U530 Touch - Laptop won't turn on

Machine: Lenovo IdeaPad U530 Touch

 

Symptoms: pushing the power button turns the computer on for approximately 1 second.  Power button lights, backlit keyboard lights, fan starts up, then after one second, everything turns off.  When plugged in, the battery light is lit.

 

What I've already tried:

* The magic code - unplug adapter, disconnect the battery and press the power button 10 times, then hold it for 60 seconds. Then restart as normal.

* Leaving it plugged in for a day.

* Leaving it unplugged for a month.

* Reseat the RAM

* Replace the RAM with known working stick.

* Removing the RAM completely.

* Reseat the hard drive.

* Replace the hard drive with a HD from another Lenovo laptop.

* Removing the HD completely.

* Reseat the display cable where it connects to MB.

* Hold down enter while hitting the power button

* Tilting the laptop 45° while hitting the power button.

*Praying and offering to never look at porn again if it would just boot.

 

None of these had any effect.  Exact same process every time: powers on for one second, then powers off.

 

I've smelled the MB for any signs of fried components.  Nothing.  Everything looks good on the inside.

 

Possibly related: before this, I was having terrible times with the boot process.  System would take forever to boot, then blue screen, saying there was a problem and the system would reboot for me, then it would reboot as normal and everything would be fine.  Entire process took about 10 minutes though, and happened every time I shut the machine down. Before I could dedicate a Saturday to reinstalling Windows 10, this problem started.  That may be irrelevant at this point, but thought I'd mention it just in case.

 

Anyone have any ideas of something else I could try to diagnose the problem? Or is it time to just chalk it up as a dead MB?  I feel like it's something simple, but can't figure it out.

Re: Laptop won't turn on

Hello Jsfrench,

Thanks for using the Lenovo forums.

Try to see if you have any recovery media, if you are able to install an older OS on the unit, I had something similar happen, but in my case, the unit would not boot after trying to install Win 7 on it, Win 8.1 seemed to have fixed it.

 

Otherwise, by the sound of things you pretty much tried everything, including prayers Smiley Very Happy

 

 If these steps do not work you can call your local Lenovo support line for a potential repair. Below is the link to the phone list where you can find these numbers

 

Hope this helps, let us know how you get on.

Re: Laptop won't turn on

Welcome to the Lenovo Community Jsfrench !

 

It sounds like you did a pretty thorough trial and error examination.  A couple of other things I would try is to disconnect the LAN/Wireless card.  A faulty card may prevent boot up.  I would also try disconnecting the USB board.  A bad board may also prevent boot up.  You can just unplug that for testing, no need to fully remove.  Your model's Hardware Maintenance Manual will explain how to remove those items if needed.  Here is a link to that manual just in case you haven't viewed it yet.....

While inside the laptop I would also check to see that the cooling fan is moving freely.  A stuck fan may prevent boot up.  I would also check all the connections to insure they are secure. 

 

Last, but not least try doing a hard reset of the CMOS.  This can be done by disconnecting the charger / adapter along with removing the main battery.  Then disconnect the round coin cell battery that is plugged into the motherboard.  The battery should be covered in black vinyl and will have a red and black wire coming from it.  Once this battery is disconnected then press and hold the power button for 15 seconds.  Then re-install both batteries, plug in the charger / adapter if needed and see if the laptop will now boot.

 

If you have tried all the above and the problem remains then there isn't much else left, but the motherboard.
