HomeIn this tutorial I’ll explain how to remove LCD screen and replace inverter board in an Acer Aspire 5100 laptop. This tutorial will work for many other Acer laptops with the same body.
In my previous article I was taking an Acer Aspire 5100 apart.
OK, let’s get inside the display assembly.
First of all, turn off the laptop, unplug AC adapter and remove the battery.
The screen bezel has four screws hidden under for seals. Two rubber seals on the top of the bezel and two plastic seals on the bottom.
You can remove all four screw seals with a sharp object as it shown on the picture below. Glue removed seals somewhere on the bezel so they don’t get lost.
Remove four screws found under seals.
Start remove the screen bezel with your fingers. Proceed slowly while removing the bezel.
Continue removing the screen bezel.
The bezel has been removed.
The inverter board is mounted below the laptop screen. If you are replacing the inverter board, you’ll have to separate the top cover from the screen first.
Remove four screws. Two of them securing display hinges and other two securing the inverter board.
Carefully separate the display cover from the screen and access the LCD cable connector.
You’ll have to unplug the LCD cable from the screen.
First, unglue the clear sticky tape securing the connection.
Second, unplug the LCD cable from the connector on the screen.
Now you can access the inverter board witch is still connected to the laptop by cables on both sides.
Carefully unplug cables from both sides of the inverter board.
Remove the screen inverter board and replace it with a new inverter.
Here’s how you can remove the LCD screen.
Simply remove four screws securing the LCD screen to the display hinge. Remove four more screws from the other side of the screen.
Now you can remove and replace the failed or cracked screen with a new LCD screen.

Michelle,
.
If I understand correctly the LCD screen is broken. Will it light up at all when you turn on the laptop? If it does, the inverter works properly. All you need is a new screen.

Steve,
Could be bad memory module and poor connection between the memory module and motherboard.
Try reconnecting memory. If you have two modules installed test the laptop with each memory module separately. Install memory one by one in each slot and test.

I have an Acer 5100. One day (after my 14 year old had it) the screen came up looking as if it had been smashed. I’ve been using my laptop by connecting it to a stand alone monitor. How can I tell if I have to replace something else other than the monitor? How do I know if I need to replace the inverter board?

Hello Laptop tech,
I am working on an acer 5100 for a friend. It appears to not boot at all. Power LED is on, fan is on, hard drive light flashes for a few seconds but does not come on after, and the display stays black. Also, pressing the caps lock or num lock keys don’t cause the LED’s to illuminate. I fear this is a CPU issue, but am not sure how to test this. I removed the bottom covers and cleaned a fair amount of dust from the fan, vents, and heat sink. Afterwords, the laptop powered up and was working, but quit after it was given back to the owner. Any ideas would be greatly appreciated.

Hi, I got my husband an Acer 2 years ago. About a year ago the mouse pad stopped working. My husband was skeptical and didn’t want me to try and fix it so he got a wired mouse. We recently the computer started acting funny. Not wanting to come on, etc. Well 3 days ago I was online and they screen just went blank then all these lines came up on it. I shut it off and it wouldn’t come on. I removed the battery and teh lights came on but then it started making a loud noise. After that i removed the battery again and it worked fine. Once we cut it off it comes on but the screen is blank now. What could this possibly be?

Does anyone know what the little switch right to the cable connector on the mainboard is for?
thanks

Don H,
It’s hard to tell without testing the laptop with another known good inverter board and you’ll have to guess. From my experience, inverter board failures are more common than backlight lamp failures. It’s way easier to replace the inverter board than backlight lamp.
I would try replacing the inverter board first.
Also, check the lid close switch. Make sure it’s not stuck inside the case. When the switch is pressed down, the laptop “thinks” the display is closes and there is no power coming to the inverter/backlight.
I guess you can find the part number somewhere on the inverter board. Access the inverter and google any number strings you can find on it. I don’t know the exact part number.

Dear Laptop Tech,
I have an Acer 5100 that works fine attached to a standalone monitor but the primary LCD does not work. When I boot I see faint lighting of the screen and I can also see (faintly) the irritating Windows messages from the system tray. I’d like to fix it and am guessing Inverter or LCD, can you make any recommendation about what to fix first?
Also, is there a place to find the exact part numbers for those items? The machine is an Acer Aspire 5100 manufactured in December 2006.
Thanks so much,
Don H

Tracey Cyr,
That’s a BSOD (Blue Screen of Death) error.
I think in your case that could be a memory related problem. Apparently one of the memory modules went south and because of that the laptop will not turn on.
Here’s what you can try.
Most likely you have two memory modules installed into your laptop. Both modules can be accessed from the bottom of the laptop as you can see in this tutorial I posted before: Taking apart Acer Aspire 5100 laptop.
Try removing memory modules one by one and test the laptop with each module separately. If the laptop starts fine with one module but not with the other, the second one is bad.
You can run the laptop with one working module until you find a replacement for the second one.
