Question about IBM ThinkPad T42 Notebook
The AC power keeps on and off, however, it still charges the battery. The AC Power ICON on and off frequently, the screen keeps flashing.
This is not a good sign!
If all physical connection seems fine, it could mean something is wrong on the power modules of the motherboard! Please try another power adapter to see if it's the power adaptor's fault. If not, get it into lenovo service centre for check-up, as this could damage your laptop motherboard's power modules permanently!
This happened exactly what I had on my good old ASUS laptop, I ended up replace the motherboard. Pay little money to get it serviced before you have to replace the whole motherboard!
