Panasonic CF-18 Memory Issue

Hello,

First post hopefully someone can help me out.

I have Panasonic CF18 which started blue screening and then immediately rebooting. When i got a dump of the errors it pointed to memory issues. I replaced the onboard memory with a 1Gb Dimm but the same errors kept continuing. It is basically unusable as of the moment. The system states the memory is 1.25Gb, is there a 256 dimm on the motherboard? i cannot find any other potential slot. I am thinking the onboard memory might be the issue. Has anyone seen similiar. I was going to reinstall XP but i dont want to go through all that if its a memory issue. Anyone have any ideas?

Much appreciated
Stu

 

Stu,
Have you tried it with the memory stick out? That will answer the first question. It does have on board memory.

Yes i did and it blue screened. Just wondering if its worth reinstalling it from scratch, its been in use for a good few years now

 

so i tried various things and the laptop kept freezing and or crashing out. so i decided on a reinstall. eventually got a cd usb that the system seemed to like started the reinstall and get an error #1802. Restarted and tried a repair again got the error #1802. Decided to take the CF-18 Series Product Recovery CD Rom 1 which had been sealed and copy this to new cd to see if there was a corruption on the disc, it copied fine no errors. Now when i power on i get Invalid Partition Table... and i can go no further. Cant seem to get it to boot off the cd. Ordered replacement set of discs off ebay. Fingers crossed but i think it may well be gubbed. Any opinions on fdisking the whole hard drive and seeing if that allows me to start the reinstall? The second attempt failed at about 3% complete. Suddenly no onboard cd or floppy is a serious pain!

 

did u checked ur harddisk?

 

what do you mean? sorry did you mean did i check disk etc then yes i tried that a while ago

 

Sometimes the reinstall favours only 1 of the 2 usb ports
Try booting with the cd in the other usb port

just tried that - no joy. i think i am going to have to remove the hard drive, attached it to another pc, fdisk format it and see if the system will then see. i think the failed reinstall has corrupted it... braw!

 

If you are right about the onboard memory, then that would cause failure on installations. Is there a way to verify the onboard ram is good or not?

 

I am trying to find a way - memory checks like those on the ultimate boot cd seem to say all is well... though some are still running

 

Are you having this problem after a fresh OS load or Recovery? Add any software recently? I had a compatibility issue with my Firewall Software and Antivirus that would cause a Blue Screen Stop error 8E and reboots. Using Recovery Pro 6 cause reboots as well. Everything is fine now just remember to disable antivirus when doing Windows Updates, Firewall install updates or any program that is going to hook into the Kernel. I'm not using Recovery Pro 6 either. We need a few more details about how you got to your problem. UBCD is a good tool but if memtest passes then you could be looking at software issues.

Good Luck and post some more details when you have a chance.

You can try Ctrl-F7 at the Panasonic screen (Boot up) to get to the embedded Diags and see how the whole system pans out.

well i am typing this on the CF-18 so thats a result what a relief... took some time. strange issues getting xp installed had to use an old version i had on cd eventually got that running now just getting drivers installed and it all patched. annoying the reinstall cds i got with the panasonic (bought from new) didnt work, ah well got a drivers cd off ebay which has worked for most.
i now have two unknown devices - one is the touchscreen as it iant working - i have dloaded the mouse driver for ? also what could the second unknown device be?

i did find this link which seems pretty helpful https://eww.pavc.panasonic.co.jp/pc/itn/drivers/d_menu_en.html#CF-18

thanks for all the help, nice to know theres advice out there!

 

stuarab,
Have you read this thread. Read through it if you have not already. Your unknown device is probably a hotkey driver, but you should have started with 2 unknown hotkey devices.

This is the state of the art so far, but we are still working on it.

I have seen issues on cf-18 only after upgrading the system to win XP Sp3. Its gives you BSOD. The main reason, I don't know yet. But here is my odservation. The intelproset is the first culprit, second anti-virus. Before you upgrade the system you uninstall the antivirus program and as much as posible upgrade the intelproset(intel web site) or just install the driver and let windows control the wireless system.

I’m curious what’s your full model number for your cf-18?
