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:

My computer wont start on after bios update failure


And nothing will happen. Do not PERFORM BIOS UPDATE unless strictly necessary. Do not perform BIOS UPDATE without CHARGER plugged in and be sure you have enough power for 10 minutes. NOW... If you are lucky, in service they will be able to REWRITE your BIOS. Check HP website for service in your area. If not, your motherboard will have to be replaced. Good luck. Keep us informed of the results.

If computer SHUT DOWN while reading BIOS FILES you might have a little chance to repair it. Unplug battery. Charger must not be connected. Press POWER for 30-40 seconds. Plug back battery. Press power. And pray before this.
IF this will not repair it... the two options described before will...

Alright, so first of all bios always gives you a strong warning. Updating a bios can if gone wrong can always cause a lot of problems. Just follow the instructions and you will be fine. If you download the bios from the website you will see a Pflash.exe This should allow you to flash the bios from the Operating system. Be sure you do not have your pc unplugged during this or try to shut it down while it is updating. I am not sure if the new bios will add the option to boot to usb.

Getting a CMOS checksum bad error when starting my Acer M5640 Desktop with Windows 7 Thanks Daniel


Solutions to CMOS Checksum Bad Error

The CMOS Checksum Bad Error can be fixed easily by following the listed steps carefully.

CMOS Battery may not be functioning properly

If you suspect that your CMOS battery is not functioning properly, you can easily change it. Before changing your battery, reboot your computer to make sure that the error still exists. If it does, go into your CMOS and write down all of the settings. If all the settings are lost, you can usually retrieve them from your computer manufacturer. Now locate the battery and remove it, you might need to consult your computer's manual or technical support to remove your battery (the battery a flat, shiny silver colored and coin-shaped). Take down the CMOS battery's information such as volt, size, etc. Once you have your new battery, you can replace it and reenter your CMOS settings. If your battery was the cause of the CMOS Checksum Bad Error, you should have solved the problem.

Your BIOS may have been updated

If your BIOS have been updated recently, your CMOS settings may have reset. Make sure that the values entered in the BIOS are correct or simply reset them to the default settings. If you believe that a virus has updated your BIOS settings, run a virus scan and make sure that the BIOS settings are back to the default.

The Computer may not have been shut down properly

Sometimes when running MS Windows, if you shut down your computer without first properly shutting down your operating system, it will corrupt the CMOS settings causing the CMOS Checksum Bad Error. You can easily avoid this error by making sure that you completely shut down your computer properly before turning off the main power. Usually this entails going into the Start Menu, clicking on Turn Off Computer/ Shut Down. If improper shutdown was the cause of the error, you may have solved the issue.

If the BIOS update doesnot work it probably should be a hardware issue. Check with Compaq Tech support if your system is in warranty.

Hello,

Okay, have you tried updating your system, usually, when update is done, drivers are also updated.

You can try the system update first and see if that would make any difference.

Let me know what happens next after you have done the update.

Good luck.

Booting problem


There are usually three main reasons that a CMOS Checksum Bad Error has occurred. They include:
  • CMOS Battery may not be functioning properly. The battery life may have expired.
  • Your BIOS may have been updated (either by user or possibly a virus)
  • The computer may not have been shut down properly e.g. shutting off the computer's main power without first shutting down the computer (MS Windows requires you to shut down your computer before shutting off the power).

Our computer is telling us we need to update the BIOS computer shuts itself off


All BIOS components are serviceable via a firmware upgrade that is known as "flashing" this process is called "updating the BIOS". The process itself is fragile since any power fluctuation during a flash may irrevocably corrupt a BIOS' firmware. Great care will need to be taken in order to safely accomplish this.

This guide will help you flash your BIOS by taking precautions and walking you through each step. Not all computers will have the same BIOS manufacturer, let alone the same process, but many have similar steps and precautions.

Emachine T2385 Won't Boot in Normal Mode past Windows XP Screen


The first thing I would check is your video card (usually driver) problem. Start windows in safemode with networking. If this problem has occured after updating the video card driver you may try rolling back the driver to a previous version, otherwise try

Once windows starts you'll want to go to the start menu and find and click run. In the text box enter the command "devmgmt.msc" and hit enter and the device manager should appear. Look for display adapters and left click the + and you should see your video card. Right click the video card and select properties from the drop down menu. Select thr driver tab. Now if the problem had occured after updating the driver, choose rollback the driver from the menu. If not try selecting the update driver option. After updating/rolling back the driver you'll want to try restarting in normal mode.

If it still won't start in normal mode you can try troubleshooting the video card under the general tab in properties, though to be honest I've found this rarely usefull but it might help you. Otherwise you'll want to make sure that your videocard is enabled in BIOS. A quick totorial of BIOS if needed http://www.tomshardware.com/reviews/bios-beginners,1126.html.

Otherwise it's likely a physical issue with the graphics card. Since you've tried reseating the card already it may be that the card is damaged and will need to be replaced.

My Acer Aspire 4315 Can't Shut Down Normally


That usually means a Windows problem (not hardware).

The best way to identify the issue is installing a fresh copy of Windows and all of the updates (I know is a lot of work) and see if still happening (i bet it won't)

Good luck!
