You may have found yourself here through a Google search because you have an IBM Lenovo T60 that will not boot up (appears dead) and has a sequence of 4×4 beeps (four sets of four beeps).
The symptoms are:
– 4 sets of 4 short beeps
– Nothing on screen
– No access to BIOS
This is what I did to fix my problem:
There was a lot of talk on the Internet through searches about it being a problem with the security chip on the motherboard and the motherboard being toast. Fortunately I ploughed on and was able to fix it without throwing the machine away.
First of all, I reseated the RAM as four beeps ‘could’ be RAM related. This did not help and the fault remained.
I then decided to do what I would do with any PC which is reset the BIOS and get everything back to basics.
To reset the BIOS, follow these steps:
– Unplug the AC mains adaptor.
– Take out the main battery.
– Take out the CMOS battery as shown in this video
– With no power (mains, battery, CMOS battery) press the power button 10 times and on the 11th press, hold it down for 30 seconds.
– Reconnect the CMOS battery.
– Insert the main battery.
– Reconnect the AC mains adaptor.
– Press the power button to start the laptop.
– Enter BIOS by pressing the blue ‘ThinkVantage’ button and correct al lthe settings you need to.
This worked for me, I hope it helps you! If it did, click below and buy me a coffee!
