HP laptop won't get past the BIOS / POST screen

by Ck87.JF / May 14, 2010 11:30 AM PDT

The laptop is an HP Pavilion dv5t-1000.
It has 4GB of RAM, an Intel Core 2 Duo processor, and I think 320 GB hard drive.

The product number is kq574av.

I can set the BIOS settings, I can select the drive to boot from (CD or HDD), but when it tries to boot, it just shows a black screen perpetually.

I've tried swapping HDD & DVD drives as well as RAM from a good computer, all to no avail.

Any other suggestions for testing and figuring out what is going on with the computer?

For a test.

Try no hard drive. Just the DVDRW. Place your working Ubuntu LiveCD (see google) in there and try to boot the LiveCD. I must decline from duplicating what the Ubuntu LiveCD is and how we use that but it's a test I use to see what to try next.

Remember to unplug ALL USB devices as some can cause this issue.

Yes, that's the disc I was attempting to boot from, Ubuntu 10.04
Out of curiosity, why can you not give any additional information? It's free, both in cost & in licensing, I don't see a need to hide any information about it.

Anyway, I tried what you suggested, and when it tried to boot from the hard drive, it complained that one was not present, and when I told it to boot from the optical drive, it did the same thing as before.

I decided maybe resetting the BIOS would help, so I removed both the big battery & the little button-cell battery, then pressed power to release any power ... after that I put both back in, turned it on, and pressed F9 to get to the drive boot screen. Usually it showed Hard drive, DVD drive, network boot, etc. This time it showed four hard drive options, and none other.

Also, there are no USB devices or flash cards (such as SD) inserted.

Thanks for the idea, though it didn't work. Any other ideas?

But I type in all my replies. If I were to type in any instructions I would duplicate "the web pages" about Ubuntu. If this is unacceptable please tell me and I'll remove my first reply and not bother you again.

I realize you type all your replies.
I realize that you are a moderator & that you post many replies.
But perhaps in the space of time it took to write "I won't mention what Ubuntu is or how it helps," you could have mentioned it's a free Linux distribution that by running it, it will test whether the computer can boot from the DVD drive.

Anyway, I'm sorry you found offense in my prior reply, I meant none by it, nor do I here.

I do appreciate your suggestion, as it was a good thought, and gained one small bit of knowledge (about the PC complaining when the HDD is removed).

Is there anything further you can suggest in discovering the problem with this computer?

Off track I fear.

Since the test failed and it appears I've offended you I have now unsubscribed. This is all volunteer and at times when I'm not writing long enough replies or telling all by letting members do some research on their own a few find that unacceptable.

Sadly it looks like the motherboard has an issue. Get a price for that.
