When rebooting I received the blue screen along with this message:
receive following error Stop: 0x000000ED (0x81B899A0, 0xc0000006, 0x00000000, …)
When I attempted to reboot it hung up while trying to execute agp44a.sysI have the same issue with a THINKPAD. Just keeps booting up. goes to screen asking if we want to start in Safe mode or normal...No matter which option is selected the windows fails to load and is redirected to the blue screen STOP-- Unmountable something or another. Error 0x000000ed. Then it automatically cuts out of that screen back to booting up again. I believe this is the error. Everytime it reboots I only get a flassh of the blue error screen so this is as close as i have gotten to the correct error code. Is this toast? Can this be salvaged? It was working fine then it stared to lag a bit a day or two ago. Then yesterday--It just went to crud....so frustrating because of course I did not run an external back up on the drives.
please try to turn off your computer and take off the battery and again put it back and try to turn the switch on.
But if it is still have the problem and no changes at all.
The problem is in your VGA driver.
follow this instruction.
1. Re Start the computer
2. Press F8
3. Start it with safemode
4. Re-moved VGA driver and Re-Start.
I strongly advice that you should go to a technician specialist and ask to change a compatible Driver to your unit.
Hopefully i gave you a better idea to fix your problem.

Re: Cannot reboot IBM thinkpad t-21
Hi and welcome to FixYa,
Offhand and based on the description, it would appear that the hard drive of the computer is either faulty or the programs stored inside are corrupted. Corrective actions could be any of the following:
removal of the hard drive and connecting it to a SATA/IDE to USB adapter. Thereafter connect said HD to the USB port of a 2nd PC and perform disk maintenance. This would probably be the best option since if it still can be recognized and accessed, this procedure would allow you to back-up/copy your important files;
re-partition, re-format and re-installation of your Operating System. But then of course this would mean that your files would be deleted;
do a repair using the installer CD;
worst case scenario is a hardware problem with the HD which of course calls for a replacement.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

some machines. This takes you into BIOS, change your primary boot device to

for files to be installed. Select the part of the hard drive you wish to use
for your operating system (usually the largest) and select partition this
drive. Delete any previous os, and reformat hard drive. (Be aware this removes
everything saved on your hard drive, so always back up first) Re boot
afterwards and reinstall operating system.

If the administrator password is blank, just press ENTER. 5.At the command prompt, type chkdsk /r , and then press ENTER. 6.At the command prompt, type exit , and then press ENTER to restart your computer. This takes a bit longer, but the system should boot back into Windows.
During the boot at the THINKPAD SCREEN press the Thinkvantage key ( Blue button ) it will launch rescue and recovery and allow you to reboot factory.
This only works if you did not corrupted/deleted the rescue and recovery hidden partition on the HDD.
Otherwise you will need the rescue and recovery CD to proceed. IBM/Lenovo support should be able to provide you the CD.
