Lenovo ThinkPad T43 Notebook PC - Answered Questions & Fixed issues

Traditionally with ThinkPads:

1. The BIOS password can be reset with the CMOS.
2. The Supervisor password cannot.
3. The HD password cannot.

If it's the harddrive that's locked you will have to replace that. If it's the Supervisor password you need to replace the system board which kind of defeats your purpose.

Click Here to get the proper driver without a cd, you must know your operating system when going here in order to get the proper driver selection. I do although recommend the pcl 5 over the pcl6 as it has way less bugs... Hope this helps and if so please mark as FixYa!!

There is no *LEGAL* way to remove that software.

You clicked "I agree" to allow that software to be installed.

If you have a "bootleg" version of Microsoft Windows, follow the hyperlinks offered by WGA to "get genuine Windows", i.e., pay some money to get a valid product-key for Windows.

Or, telephone Lenovo, and order a set of "System Recovery" CD disks. If your computer was originally shipped with Windows XP installed, those disks will re-install a *VALID* copy of Windows XP.

Depends on the computer you are using.

If the computer you are using is low on resources, as the Pentium M in title, then one of the 'fastest' ptp fileshare software is Utorrent, as it needs little RAM and also does not need a big CPU.

If instead you have a powerful computer with 2GB RAM and pentium duo, or more, then I recommend Azureus-Vuze, that is one of the most complete torrent software.


Download - µTorrent

Azureus, now called Vuze : Bittorrent Client

Right click on "my Computer" choose properties, then choose hardware, then click on the device manager tab. Scroll down until you see sound devices. Right click on your sound device (sound card) and choose uninstal. After the device uninstals, look at the top tab that says actions..Then choose "scan for hardware changes" This will reinstall the sound card and should fix the problem.

The drivers for IBM and Lenovo laptops are available at the Lenovo support website.

Lenovo ThinkPad... | Answered on Mar 19, 2009 | 375 views

First thing is to check if the wireless device is working. Go to Control Panel - System - Hardware - Device Manager. Click on Network Adapters. Do you see the the Wireless card?
If not in Control Panel click on Network Connections, do you see a Wireless Connection? If not you need to install the correct wireless network driver, Check the IBM site again, there should be another wireless driver (there are a couple of different wireless card installed on T40 series ThinkPads).
If you succeed in installing the wireless driver and it is enabled.
Then click Control Panel - click on Network Connections - right click on the Wireless Networl Connection - Click on Properties and check if TCP/IP has been installed, if not install it. Check TCP/IP properties - make sure it is set to Obtain an address automatically and Obtain DNS Server address automatically.

Check the wireless settings on your other laptops, use this information to configure the wireless on the T43, ie the SSID, WEP or WAP settings

You should be able to connect to your wireless router and Internet now - let me know how it goes,

remove the battery large.
then run on AC pack only
#1 top failure of all mobile PC is that battery, so unplug it
then test with AC pack only.
work now.? and all vents must be clean, end to end. not just fan.
there i no fuse it uses current regulator, imagine genius magic electronics fuses that never blow out, and bingo.

OK big battery out, an RTC coin cell fresh.
then fan blows.
next is BIOS, do the BIOS screens work if not the mobo is dead.
have 2 RAM stick on the 2 slots>? try one at a time
run the PC with all modules removed, (options)
remove hdd?
remove, dvd drive.
think like this. Get bios working first
learn that modules can short, and when they do the power regs shut down.
so we unplug all things to the mob,
until only 1 ram and cpu remains.
see? (this is called power overload fault isolation tactics)
even the screen only can be dead, you never mention text showing
you can test the mobo with external screen via that rear (?)_ VGA jack what if that worked, did you learn something here, sure.
this pc has tons of modules to pull, even bluetooth. wifi, sound and more. if you look at all parts inside or sold by ebay, bingo. lots
