Instead of just saying help, it would be helpful if you could provide more details. Do you have a model number for the laptop as I can find nothing about a laptop called an IPC Widebook.
I am assuming you wish to get into the BIOS for some reason which is where you will find the boot menu.
Have you tried tapping the delete key after pressing the power on button?
You could also try F2 or F Or F!2. But your laptop Will tell you what key to press. After you press the power on button a lot of text quickly scrolls down the screen, its on there towards the bottom, but you can also press the pause key which will give you time to read which key it is to enter the BIOS.
