Laptop white screen

[jar17]

Hi

I wanted to check if my laptop can be upgraded but after opening it , it won't post anymore but show a white screen. Does anyone have ideas why is that and what to try? I have checked the screen cable and it should be good, I get black screen if it's not plugged

The laptop is: HP Pavilion Notebook - 17-f100no

thx

@jar17 Here's what you need to do, to identify the issue and resolve it accordingly:

• If not done already, check if it works fine on the BIOS screen to identify if it's either a hardware or a software issue:
  • If it works fine on the BIOS (Accessed while tapping F10 during a restart) it's a software issue & I suggest attaching an alternate monitor to your device and creating a new user account to check if that works better, for starters)
  • However, if it doesn't work within the BIOS either, I'm afraid it's a hardware malfunction.

While you respond to that, I have a few more steps that should help: 

Perform a power reset (no data loss) using these steps: Click here, proceed to next step if this works

Attempt to run a test from the HP hardware diagnostic tool, using this link: Click here for details.

If the issue appears on the diagnostics, it could again, determine a hardware failure,

If they don't appear on bios & the hardware tests passed: please update the BIOS & Chip-set drivers from the HP website using this link: Click here

if the issue persists, reinstall windows using the recovery partition or the recovery media to fix the issue,
use this link for details on performing the recovery: Click here

thx for your reply! I think I was not clear enough - all I get is white screen, no BIOS no OS, nothing, just white.  I tried power reset but that did not help.

Thank you for posting back. 

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

• Did this happen after a recent window or software update?
• Have you made any hardware/software changes?
• Did you make any changes on the settings of your PC prior to the issue?
• When was the last time it worked fine?

While you respond to that, let's try these steps: 

Hard Reset: Follow steps from the link: https://hp.care/2GnkMa8. (do not skip any troubleshooting steps even if you feel steps are repeating)

BIOS default:

1. Turn off the computer and wait five seconds.
2. Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
3. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
4. Press F10 to Save and Exit.
5. Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
6. Follow the prompts to restart your computer. 

Hope this helps! Keep me posted for further assistance.

The laptop stopped working (white screen) after I had opened the case (removed screws) and unplugged some cables. I have tried putting everything back except CD drive but now it doesn't work. When trying to fix the problem I have only the necessary hardware plugged such as keyboard. Because it's really hard to try and work with all the cables attached,

When I try to enter BIOS the laptop just bleeps when I press F10 too many times but nothing else happens
