    Hi, I have the same issue, and th ac adaptor is working fine. When I run the IBM check on the battry, it says it is good and fully charged. If I remove the battery and run t same test, it says bo battery intalled. I guess this means thbattery is working, the ac adaptor is working etc.. Just won't run from the battery. Anyone have any further ideas? Thanks.

Check the ac adapter. It seems your adapter is not charging it. Either the ac adapter or your dc port may be the problem. Is this the correct adapter, is it giving the correct voltage. These should be considered also.

 

Hope this helps you

IBM thinkpad T30.The power button turned on then nothing boot up power LED light is on.Some time it boot up and run but then it won't do it nextime after it been power off. Battery for BIOS is good, Main...


There could e a problem with the battery. A fast check to determine whether you have a problem with the power adapter, power cord or the laptop's battery is to turn off the laptop, remove the battery, connect the power adapter, turn on the laptop & see if it works.
If the laptop works directly from the power adapter with the battery removed, then the power adapter is good. In this case we can suspect that the battery is defective & needs to be replaced.

Try also to reseat the main components of the notebook: the battery, the AC adapter, the memory modules, & the hard drive.
After that try switching it on & see if the problem was fixed.

My ibm laptop contionusly beeps and says power scource is battery,when i press esc, it boots normally and shuts down in about 15 mins to half an hour


Either:
A. Bad battery
Or
B Bad power supply.

Sounds like the battery isnt charging correctly , the beeping is warning you it is running out of power.

Take the battery out , and boot normally with the ac adapter.

Does it work?

If yes, Get new battery. about 70-90 dollars.

If no. Get new ac adapter. 20-40 dollars.

X41 Tablet PC the battery shows good but computer will not work


Some times a battery can pickup a dead short, and even though it shows a charge it will not work. The other possibilty is the power management chip on the mother board. This chip allows the computer to charge the battery and switch from battery to AC. (Right now I have a Thinkpad that will only run on battery, bad PM chip) Try replacing the battery first, if that doesn't work, then unfortunately the motherboard will have to be replaced.

Usually, hitting the 'F7" button while holding down the 'Fn' button (function button) will brighten your screen.

Also, if you're running on battery, to conserve battery power, most notebooks will dim the screen... you can override those settings by going into the control panel and into the power settings (easiest found on the old 'classic view').

If none of that works, your video display could be starting to go bad. Let us know how you fare and we'll go from there!

Good Luck!

Remove the battery. Check for voltage at the connector of the AC adapter. Plug adapter into the lap top and turn on. If it runs, yes, a new battery is needed.

When power up is attempted, does it make any sounds, can you hear the fan running or do any of the indicators light up? If so, you are getting power to the laptop. If not, you probably have an internal power supply problem.

T23 Thinkpad could not power up


Your machine should run without the battery, just plug it into the power supply. You may check the powersupply itself. Maybe the power supply was bad and not the original battery. You can pickup one at a computer store. A universal costs around $100.00 to $120.00. The power supply is the (usually) the rectangle box that is part of the power cord. Let me know if that was it. Good Luck. Tim
