Given that decades ago, the Russians embedded completely passive microphones inside paintings and have them as gifts, undetectable to most equipment…yeah a full blown laptop should almost be an admission that “hey we’re trying to bug you”.
Nah, then they will try to get the information over other channels. Take the laptop and gift it to someone over craigslist or a similar site. It will take them some time to realize they are not monitoring you, using a persona, but a soccer mom from the suburbs who is really into social media and cooking.
It won't make anything more secure, but it can buy you some time and waste the attackers resources.
Now I'm picturing a series where actually it turns out that the person you sold it to is a major drug dealer or something and it plunges them into a web of international intrigue when the foreign government tries to blackmail them and then they come after you as revenge.
