Yesterday after using my laptop and noticing it was kind of overheating I decided to turn it off. But since I forgot to do something I decided to turn it on again(it was still kind of hot).

When I turn it on I notice the screen is still black after a few seconds, but I thought it was only taking long to load, but then the windows welcome sound is heard. Which means it started up. On the other hand, the touch panel it has on the bottom is on, so is the little light the CAPS key has. I´ve tried restarting and many other methods which I found(which for some reason include the battery) but the screen is still all black, although the system is running up.

It an HP Pavilon dv4-2012
It runs Windows 7

Given 's symptoms — the machine sounds like it boots (Windows sound) and lights come on while the LCD stays black — the fastest way to narrow the fault is to decide if the laptop is actually outputting video or if the internal display/backlight/cable is failing.

First, try simple, non‑invasive checks: attach an external monitor (VGA or HDMI) and see if the desktop appears. If the external shows the desktop, the GPU and OS are fine and the fault is inside the lid (panel, backlight or LVDS/eDP cable). If the external is also blank, suspect the graphics/motherboard or firmware. Next, boot with the lid closed/open and use the brightness Fn key to rule out a dimming key. Also do a power‑drain: remove AC and battery, hold power for 15–30 seconds, reconnect AC only and boot.

A quick in‑place test for backlight vs. LCD: with the machine powered and apparently booted, shine a bright flashlight at the screen at an angle. A very faint image means the LCD is working but the backlight/inverter (or LED driver) has failed; a totally dark screen with no faint image and a working external monitor points to the panel itself or a cable/connector fault. If comfortable opening the bezel, check the flat display cable where it passes through the hinge and at the cabinet connector — look for pinched, frayed, or loose ends. Always unplug AC and the main battery before disassembly and ground yourself; the display connector is delicate.

Given the reported overheating and 's similar melt example, inspect for heat damage or melted insulation near the hinge. If a connector or wire looks burnt, stop and seek professional repair. If still under warranty, use manufacturer support as suggested; otherwise replacing the cable or panel is a common, straightforward repair for technicians or experienced DIYers (identify the panel part number on the sticker before ordering).

Hello,

Try . Try the link provided it's from HP, if you recently bought the laptop and is still under warranty they should fix it.

- Let us know how it goes.

Thanks, but the warranty finishes like 6 months ago lol.

I think the problem is just the cable that connects the screen(forgot name) with everything else. I might fix that myself.

Thanks.

I can't be too sure about this issue, but have experienced something similar on an Acer laptop which resulted in the screen not functioning.

It overheated and the screen stopped working completely. Turns out it was an important wire that connected to the display that had melted or detatched or something.
