty, please call HP sales and Service, dont mention anything about your broken laptop, by HP extended warranty, will cost about $150. Wait for few days and then call Tech support and tell them your laptop went bad recently and have it shipped over to them and they will replace the parts for free because now you are covered in extended warranty.
The trick is to be able to buy extended warranty. It worked for me
ps: I really owed a reply to this forum bcs I was devastated when my laptop broke and now its fixed.
