Most laptops work perfectly fine with the battery removed and for those who cannot replacing it with a large capacitor is usually a solution.

Using a capacitor sounds interesting but also pretty tricky, have you done that yourself?

I didn't as I never had a laptop with this issue but I have seen it done on a smartphone.

I thought a lot of laptops don't work without the battery, especially the increasingly common unibody types.
