Hi SarikaSingh,
Thank you for reaching Microsoft Community. I'm sorry to hear about what happened to your Surface Laptop 2 and I understand that there important data on the device also. Have you tried connecting the device to an external monitor? If not yet and possible, kindly try to do so and see if it would display on the external monitor. This seems to be a hardware issue already on either the device screen or the drive not booting up. I suggest contacting our live support for further assistance on this and also to check for other options available. You may contact them through the numbers listed in Global Customer Service phone numbers (microsoft.com) under For Business users. This works with Home users also, just select Surface then Home as a type of user in the IVR prompt. You may also reach them through this page: Contact Us - Microsoft Support following the steps below:
1: Go to Contact Us - Microsoft Support and sign-in your personal Microsoft Account
2: To make sure you are using the correct locale of the page, click the Globe icon on the lower-left corner of the page then select the country you are in.

4: On the next page, select Surface then Technical support then choose your Surface model and click on Confirm
5: These options should appear depending on which is available on you country. It would also show the available time of support if in case you accessed the page out of the time of operations.
You may select **Provide your phone number and a support agent will call you** option and you will be ask to select and confirm your phone number then click **Confirm**. You will then receive a phone call from support in a while.
