Question about Panasonic CF18DJAMXKM Notebook

UPDATING PANASONIC CF29 BIOS ISSUE

While updating the bios from v16 to v17 the computer simply shut down. It had started uploading fine and got to roughly 7000 out of a 8000 hex numeral when it died. I think the floppy somehow got corrupted. We went through roughly 17 other machines before this one, with no problems. Now all that happens when power is applied and a boot is attempted, is the green battery (if installed) and computer power LED's on the right front light up. There is no hard drive activity, lcd activity, floppy drive activity etc. etc. We've already tried booting without several peripherals installed, keyboard, floppy drive, battery, and tried disconnecting the cmos battery for 24 hours, which measures 3.1 volts. I even tried booting with out the hard drive installed and didn't even get "No operating system found". Any help would be appreciated.

    FOR RTRAHAN: The two LED's on the front right hand corner light up. These are labeled "The battery pack status light" and "Power status light". That is the only noticable indications once the power switch is activated.





    FOR ASHISH13: Are you referring to the CMOS chip? Just wanted to verify



    Thanks to both for their help so far

    For rtrahan: I've tried changing/removing most of the peripherals and other boards while booting with no difference. I think it had to be the bios floppy that got corrupted because we unfortunately used the same floppy for two different machines before we knew we had a problem, with both machines having the same dead result. Both were updating the bios with the floppy and got to a count of roughly 7000 out of 8000 hexidecimally and then both just went dark, We had used this floppy on 15 other machines prior with no bad luck or issues.

    Seems like to much of a coincidence the motherboard would go out just when you were loading software..had to be something that was changed..perhaps the memory got corrupted, since you were loading at the time. Is there a way to swap out the RAM with RAM you know is working. Bad RAM would cause it not to boot past the POST and it sounds like it is not making past POST.

Seems the chip on motherboard is messed up. Please check the following link for your options if you can't manage to get to the BIOS. http://www.informit.com/articles/article.aspx?p=130913&seqNum=7

Buying a bios chip will be economical but will need extra precaution when installing also check this:

How to remove a bios password from hp 6720s


Why can't people put a problem in the right catagory?
Generally, you can remove the Bios backup battery or use the jumper on the motherboard to reset the bios completely.
Google "reset bios" to get an idea of how to do it, or do the same in Youtube for a video. Lots of them are out there.

How do I get the battery out of my acer laptop


Your Model of Aspire has a different battery release method, see attached pic on how to do it. This is a pic from your User Manual, you can download it from here Download Acer Aspire E1 572
Manual
. I suspect that the information you have been given regarding battery removal and passwords refers to removing the cmos battery as in a PC in the hope that it will clear Bios activated passwords.

Don't start up


check that all removable media is removed from computer, flash drives etc,if this message still appears the reinstall your os, there are several reasons for this error. You may have to replace your hard drive if that is the issue- you would know because after reinstall (if it makes it thru it) it will only crash again, this is much too big of a subject to sum it all up here and now, good luck... more questions just ask

How do i reset my computer to an earlier date?


Most computers have a RTC or "real time clock" in the BIOS. BIOS (or "Basic Input Output System") controls how data gets into and out from the processor (via keyboard, disk, etc.). Be careful making changes. The BIOS is normally only accessable when the computer is powered on or reset, and then only while performing the POST (or "Power On Self Test"). At this time your screen may display text describing memory, drives, controllers, etc. Some machine have a "silent boot" enabled which displays a manufacturer's graphic or logo instead of this data. It is during this time the the BIOS may be accessed. Depending on the manufacturer of your computer, a key (Delete, Escape, F1 or some other) or key combination (ALT + F1, ALT + S, or some other) will be needed. It is required to press the key or key combination prior to the Operating System loading message(s). This can be done be repeatedly pressing the key (or key combination) once every second (or two) during the POST. Holding the key(s) down the entire time - or pressing them too often will result in an error, and require starting over again.

Once the BIOS screen is presented, you will have to scroll the entire page(s) to find the clock. Most BIOS brands have more than just a single page of settings. Using the the up, down, left, right, PgUp, PgDn & Enter keys - navigate to the clock hours and minutes and adjust as needed. Make sure that you SAVE changes before exiting the BIOS screen. Upon exit, the computer will reboot with your settings.

Your Operating System may also provide a way for you to change the system time (and date) as well. Try clicking on the time / date to see if it will bring up a dialog box that allows you to make the change.

I hope this helps and good luck! If my answer was helpful, please rate it "4 thumbs up" Thanks!

If your mouse and keyboard work properly with another computer or laptop the problem could be :
A) if devices are USB :
- defective USB port : chose another USB port;
- USB port inactivated in BIOS : check and activate;
- motherboard defective : replace motherboard.
B) if devices are PS/2 :
- damaged PS/2 ports : buy a PS/2 to USB adapter for your mouse/keyboard or buy USB mouse and keyboard;
- motherboard defective : replace it.
