Compaq 6515b Random Freeze

I have a Compaq 6515b, with Vista Enterprise.

It randomly freezes up about twice a day. There's no telling when it crashes, it's not when I use a specific program, or am doing something specific, but I'm just in the middle of my work and it crashes.

When it goes down, the screen just goes black. The backlight remains on, everything else is kaput. The Wireless button has no effect (doesn't turn on or off), but the mute button goes on and off. Caps Lock and Number Lock have no effect and the indicators do not come on. I have to hold the power button for about 10 seconds to get the machine to shut off. I can be on Skype, and the call will just cut out when it happens, meaning it's a full system crash and not a video issue.

Please assist, or at least throw me some ideas.
Thanks!

 

Could be a million things. Use AV/AS scans, get a can of air and blow out your computer, update all drivers...

 

It's not like that. I built an image on this and deployed 42 of them, all with the same hardware and image. Around 5-10 of them are having this problem (That they've reported) It's not a dust problem or anything like that.

The system logs show nothing, and there's no stop error, even with the Auto-Restart turned off.

 

I just got a Compaq 6515b about 2 weeks ago. It is a brand new laptop running Vista Business 32bit and I am having the exact same problem.

At first I thought it had something to do with the combination of being unplugged and on wireless (the most important feature of a laptop) but after being plugged in and on LAN it happened again about 15 min ago.

It doesn't happen as often as twice a day, but it has happened about 6 times total in the first 2 weeks here. Everything is up to date, all drivers and patches have been applied. There doesn't seem to be any other information about this issue out aside from this thread.

Since you haven't posted anything on this for 4 months, I was hoping you may have found a solution? I'm thinking the solution might be this thing is DOA and I need to get an XPS 1330 from Dell =P

 

I'm Having the exact same problem with a 6515b that we just bought in December. This happens 1 or two times a day and I've already tried replacing the ram.

 

Hi guys,

I have the exact same problem and it really pisses me off. My laptop is a toshiba satellite A210. I tried a lot of things to make these random crashes stop without success (various video drivers, various power managment settings).

One thing I'll soon do is a memory test with http://www.memtest86.com/.

If anyone have a suggestion, plse tell it would be greatly appreciated.

RAM is okay, so the problem must be something else. I realized something important lately. My laptop usually freezes right after or shortly after it comes back from standby mode. Any ideas?

 

Check it out after Vista SP1 released. Might work better!

 

Thanx but actually I have winxp installed on it...

 

It has happened a few times shortly after coming out of sleep or standbye, but it has also crashed in other situations.

One crash was after I unplugged it and switched to WiFi to go into a meeting. Worked fine for awhile in the meeting, and as I was going over action items, it crashed in the same manner it always does. Instant black screen, everything is dead.

I would say it happens more often after sleep/standbye, but it still crashes outside of that function as well.

It is really frustrating.

 

I disabled standby mode on my laptop. I think it solved my problem because it don't freezes anymore... I know this solution does not solve the problem to its source but it's better than nothing...

 

Ok, I solved my problem by updating the computer's bios from 1.3 to 1.5! YAY!

 

Yes, the problem is for sure Standby mode. I put it in Hibernate instead but that is such a pain in the...

Standby is really useful to me, I hope HP comes up with some type of fix for this.

 

Oh nice, can you provide the link to the latest BIOS?

 

Well, my laptop is a toshiba, so the bios is different from the one you will have to use. Mabye you can check on HP site for the newest bios of your model.

 

The latest BIOS is F.07 or something like that. Its from June of last year and is what this laptop is using.

HP Has nothing for me =(
