A letter of volatility is issued by the manufacturer of electronic devices and computer equipment, citing some of the technical specifications of the onboard memory. This can be used by customers to comply with security requirements and to guide them in handling the devices. The customer will usually be another manufacturer, repairer or company using lots of technical machinery and computers, though an individual may also request a letter for their own purposes.
The main function of the letter of volatility is to outline the volatile and non-volatile nature of the memory on the device. In other words, whether memory can store data when the device is powered off (non-volatile) or not (volatile). Somebody may wish to know this for data security, especially if the data is highly sensitive, such as that on Government computer networks.
Some companies like Cisco refuse to issue letters of volatility so they cannot be held liable for data losses or privacy breaches.
List all the hardware in a table, or in such a way that it is easy to read.
Next to each piece of hardware note whether the memory is volatile or non-volatile.
Confirm what this means to reassure the recipient.
If the letter was specifically requested, thank the recipient for their custom.

Dear Mr. Walker,
I can confirm that the memory on the series of HP Deskpro laptops you enquired about are volatile, meaning power has to be maintained for any data to be stored. Within seconds of powering down these systems, all data within the memory will cease and there is no way of recovering it.
HP-Compaq Deskpro EN 6600
I therefore advise that removing the memory and carefully disposing of it, cannot result in any data breach concerns.
We thank you for your interest in HP products,
