W500: Sometimes boots, sometimes doesn't (hangs at Lenovo screen)

Hello!

 

I have problems with my W500. It sometimes boots, and sometimes not.

It literally is random, and I have no idea why.

 

The times it doesn't boot, it hangs right after the press on the power button, when the "Lenovo Thinkpad" screen appears. It just does nothing.

It doesn't react on keyboard presses. I waited on this screen sometimes for hours.

If I am lucky after several minutes it finally boots. Sometimes it boots right away, without problems.

 

The BIOS software got updated by me yesterday, but it didn't change the problem. There are no devices connected to the Thinkpad that could cause that problem (no usb drives, no network cable, ...). 

 

The USB ports seem to be fine (this is one of the solutions that people are given when encountering my problem).

 

I hope someone can give me recommendations on what do do or what could be broken.

 

Thanks in advance,

czenjio

I will assume you are not doing something unusual, like a network boot and that you are not normally connected to a domain controller for security. Something is timing out. It is probably just a motherboard problem, but there are things to try. Pull the optical drive. Then, I would first, disable all the optional devices in the BIOS. You can see them by looking at the security tab and choosing I-O port access. If that fixes things, add them back one or two at a time to see when it gets sick. Please note, there are lots of parts that connect as USB devices, such as the internal keyboard, touchpad, Bluetooth, camera, etc.

Hello richk,

 

you're right, I'm not trying to do something unusual, it's a normal boot without any abnormalties.

 

The removal of the optical drive didn't result in solving the problem (would be funny though), and unfortunally I can't get into the BIOS because the device doesn't react when pressing keys on the keyboard.

 

You said "It's probably _just_ a motherboard problem", but isn't that the worst that could happen? I mean something like a broken RAM you could easilly replace, but a motherboard is kind of stressful and expensive. Sorry if I am missunderstanding you! Smiley Happy

 

Really? The internal keyboard etc. get's recognized as USB devices? That's interesting!

The internal keyboard should be PS/2.

Are there any damaged USB ports? Or rather, anything stuck in any USB ports that could spontaneously bridge contacts?

I don't see abnormalities compared to the other ports, I don't think one of them is broken (or all of them).

It might also be an iffy keyboard or keyboard cable. Try reseating the keyboard maybe?

I did several times, this should not be the problem, unfortunally. :/

 

Also, the times it does work, the keyboard also did (I don't know if that means that the keyboard isn't the problem).

What if you take out all the sticks of RAM and try booting it? It should error out with a 1-3-3-1 beep sequence.

When I said "just a motherboard problem", I didn't mean that was the one to hope for. When you look at the problem, the motherboard is the part that someone would guess first. I was looking for something that you could fix without needing a MB

Re: W500: Sometimes boots, sometimes doesn't (hangs at Lenovo screen)

I tried that, and without RAM sticks inside it doesn't even show anything on the screen, not even a beep sequence.

What's kind of weird is that when I tried it yesterday, the Thinkpad booted (I tried 2 times to be sure).

I thought that might be the solution (to reseat the RAM), but today it doesn't work anymore.

 

It seems like every time I screw the screws back in and reassemble my Thinkpad, it doesn't boot anymore. But I don't screw them in like a wrestler or something, I am careful. I don't think this has anything to do with it, but I just wanted to leave it here.
Might aswell just stop working after couple of hours (in my case half-a-day).
