Well, *****..
It's been 2 months already of my struggling with this cursed laptop. I bought Acer Aspire A715-72G-72ZR this September. Everything was fine. Then later after Windows 10 October update my BIOS automatically updated from 1.19 version to 1.28 (the latest on the website here is 1.26). My monitor started blinking. It's weird that sometimes it could take 2-3 hours up and worked properly and then started blinking again. Tried downloading manufactuter drivers, reset a hundred billion times my laptop, performed a clean installation of Windows, performed again, trying to integrate drivers to the image (interesting fact that every driver has been installed except for Integrated Intel graphics, where I've got the issue). I also tried downgrading BIOS to initial 1.19 step by step, also upgraded to the latest 1.26 available here. Nothing has helped. First month of use I used another cabel for charging it. It was 10A whereas in the box I had 7A another cabel. After this issue came up, I tried to use 7A since then. I've also got the second NVIDIA graphics. Tried to plug in another monitor which was working from dedicated graphics via HDMI. It works perfectly. After lots of clean installation my laptop now is called "desktop-..." everywhere instead of "laptop-...". Windows and Intel support directed me to Acer support, where I was told that if nothing has helped, then the problem is with hardware. Lots of service centres told me there's no issue with hardware, like I have to ask manufacturer to provide me a brand new driver. I remember initially I had a 4939 driver version (the oldest) available on the website. Tried this and also a new 5018 one. No success. Before I was asking a new driver, the support was reading my letters. Now they even don't answer me anymore for weeks. Will never ever buy anything from Acer products. Such a shame!!

Please don't post multiple threads and PMs on the same issue. It only tends to unnecessarily confuse, delay and create repeat responses. If you have a backup of the original factory-installed HDD setup, then use it to return the system to a factory fresh state. If you don't have it then contact an ACER regional service center directly to see if a USB factory recovery pendrive is available. The BIOS version you claimed was factory installed was 1.26, NOT 1.28 as suggested in your PM. Jack E/NJ

The video ribbon that threads thru the hinge area can develop conductor trace breaks than can cause these issues due to wear and tear of open/closing the lid too much. However, the more likely cause in your situation is that the video ribbon cable connectors at the mainboard and backlight inverter board at the base of the LCD need to be re-seated a half dozen or so times to clean their contacts. The fact that you get little or no flickering at the 100% brightness level suggests the backlight connections are either dirty or slightly oxidized. I don't think the flickering is caused by driver or update issues. Jack E/NJ

>>>Maybe the problem is really with backlight contacts.. >>>Yes, the connectors at the mainboard and backlight inverter board at the base of the LCD need to be re-seated a half dozen or so times to clean their contacts. The mainboard video connector is directly under the keyboard and usually held in place with only a sliding wedge. The wedge might not be fully pushed into the connector to make good contact.

>>>technician>>>said>>>Acer couldn't teach my laptop to work properly>>>If you didn't actually see the technician do it with your own eyes, I'd recommend that you at least re-seat the mainboard & inverter ends of the ribbon cable yourself to make sure it was done correctly. The technician's diagnosis should leave you with serious doubts that he actually did anything other than turn the machine on. If it was connected & working properly, flickering shouldn't occur unless screen resolution tried to be set higher than its 1080p specification limits. Jack E/NJ

Sorry. I don't know what hoax you're implying. The flickering should NOT occur unless there's a hardware failure or outdated driver. I suggest that you download and install iobit's DriverBooster freeware if you haven't done so already. If it can't find a driver online that works, then you should do a full erase everything ALT+F10 cold boot factory re-set to rule in or rule out a hardware failure and immediately turn System Protection on in Control Panel's restore point app in case it's a Win10 update that's causing the issue.

The ALT+F10 cold boot D2D method resets the machine from a hidden ACER recovery partition to the original ACER-specific Win10 version that was shipped from the factory. The ACER-specific version including the original graphic/display drivers is NOT the same system as the generic Microsoft Win10.version or the ACER driver updates on the ACER download page. If you clean installed from a USB using either Microsoft's media creation tool or a generic Microsoft iso with Rufus, the hidden recovery partition may no longer be accessible anyway. Sorry.

The hidden recovery partition is probably still there. If you open diskmgmt.msc you will probably see two recovery partitions. One is for the original ACER partition. The other is for the generic version you installed. If you only see one recovery partition, then the generic Win10 installations have likely overwritten the original ACER partition. Despite what your technician friend seems to claim about there being no hardware issue, probably the best and quickest way to rule out a hardware issue is with the original ACER version of the Win10 system files along with the drivers that are supposed to work with this ACER version.
