According to the Passware Kit Forensic company, any computer that has hibernated even once with a mounted TrueCrypt or BitLocker hard drive is vulnerable, as their product can “instantly decrypt the hard disk even if the computer is no longer running”.
ZoneAlarm DataLock (discontinued 2012), a third-party whole-disk encryption product, during the initial encryption stage disables hibernation. Afterward it interacts with the hibernation feature so that the encryption password is required on waking from hibernation.
If you do use BitLocker or TrueCrypt, you need to configure the encrypted system so it doesn’t accidentally go into sleep mode. Using the Power Options applet in control panel, set “Put the computer to sleep” to “Never”. If the computer has a sleep button, set “When I press the sleep button” to “Do nothing”. And be very sure you never choose “Sleep” from the options menu for the shutdown button.

Windows 7 Bitlocker requires TPM
TPM stands for “Trusted Platform Module”. It’s a chip on your computer’s motherboard that helps enable tamper-resistant full-disk encryption without requiring extremely long passphrases.
What is a TPM, and Why Does Windows Need One For Disk Encryption?
How to Check If Your Computer Has a Trusted Platform Module (TPM) Chip
Windows 10 Bitlocker TPM is not required
You can use BitLocker without a TPM chip by using software-based encryption, but it requires some extra steps for additional authentication. How to use BitLocker Drive Encryption on Windows 10
