If you landed on this page then you definitely have a problem with an iLife ZED Air pro or any other series of the iLife notebooks. What happened?
Ok! So you tried making some BIOS changes for your laptop and after saving your settings, keyboard stopped responding, touch pad is no longer working, you are unable to enter BIOS settings as well.
It is quiet annoying when this thing first happened to me. I looked for solutions online for a whole week and non of the solutions online was close to helping. I was so pissed I felt like breaking the laptop into pieces and giving it a new resting place in the garbage can. Then I realized I have not taken time to diagnose the problem by myself. I asked myself some few questions.
Why is the keyboard and touch-pad not working?
The keyboard stopped working because of a change I made to the BIOS settings and saved it. Any change that you save in the BIOS settings is not saved in the computer memory but rather, to the BIOS chip of the computer.
How do you reset the BIOS?
You can simply reset the BIOS by simply cutting all powers that help the BIOS chip store its data. One of the most common way most computer manufacturers power the BIOS is to use CMOS battery which saves and stores the BIOS data.
Then comes another problem. The iLife ZED Air Pro G I was trying to reset the BIOS for is more like a tablet than a laptop. It is a full tablet. No processor fans, no CMOS battery and it is powered by a battery which is charged by 5V DC adapter.
Disconnecting the main battery from the motherboard didn’t give it any effect after I turned it on. Then I decided to use what is called;
Brute Force BIOS Reset
This is highly technical so if you are not technically inclined, don’t try this. Also opening the laptop at the first place will void your warranty so it is highly recommended that if you are experiencing problems with your laptop, you send it to manufacturer’s service center for proper fixing and to save yourself some money.
In resetting the BIOS chip with brute force, you will need tweezers, screw driver or even a pocket knife will do.
Locate the BIOS chip on the board. With mine, I was using iLife ZED Air Pro G and it has two BIOS chip. The main chip and a backup one but I couldn’t tell which one is the main chip and which one is the backup one so I decided to try with only one of them.
This is how you go about it.
After locating the BIOS chip, locate pins 1234 and bridge with the tweezers, screwdriver or pocket knife. To be on the safer side, let the power off, disconnect the battery, disconnect the charger before you do that and after bridge, press and hold the power button for 1 minute.
Fix battery back and power the laptop. Press your keys to see if it will work. If it didn’t work, repeat the steps again this time around, bridge pins “5678” if this didn’t work as well, then you should locate the other BIOS chip and do the same thing. Hopefully one of them will work.
That is how I did mine and it was working fine after.
I hope this tutorial will help somebody solve their problem.
