I did check it, the thing does supply DC so it's probably the sensing/configuration resistor.

Did you measure the resistance from the sense pin to ground? I don't have a 135W power supply but my 170W supply measures 1900 Ohms from the sense pin to ground.

There have been several threads about this on the forum over the years. This one is quite good: viewtopic.php?p=218045#p218045

Without the hassle of trying to rewrite the EEPROM, replacing the system board is the only option.

Many many versions of Power Manager have been released over the years. Some releases fail to install or fail to function on some Thinkpads. The older the Thinkpad, the more likely there will be issues. For the T43, it is so old that the docs are not maintained or checked for accuracy. Finally Lenovo...

I installed XP on my T43 this past summer. This was from recovery disks, not a retail or oem XP disk. There are no unknown devices in device manager but I did do some manual driver updates. Lenovo's advice on their power manager driver version is not helpful for the T43. The latest XP power manager ...

Problem is the original batteries are OLD. Lithium batteries age, even if you don't use them. I simply ordered a new one off eBay, and that has been running fine. Generalizations like this are sometimes wrong. I have a Panasonic battery for my T23 that is close to original capacity after more than ...

Out of curiosity I nuked Windows 7 on my T43 (1872-4AU) and installed XP SP2 from recovery discs. Wireless WPA2 security is not supported in SP2 but is in SP3.

The WSUS history file says:
Version 9.2.1 -- 05.05.14
- NOTE: This version will be the very very last one supporting Windows XP and Office 2003

Have you used a WSUS version newer than 9.2.1 to update Windows XP? Does version 9.2.1 work to update XP now, more than 5 years after its release?

Here is the list of recent Power Manager releases. As you can see there is a revision number in addition to the Build ID.

I've read that the ADP3421 current sense circuitry drifts and ultimately prevents the computer from powering up. When you are at the end of the road and nothing has revived the computer, try shorting pin 27 to pin 28 of the ADP3421. That should disable the current sense circuitry in the chip. The da...

I have physically disconnected the microphones in all of my Thinkpads and un-installed the software. The cell phones are kept in another room from where I normally spend time.

All conversations in my house are conducted in the Cone of Silence as seen on the American television show "Get Smart".

Thanks!

Both *MAY* work if you use a different Bluetooth stack for each card.

As for upgrading your Bluetooth daughter card, yes. I currently have a Bluetooth 4.0 daughter card in my T60, it should definitely work in the T500.

What's the part number of the Bluetooth 4.0 card in your T60?

My network is rated for 60Mb/s download. Using a T23 with P III 1.2GHz, 1GB RAM, Atheros wireless N (42T0825), Firefox 48.0.2, and Windows XP SP3 I recorded a best download rate of 64Mb/s. The speed varied depending on which server I accessed for the test. I don't have a wireless USB dongle to compa...

Thanks much -

To replace thermal paste you need to remove the fan assembly. The hardware maintenance manual available at https://thinkpads.com/support/hmm/thinkpad-hmm.html tells how.
