I just bought a used thinkpad l430 a few days ago, in great condition, almost no cosmetic defects that would indicate any issues with the laptop. today, I started to get a black screen when turning it on, accompanied by a series of 1-3-3-1 short beeps. according to some other posts and bios documentation, this beep sequence indicates a motherboard or ram issue. however, I was able to get the pc to start up after removing the battery and removing the ac adapter a few times. just now the same thing happened again, this time I also had to do the same switcharoo between running the machine on ac power and battery, and taking the battery out periodically. once I get it to start up, everything runs fine, however, the whole routine that I now have to do to get it to boot is a big waste of time.
does anybody know what the issue could be here? at first I thought it was the battery, but it didn't turn on the first time I removed it, only after I removed it a few times. neither is it the ac adapter for the same reason, I can't imagine how it could be motherboard or ram if it runs fine when it finally starts up. I like this computer and I don't want to return it as there is still a warranty on it but not knowing whether it can be solved by replacing something is killing me...

Welcome to the forum!
according to some other posts and bios documentation, this beep sequence indicates a motherboard or ram issue.
That's correct. I would first check that the RAM is ok by booting from a USB/DVD drive with MemTest86.
Alternatively you can also check that the RAM modules are properly inserted in the slots, and clean the slots with compressed air and the RAM contacts with 100% alcohol.

Hi! Welcome to the forum!
That beep sequence is normally a RAM or motherboard problem. Try the following:
Remove the AC, battery, RAM, WLAN card, WWAN card (if installed) and hard drive. To do this follow the instructions of the maintenance manual (click me, chapter 9)
Put back one of the RAM modules in one of the slots and try to boot, if you still get the 1-3-3-1 beeps, try alternating RAM modules in different RAM slots (provided you have two RAM sticks).
If your L430 boots, make sure to go into the BIOS, load up the defaults (press F9) and save (F10).
Please report here the results... :-)

Or maybe it was faulty to start with and the old BIOS version wasn’t detecting the problem?
That could be one of the reasons, or maybe the RAM just went south at the same time you updated the BIOS, but that would be an awkward coincidence
You can try cleaning the RAM slot on the motherboard using compressed air, or clean the RAM contacts with 100% alcohol or a pen eraser.
Was it one of the modules oringally shipped with the L430? What brand is it?
