I have a hp dv9000 running Vista that I’m trying to fix for a mate, it seems when I switch it on it gets stuck at the hp screen with all the options. If i leave it there for a couple of minutes it comes up with “no operating system found”
The only options that have any effect is f10 (for the BIOS menu) and ESC for the startup message. (I managed to get the hp recovery up once to do a factory reset but it goT stuck at 10% for hours and never worked again)
start up message looks fine except that System BIOS is shadowed and Video BIOS is shadowed.
I tried doing the hard disk test and it doesn’t run and comes up with “no IDE Device”
I then did a memory test (which ran fine) and the result came up with “#10001 replace memory module”
Does that mean I need to replace the hard drive or the RAM? Or is this a problem that cannot be fixed?
Ive tried the basic stuff like a windows CD and taking the battery out. No effect at all.
Oh and it has PhoenixBIOS 4.0 Release 6.1. BIOS vVersion F.30.
Please if you could give me any clue or direct me to somewhere I could find the answer it would be appreciated!
I got a pavillion dv7 here too and was thinking of swapping the hard drives but unlike desktop computers I don’t know if it’s safe to do so?

I have tried removing and replacing power, removing and replacing the battery, re-seating the memory cards — nothing seems to help.

I replaced the CMOS battery, but that didn’t fix the problem.

i was wondering if i have a pavilion dv5000 hard drive would it fit in a dv9500 ?

It depends on the type of hard drive you have installed in the Pavilion dv5000 notebook.
If this is a SATA hard drive you can fit it into the Pavilion dv9500 laptop.
If your dv5000 has an IDE hard drive, you cannot use it.

I replaced the AC adapter with a new one and swapped out the battery with my daughter’s. She has the same HP laptop as mine. Same problem. The blue ring at the jack lights up but nothing on the front of the laptop or on the screen saying its charging. With the battery fully discharged the laptop won’t boot up either since no voltage is getting to the laptop. I’m thinking I will have to replace the motherboard but was hoping there would be an easier fix like just replacing the jack.

I doubt this is jack related problem. Sounds more like motherboard failure.
Think twice before replacing the motherboard. There are no new motherboards out there. Most likely you’ll get a refurbished one.

My HP Pavillion works just fine except I can’t charge the battery. Changed bricks still no charging. I get the illuminated blue ring around the AC adapter port when I plug it in but the charging light won’t turn on at the front of the laptop and the battery indicator onscreen shows no charging. I’ve heard the AC adapter port is a weakness of the HP laptops. Is this repairable or do I need to swap out the motherboard?

It’s hard to tell what is wrong without testing the laptop with another battery.
Could be bad batter or motherboard failure.
What bricks did you change? The AC adapter? The battery?

I’m working with a smaller Toshiba right now and I sure miss my HP’s 17″ screen.

So turned on the computer today and the DVD drive is not being recognized by the computer again. Looked up under bios and its not listed there either. Options?

It’s hard to tell what’s going on without testing the laptop with another working drive.
Could be one of the following:
1. Bad connection between the drive and motherboard.
2. Failing drive.
3. Motherboard problem.

I would try reseating the drive first and see if it fixes the issue.
