L440 occasionally won't boot. 5 times beep code

2016-08-06, 16:59 PM



I need help troubleshooting the Thinkpad l440 of my roommate. Whenever she turns the notebook on, the screen remains black and a repeating error beep code is audible. 5 beeps then pause and another 5 beeps and pause and so on.

Most of the time after some second oder even minutes it continues booting normaly and the OS (Win7 64bit) start up perfectly normal.


Since the notbook isn't the newest modell and no waranty left, repairing in by lenovo service wont pay off.

I already checked a number of things including CMOS Battery, lose flat-flex connectors, Ram etc.

Than i tried to Update the bios via lenovo's utility through the OS .. this did not work with an errormessage telling me the bios could not be read.

Now I want to do it via CD. What do you think .. might that help. or is the risk of comlpletely blowing up the machine to high in case the system cannot restart properly after updating the bios?


We would be truelly grateful for some information or advices.

Thanks in advance.
