HP laptop error(s)?
Sys Specs:
Windows XP professional Integrated Video card 128meg dedicated 128meg shared Radeon Express. two 1gig sticks of corsair PC2700 SODIMM ram HP Broadcom 54g WAN NIC AMD Athlon 64 CPU mobo EKW70 02 Hitachi HD USB/touchpad mouse keyboard is standard PK13zz77000 rev 00 If I am forgetting anything feel free to ask. I recently replaced my mobo in my HP ZV6000 laptop and upgraded the ram to 2gigs with two pc2700 corsair ram sticks. All went well powered up ran WOW for ~8 hours yesterday. I shut it down had dinner watched some TV went to sleep woke up this morning and now I get many different errors or no errors and it freezes on me. The errors I get are either 4 short beeps (system timer failure)? I had some strange set of beeps that would not fit into any classifaction that I have seen while looking around for beep codes I believe it is a AMI BIOS but not 100% sure. About 50% of the time it boots into windows just fine I load up into wow or firefox and in about roughly two minutes it freezes mouse stopps moving and sound stops. This happens even if I do nothing and just let it run. I have reseated the ram and WAN NIC although it seemed unlikely. I made it into BIOS and reset the defaults. I checked the CMOS battery with my DMM and got 2.98V Even reset CMOS by removing the battery and unplugging it from the wall and holding the power button down. My next thing to check is the heat sink compound on the CPU wiped the old stuff off and radio shack opens in 10mins but if anyone has another idea I might try I would appreciate it. I know its a long post thanks for reading! |

It seems that putting some new heat sink compound helped fix the problem although I have never heard of it going bad or anything like that anyone else ever heard of something similar? (running WOW atm so responces may be delayed :P hafta get my fix yea know?)

Ok now it started doing the same thing again...I really am at a loss now IF anyone has had something similar happen I'll be checking back between troubleshooting this comp.

Fans still run does not get very hot but I keep getting these 4 beeps but on occasion it will work this is confusing me quite a bit at this point it will display the spalsh screen but won't let me look at the BIOS now I could try disassembling it again and rehooking it all up but thats a bit much to do every time I want to use the computer. Gonna give it a shot on firing it up again...

Posting the bios got into it this time around:
PhoenixBIOS sys board ID 3985 2ghz processor 2048 sys mem bios version F.08 KBC version 42.24 gonna see if I can get a recording of the beeps for yea.... ftp://76.183.135.172/errorbeep.wav And BTW stop trying to get into my admin account I do watch who trys to access what and I do have your IP logged just an FYI. You can use the username Anonymous to login and dl the wav file. Last edited by Dsopala; September 3rd, 2007 at 06:40 AM. Reason: added link to error beep sound file. |

I am really confused now.... Reseated the CPU in the laptop booted it up loaded WOW first thing logged in and it runs. No problems I am afraid to try anything else but what in the world is going on with this computer? I have to run a game or it freezes and dies? Odd but ok I can do that but that still leaves me wondering why do I need to reseat the CPU to get it to run correctly I mean what is really changing between lift arm remove reinsert lower arm put heatsink back on reassemble and boot? Nothing is loose when I open the case nothing is loose when I close the case someone out there must have some strange idea festering in their head about whats going on and at this point I would love to hear any reason for this crazy stuff to be happening. Do I need to replace the CPU since thats what seems to be causing this or is it something on the new mobo?

It could have been a weak connection with a pin, perhaps a few, with the CPU and the socket. I suggest you give it a run through though.

