| | Installing this wireless adapter couldn't have fried the motherboard, right? ||I would not have thought so .. the software may have caused an issue --- as the PC boots tap F8 you should get a menu - choose "last known good configuration" ---- if that does not work, reboot and again tap F8 as it boots and this time choose safemode - then see if you can restore start>programs>accessories>system tools>system restore> choose a date to before the data you installed the wireless adapter software
Remove the battery and power cord. Hold the power button in while connecting the power cord hen the battery. This will reset the power distribution settings. If this does nor resolve the issue then you need a new power supply. With this machine a new computer would be less expensive.
The laptop screen is secured to the laptop with screws at the hinges. There are usually two screws per hinge. The LCD screen has one ribbon cable and possibly a power connector for the back lighting attached to the motherboard near the hinges. Disconnect these before you lift the LCD off the base, they are under the plastic panel above the function keys next to the hinges.
i have the same problem. actually its a common problem for many T21 and other old IBM laptops.
i searched that you have to take all power (batery, adaptor)
press the power 10 times and press it for 30 secs then reinsert the battery or adaptor and try to power it on.
they say its done to discharge a certain capacitor that got overcharged after overcharging the battery.
that worked for me before but now my T21 wont start any more with this process.
