Blues, The first thing I would try is to remove and reseat the hard drive. With the laptop oriented with the cover latch towards you the hard drive is on the left of the laptop towards the front end. -Flip the laptop over and locate the hard drive carrier door. -There is one screw holding the drive in place, remove it. - Lift the hard drive door up until you hear a click. -Slide the hard drive out of the computer. -Reinsert the drive and push the hard drive until it is fully seated in the hard drive bay. -Reinstall the retention screw. If that doesn?t work then you either have software corruption problems or hardware failure or both. Let us know if you have any other questions and please don?t forget to rate this post.

    If I understand you correctly you?ve installed another used hard drive and you received an error saying no hard drive found. Are you getting this error while going through the Windows install routine using an install CD?

  • tomj23 Feb 28, 2007

    From what you?ve told me I?m not sure yet. Assuming the 2nd hard drive is blank or can be reformatted (and is still in the laptop) try this and we should be able to start heading in the right direction:
    -Place your Windows installation CD in your CD drive.
    -Boot to the CD drive and go through the installation process.
    -At some point early in the installation process the program will inspect your computer for a functional hard drive to install Windows. If it doesn?t find one it will tell you in no uncertain terms. That will point us in the direction of an incorrectly configured BIOS or perhaps some malfunctioning electronics. Let me know what you find out and we'll pickup from there.

What does the error message - 49.4C02 - mean?

49 errors are often caused by the printer receiving commands it does not understand. Sometimes hardware failures but not often. To determine hardware or software, turn the printer off. Unplug any network or USB cables attached and turn printer on. If it will come to ready with no cables attached, then likely you have a print job that is causing problems. This can be fixed by installing the latest firmware from Download the Easy Firmware Update Utility version. To install this update you need to have the printer connected to the computer, so check the print queues to make sure that there are no print jobs pending, delete them if there are. Plug the network or USB cable back in. Wait a couple of minutes to make sure that the 49 error does not come back. If printer stays on ready, run the upgrade utility and your problems should be gone. If it is a hardware issue then a different set of trouble shooting steps applies. Post back if this does not fix your problem.

Hello there, At first, go to start menu, all programs, accessories, system tools, open System Restore. Restore your system to restore point created before installing The Print Shop.

Please run setup invalid configuration information

If this error message comes up when you boot up the computer, it means the BIOS requires configuration, usually the Time and Date is wrong.
If this occurs every time you boot up your computer and have changed the Date and Time then this could be caused by a flat BIOS battery.
If so, replace the BIOS battery and then configure the Date and Time and you won't get this error again.

Well I would remove all software to that hardware being the TV card. Reboot the pc see if the error regenerates. If not then I would reload the newest version off the manufactures site. As well I would go into the msconfig and tell it not to run on bootup.

Click on startup tab
At the bottom click disable all>>Close>>It will ask for restart
Restart the computer

You have used the system configuration utility
Check the box at the bottom Do not Show this Message Again and click ok

Click start>>All Programmes>>and clik the application you need to open.
