Have I protected my laptop enough in case of loss?

Question

Encryption

Good afternoon!
I usually work with a laptop at home, but sometimes I take it with me - on a business trip, on vacation. Accordingly, I am afraid of losing it, forgetting that it will be stolen, and so on. I store some especially important work data in encrypted form, I backup, but I worry about "everyday things". For example, the browser logs into a Google account and gives access to mail, and in the history you can find the Internet banking sites where I go. I don’t even want to think what some cheerful schoolboy / student can do, who will find my laptop and be able to boot. On the other hand, making the use of a laptop inconvenient - for example, entering a password every time you log into gmail - is not the best way out.
Now I have put a password on the screw itself through the BIOS, i.e. it must be entered each time you turn it on or reboot. When exiting sleep mode, there is a simple password for the Win7 account, judging by superficial Google, to bypass it, you still need to restart the laptop, which will lead to a password request for the screw.
Do you think this is enough to protect against the curious who found the laptop? What else can be done? I thought about encryption through TrueCrypt of the system partition, but 1) how much does it slow down the work? 2) couldn't find if it asks for a password when waking up from hibernation? 3) how much is it necessary compared to what has already been done?
Thanks for answers!
UPD: I'll clarify, the password is not on the BIOS, but on the screw itself. Those. remove the screw and plug it into another computer, it seems like it will not work.

Answer 1

The methods that you practice cannot fully protect you. In your case, you need to encrypt the entire drive. It's not as slow as they say, but much safer.

Answer 2

From dolboklyuev the password for the screw will save, I think.

Answer 3

Trucrypt is correct. Someone began to threaten the author, and therefore the original project is not developed, but there are forks.
1) does not slow down.
2) no, but the OS asks.
3) Necessary, because just reset the bios password, or pull out the disk.
