        Sounds like you have the wrong device drivers for this computer. Check with Acer on the proper video device driver for your chipset and computer model.

        Every video chipset offers a basic compatibility to allow for generic drivers to be used for low resolution like VGA (640*480) resolution. This is why you are working ok in SAFE MODE.

        For higher resolution and higher refresh rates, special device drivers are required. Do not assume the video chipset drivers from other source will work on the box. They may have been modified specifically for this laptop model. Only use the video drivers from the manufacturer of the laptop to remain fully compatible.

            Drivers i use worked fine before the incident.

            acer driver - same
            HDMI - same.

            Well it should work fine with Display port, since it goes direct to NVIDIA.

                Originally sic631 t was soldered, i received with g manufacturer. T has floating ground on pin 4, and on g chip pin 4 is grounded.

                    Acer Predator Helios 300 - will not power up if battery is CONNECTED
                    by survivalbloke
                    This was a no power initially. Thanks to your help, I discovered it was the first mosfet, so I replaced. Now, the device will power up only if the battery is NOT connected. As soon as I connect the battery, it shuts off. If I connected the battery while the device is off, it simply will not respond to the power button. I replaced the battery, and while I suppose the new battery could be faulty, I'm assuming it is not. I'm having the same behavior with the new battery. I measure .2v at the charging coil. Manually applying power to the + and - at the battery header, there is no charging happening....

                    Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                    by Tynan Dill
                    I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                    Upon bringing it home and plugging it up, it showed a standby light.

                    I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                    The screen seems to blackout and stay black, but with a flashlight I can see the display.

                    With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                    Assuming...

                    Microsoft Surface Pro (5th gen) model 1796 - no power
                    by PantherDave
                    Hi all!

                    I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅

                    I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.
