Re: My Ibm t49 the display shuts off as soon i as i boot...

There are several possibilities within two categories:

SOFTWARE (you are using MS, so this is more likely)
HARDWARE these symptoms can be caused by bad battery and/or bad PSU (AC Power Supply Unit)

Software: You may have a virus, or may have damaged the NT kernel, or some critical software components by installing cheap games or bad SW. Read the recovery instructions on your XP CD to boot and run recovery and/or utilities that might repair the laptop OS. If you have no CD, try booting and hitting F6 key after BIOS screen... then explore the options there. Next, try booting and hitting F8 key after BIOS screen... then explore the options there.

If there are no problems repaired or evident in software, you should remove the battery, plug in the PSU and try booting. If all goes well, your battery is probably bad. If NOTHING happens, then your PSU is definitely bad (or the PSU cable/jack/connection to your computer is bad)

Conversely, remove the PSU and boot only with the battery. If it boots up (or goes farther than it did before) then the battery may be low/damaged BECAUSE the PSU is bad. If your laptop does not even open/get at least to BIOS screen, then the battery is dead. Try recharging overnight with laptop off but plugged into AC. If it is the same in the morning, replace the battery.

Both the battery and PSU can be checked with a VTVM, to compare voltage/output levels, with the ratings on the labels

I got IBM think pad T49 but it is very slow now. Experts said that i need to reboot this computer to get back normal speed but i lost my reboot CD. could u help me to reboot my thinkpad please

Your only option if you don't have the reboot cd's would be to find a windows xp, vista or windows 7 cd. Install windows and then go to this page to download and install the hardware drivers for your laptop. They have drivers for all the operating systems.
At this point install any software you want to use on your laptop. Be sure to go into your BIOS and set the 1st boot device to the cd drive so that way it boots up automatically from the windows cd.

Hello, I have an IBM ThinkPad t40 and my battery will not charge. It runs on AC power but shuts off as soon as AC is removed.

You should replace the battery. I wish I had a better answer, but that's pretty straight forward.

T40 Monitor Display

I assume you are running window XP or vista?
Go to
Start>Control Panel and look for Power Saver, or Screensaver options. There will be settings there for determining how long, if at all, your display will take to turn off.

Shutting off

sounds like you may have the numeric overlay turned on. To turn it off hold down the FN key and press F11.
