Is it possible to make an older IBM ThinkPad T41p laptop a little bit faster? Yes, it is if you upgrade the CPU as it explained in this tutorial.
I learned that with a simple BIOS flash, the original 1.7 ghz pentium M “Banias” CPU (130nm process, 1mb L2 cache) that came standard with the T41p can be upgraded to a 2.0 GHz Pentium M 755 “Dothan” CPU (90nm process, 2mb L2 cache) which was available in the later T42 models.
Do you have an older IBM ThinkPad laptop that came without internal wireless card and wireless antennas but has a slot for the wireless card on the bottom? Now you can upgrade your laptop by installing internal wireless card and antennas yourself using these instructions.
In this project we added an internal wireless adapter to a Thinkpad a31. This is possible since it shares the chassis of the Thinkpad A31p which included internal wireless and bluetooth, at the time, cost about $1000 more.
This guide was made for an IBM ThinkPad A31 laptop but should work for some other ThinkPads too.
First of all make sure your laptop has a slot for the wireless card, otherwise installing antennas is absolutely pointless. Usually you can access this slot from the bottom of the laptop. The wireless card slot looks similar to a memory slot.
this projects uses one:
- Dell Truemobile miniPCI 1400
- IBM replacement a31 antenna system
Your IBM ThinkPad laptop screen (or any other laptop) went blank? Check out this article.
I could get the screen to come back on momentarily by toggling Fn-F7 a few times, but after about 10 seconds it went blank again. After rebooting, same thing — 10 seconds and blank.
Upon closer inspection, I noticed that I could actually see the windows very, very dimly on the screen. However, it was so faint I couldn’t see a cursor or read any text but the screen was definitely trying to project the image. So I hooked up an external monitor and the image displayed just fine.
The author of the above mentioned article article tried replacing the screen inverter board first but it didn’t help. After that he replaced the LCD screen and this resolved the problem.
From myself I would like to add a few more tips for troubleshooing and resolving laptop backlight problems.

This guide will show how to open up the LCD screen on an IBM laptop and replace the failed backlight lamp (CCFL).
LCD panels become useless when their backlight lamps fail. It can fail as early as one year after production, but most units fail after three or four years of use. My ThinkPad T23 is a little more than three years old and its backlight started to show pinkish tone. Moreover it was flickering when first turned on. The symptoms usually disappeared after several minutes, but it became really annoying. So I decided that it is time to replace the backlight.
I have an IBM T30 that has a video problem: vertical lines appear and no video…but works perfect on external monitor.. Changed cable and ensured proper seating of the connectors. Vertical lines different thickness with new cable but still the same problem.
Could it be a dead LCD display?
I hope it’s not the mother board!!
