Lenovo Y510p problem on BOOT

Hello everyone, I have a problem with my Lenovo y510p model, recently it started making a weird behavior when I power it on. When I try to start the machine using the normal start button sometimes it goes into the un-dusting cycle (similar to that of Energy management), it finishes it and then after few seconds I can power it on normally. Sometimes it goes into 2 or 3 consecutive un-dusting cycles before I can power it on. It's really starting to become annoying and want to know what it's doing the behavior. I tried powering the machine without HDD to see if it's a software related problem and it does the same behavior, also tried removing the second video card with the same result.

Re: Lenovo Y510p problem on BOOT

Hi Cosminc212,




First thought about how you describe it is to check the thermal cooling system including the fan.


You can try perhaps to re-apply thermal paste and clean out the fan assembly (page 60) and vents. I this does not improve the start up then you can have it further checked if there is a need for fan replacement specially booting in the BIOS or without the harddrive.


I hope this helps answer your query.

Update us how it goes.

Re: Lenovo Y510p problem on BOOT

Unfortunately re-apply thermal paste and cleaning out the fan assembly did not solve the problem, I think it might be a PCB sensor related problem. Is there a way to boot up from a USB drive with some diagnostics program like the one that tests the ram (MemTest84) but for debugging Lenovo laptops?
