I have an IBM ThinkPad T22 It is about 2 - 3 years old I am not totaly sure because I received it as an x-mas present this year. Every time or just about every time I shut it off or put it into sleep mode or close the screen it locks up forcing me to take the battery out to shut it off because alt+ctl+del. does not work when its frozen nor does the power button. It is becoming a presistant problem. It will come up saying "hard-drive not found please re-install hard-drive" or operating system not found. I believe it is the cmos battery. I re-set the time and sometimes it works other times it doesn't sometimes I have to plug it in for a few minutes then it boots up into windows just like I pulled it out of the box. It is still under warrenty untill september of '04. My dad had to re-install IE6 because it got messed up when it forgot the hard drive. can someone help me? This laptop was really expensive and I appreciate any and all help thanks.