We'll see if this fixed it for the moment thing are running smoothly running a scandisk on reboot as well fingers crossed.
update: Still running good and its even running without another program in the background. This was probably one of the most odd glitches I have ever had I can't say if it was a loose pin like PostCode said or if it was something else that took me multiple trys on reassembly to fix. If it still works in the morning I will post one more update and that will be it thanks to those of you who posted and tried to help troubleshoot.

hi
It's been a while, but I have seen bonded heatsink compound weaken so much that the heatsink dropped off the Graphics chip. This is a laptop, and the IGP should have some cooling as well. You may want to look for one of those Laptop Cooling pads I say posted yesterday. |

As far as I know its not a heat related issue but thats a good bit of info for me to keep in mind thanks jtdoom. This compound is so strong it pulls my cpu out with the heatsink and I have to slide it off the heatsink to reseat it lol.
So it's doing it again froze for no reason after a reboot forced by updates made it into windows and while I was cleaning the desk off it locked up. Funny thing is I got no beeps when I rebooted but from previous attempts I reseated the CPU and it started working again. So it must be the CPU but will a new one fix this problem or will I be in the same spot looking at maybe using a dremel to give me fast access to the CPU so I can reseat it when ever I want to use the laptop? Can anyone give me some advice at this point? |

hi
I would not use a dremel. I think there is a loose connection somewhere, and it is not the CPU socket. When you physically touch or move the lapper, it can reconnect and be good to boot (getting to it to reseat the CPU could reconnect the broken connection in another part). Or, when you touch it/move it while running it can disconnect and cause a restart. Now, heat causes expansion, and I think that can cause a disconnect too. The connection to screen, and the drivebays (optical/floppy) should be looked at. (I'll spare you the LONG version of the Woodchipper's story, but Steve found a loose solderpoint where Floppy/CD hotswap tray had to connect, and that caused BSOD's by the dozen. A loose ribbon could do that too.) I trust you reseated the RAM? Or tested the RAM one by one? I seldom do Laptop repair, but Murf does that quite a lot. yes, extreme heat weakens bonding. A cooler pad for laptops could be useful. |

The latch seems to stay latched when I open the case and look at the CPU area it is only a little warm like lukewarm bath water or something.... If it is a loose solder connection that seems like it will be a pain to track down but I will inspect the board as well as I can. As far as touching or moving the laptop while its running all I do is type I have a USB mouse I use when I am at a table. The screen connection seems to be secure I haven't noticed anything flaky about that. Did I miss any of your suggestions? It's just a very odd problem the last mobo died could it have surged the CPU when it did? Could this be causing the problem? Sadly I can't figure out if it is something expanding and loosing a connection or something else somewhere else having trouble. Nearly every time I boot it up now it POSTs which seems to be odd to me I get the splash screen but cant access the BIOS or boot into windows it's frozen by that point but it does load the CMOS setting alright which means the problem is partially solved? WEll I am rambling so I'll cut myself off now.
Please note the guy that attempted to get into my admin account on the FTP server I have a tracert of your ip and a log of your activitys I assume it was just someone trying to be helpful at the moment. Please use Anonymous username to login thank you. Last edited by Dsopala; September 3rd, 2007 at 07:09 AM. |

hi
That solderpoint story was to illustrate that a ""shaky"" connection can cause BSOD. (the loose point was caused by slamming in the tray too hard.) Do you have any way to test the hard disk? The Last laptop I worked on would not POST, not even beep. The lady told me it had been beeping at her the last week or so, and windows would restart. (After several attempts to get it running, it died..). (She wanted her data, because warranty service desk said they did not do data recovery.) After I had looked at the hard disk in another machine (I used an IDE converter) I thought it had died, because it caused a hang during POST when I started, and later on I could not see partitions. But, after I put it back to the laptop and powered it up, it started. Some sessions of chkdsk were run, and data could be backed up. (Warranty service did diagnose that the drive was faulty, it got replaced, and it came back with a complete image of the old drive on the replacement.) I still recommend a memory test. as for hard drive connection, a drive health test. (WARNING, some diagnostic tools will wipe ALL DATA) Far as I know (some experience of long ago) a CPU malfunction while it is running causes a BSOD, and won't even attempt to restart the machine because the CPU is malfunctioning. Do you know what killed the original mobo? |

i have a simple feeling its a random damaged component inside the laptop due over-heating - although you cannot physically see it?
