Acer warranty void stickers and screen flickering

SAUCY

I opened my laptop to clean it because there was an ant infestation. Six months later, my screen started flickering. I still have time to use the warranty. Am I disqualified from the warranty because I opened my laptop? Also, the flickering only occurs on the laptop screen, not on the monitor I recently bought.

Regarding warrant-

Removing the warranty void sticker if available on Acer laptops can lead to confusion regarding warranty status. Generally, the consensus is that breaking the sticker itself does not automatically void the warranty, as long as no damage is done during the process of upgrading or repairing the laptop.

Many users have reported that customer support representatives have confirmed that the warranty remains intact if the device is not damaged during upgrades or cleaning or thermal pasting, despite the presence of the sticker. However, this can vary by region and specific circumstances, so it's advisable to contact Acer customer support directly for clarification based on your location and model. Use below link and contact them through email or online chat/call-

Regarding screen flickering-

First, check if the flickering issue is also occurring in the BIOS. If it is, the flickering may be caused by a faulty GPU, display cable, or monitor. This issue is typically covered under warranty.

In your case, I suspect that the DisplayPort (DP) cable might be the problem. If it is under warranty, it can be easily fixed at no cost. If it is not under warranty, the repair should still be reasonably priced.

Regarding the faulty GPU, if your laptop is under warranty, it is beneficial because they can repair it at no charge. However, if it is not under warranty, it may not be cost-effective to repair the GPU. In that case, purchasing a new machine could be advisable.

You have to visit Acer service center for diagnosis and repair.

Screen flickering in Windows 11 is usually caused by a display driver issue or incompatible app. To determine whether a display driver or app is causing the problem, check to see if Task Manager flickers. Then, based on that information, you'll need to update, rollback, or uninstall your display driver or update or uninstall the app.

Press Ctrl + Alt + Delete to open Task Manager. If you don’t see Task Manager after pressing Ctrl + Alt + Delete, press Ctrl + Shift + Esc to open Task Manager.

If Task Manager flickers along with everything else on the screen, a display driver is probably causing the problem. In this scenario, see the Fix your display driver section.

If Task Manager doesn't flicker while the rest of the screen is flickering, an incompatible app is probably causing the problem. In this scenario, see the Update or uninstall an incompatible app section.

If Windows Update recently made updates to your device, roll back your display driver. Otherwise, try updating or uninstalling your display driver to fix the flickering or scrambling problem.

Roll back your display driver

In the search box on the taskbar, enter device manager, and then select it from the list of results.

Select the arrow to expand Display adapters.

Under Display adapters, right-click the adapter, then select Properties.

Select the Driver tab, and then select Roll Back Driver > Yes.

Restart your device..

Update your display driver

In the search box on the taskbar, enter device manager, and then select it from the list of results.

Select the arrow to expand Display adapters.

Under Display Adapters, right-click the adapter, then select Update driver.
