I recently bought a used Thinkpad 770 and I cannot get it to start up. I get the Thinkpad screen which goes into an error box asking me to change the date and time. If I do not the error screen stays on with a couple of long numbers. If I do change the date and time I get something that looks like this: o off > on l. I know this sounds crazy but all I can do is turn it off. Nothing seems to clear the screen. Am I just totally new at using one of these or is this something others have seen? What can I do to fix it? Is this telling me the battery is dead?
I have the same computer and I know exactly what you talikng about, the Off>On screen you get, the computer wants you to turn it off and then back on again, Just push the button to turn it off and then hit the button to turn it on, don't wait to long between turning it off and on again. it should just be a quick off and quick on.

Take the battery out and see if the system works on AC only. Sounds like you need to reinstall the OS and you may have an issue with the thinkpad not keeping the time and date. This is related to the other battery called the CMOS battery. This keeps your date and time accurate when the system is turn off.
Shure 'nuff. Sounds like either the inverter or backlight. I would go for the inverter as that seems to be the more common item to fail, it usually is cheaper than the backlight, and easier to replace. If you need to directed to an online maint manual, let me know. Ron
Error 19990301 on a Thinkpad 600 usually indicates that the hard drive is not properly connected, and error code 19990305 signifies "no bootable device". So, it's the hard drive.
First of all, I would try removing and replacing the drive to see if that cures it. You can get the service manual from Lenovo at http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=LWIK-3SYPX2
If this doesn't fix it, the hard drive is faulty. However, small size hard drives (10 or 20Gb) which suit these older machines are very cheap on eBay.
There is either a problem with the graphics driver not starting properly or the boot.ini file of the operating system is corrupt.
First thing to try is press F8 on boot up and this will take you into safe mode, if prompted for a password just press 'enter'
When in safe mode highlight the line 'Last known good configuration' and press enter for a reboot, if all boots ok then it should be right.
If still no screen, press F8 again on next boot up and this time select boot windows in safe mode and if it boots ok, there maybe a graphics fault or a driver error for something that starts on boot up, as in safe mode only the minimal drivers start (hence safe mode).
If you get into safe mode first, right click my computer>properties>hardware tab>device manager, then go down the hardware list to graphics adapter,and click on '+' sign to your adapter, right click on line and select uninstall.
Restart the pc then it will be automatically installed again and the drivers loaded.
If you are still unable to boot then it is a process of ilimination to find what is causing the problem, but it will more than likely after trying the above be a windows system file error and require you to use your XP disc for a system repair.
