Issue with Acer Aspire 7 laptop displaying black screen upon powering up.
Hey guys, I'm having an issue with my Acer laptop not displaying any image. Recently, it worked fine for four days, but now it shows a black screen with no Acer logo or anything. The keyboard lights up, but pressing "caps lock" doesn't show the expected "On or Off" indicator either. Can someone help me fix this?
Power supply details?
Current battery condition: age, most recent charge, temperature of the chassis.
Are there any external devices connected?
The laptop is two years old, its last charge was five days ago, and the case feels warm near the fans. It isn't linked to any external devices. The power source ID is unclear—what do you mean?
Consider passing on the model and SKU for this laptop. Turn off the device, attempt to remove the bottom cover and detach the internal battery. After that, press the power button for 30 seconds to release any remaining power. Reconnect it to your power brick (not the battery) and check if it starts up and displays properly. The thread has been moved from the Systems section to the Laptop Tech Support section.
I will attempt to disconnect the internal battery. Please give me your advice.
Edit:
I removed the battery and followed all the steps you mentioned, but it’s not working. There’s still a black screen, and connecting it to another display source doesn’t help. The external monitor also didn’t turn on.
Repeat the previous action once more, but this time include removing the ram from the laptop after disconnecting the internal battery. Hold the power button for 30 seconds to fully discharge any remaining power. For the ram, use an eraser to clean the gold contacts on the stick(s), remove any residue from the eraser, and then reinsert the stick(s). If there are two sticks, start by reseating one. Follow the power-up sequence from my earlier post. Once successful, power down and then reinsert the second ram stick.
Try this easy method, remove the battery, reset the CMOS (better to take out the CMOS battery if it’s there), then leave it without power and turn the power button on a few times.
After that, put everything back together and see if it boots. (You can skip the RAM if you prefer, I did that sometimes with this trick.)
It might not always work, but it’s worth a shot.
Reminder: If there’s a CMOS battery, replace it as an extra step. (I’ve done that too)
