HP Spectre 13 ultrabook - fuse location for monitor backlight

[aelk5579]

Hi,

I have a HP spectre 13 which 2 days ago for no apparent reason just had the backlight fail. I can barely make out the monitor as there is no backlight

The screen has been changed and still the same issue so it most likely is the backlight fuse that has gone out. Problem is I am having troubles finding a diagram of the motherboard for this model (13-v000 series) so cannot locate the fuse

Would anyone be able to point me in the right direction?

Thanks

Thank you for posting on the HP Support Community.

• When was the last time it worked without these issues?
• Have you updated Graphics and Chipset drivers?
• Have you checked the display on an external monitor?
• Did you check with the store where the computer was purchased?

let’s try these steps to resolve the problem:

I recommend you attempt to access the BIOS screen by tapping on F10 while the computer is restarting, 

If the issue persists in the BIOS screen which is outside windows, it would confirm a hardware failure and computer needs to be serviced.

Hope this helps! Keep me posted for further assistance.

Hi,

Thanks for your response. The last time it worked was last week. I had the notebook on and was doing work.. put it down and the screen went to sleep. A few minutes later tried to wake up the screen and it wouldn't come back

After several minutes I realised there is an issue.

The issue is hardware related as it persists in the BIOS scree.

I have updated all the graphics and chipset drivers. Yes I checked with an external monitor and it displays fine

I asked the shop I purchased it from and they could not help as it is out of warranty

The system board model is BSE30 LA-D401P and HP product ID is 854753-601

Computer product ID is w2k26UA

I am looking for the service manual or diagram of the system board to show me where the LED backlight fuse is located

If you can provide this to me it would be appreciated.

Or if HP can provide the system board bdv file so I can open it up in board viewer it would be even better

Thanks for your help

Hi

Thanks for your reply. The service manual you provided helper me disassemble the computer and remove the system board which I did safely

Unfortunately without the system board diagram, I am unable to determine where the backlight fuse is located 

I also looked on laptop-schematics and couldn’t find the schematic for my board 

thanks for your help

I have the same question!
On the laptop motherboard a backlight chip needs replacing but which one it is...who can tell?
Has anyone done the repair before?
