Y460P won't boot

2012-06-20, 10:23 AM

So, I've been messing with my laptop far too much I'm afraid it's beyond repair but well, here goes

I flashed my Y460P with an unlocked bios with normal procedure and everything seems to went well

I didn't have chance to boot to windows after the flash since after reboot I went directly to bios setting (it started up..)

Altered a few settings which I can't recall exactly what but I guess they were:

- Enable Intel IGD

- Setting CPU temp limit to 100

I think those are the only things I altered...

Then F10, reboot

 

The Y460P has this slidenav thingy on the keyboard that has strings of LEDs that would lit up from left to right on boot,

Well, after I power on my laptop, the LED start up normally, then it freezes just like that

Screen has light but blank

Only bluetooth LED lits up, no HDD, WLAN LED

If I insert a bootable USB, it doesn't get read at all, no flash LED from USB

CTRL ALT Del doesn't even reboot

 

So I went a bit crazy and did something more

I opened up the cover and removed the CMOS battery, left it out like 20mins then put it back hoping a CMOS reset would help (well, I did try to power it on while the CMOS battery is off but the result is the same as below)

Now it acts very weird

When I press the power button, the LEDs lit up for a very short time then off for like 5seconds of no power

Then it would power on again and follow the symptom above

If I press the power button again during the 5 secs of no power, it seems to just repeat again

 

I tried all recovery for the BIOS, Fn+R, Fn+B, hold power for 60 secs and none seems to work

The USB doesn't flash at all

 

Any help would be appreciated, I would hate to have to bring it to service center

A mess I've created I know

Thanks in advance

By Unlocked BIOS, do you mean someones modded version?

Sounds like you have tried some recovery, but I feel a service
center is the only hope. My Opinion.

Hi,

It seems very similar to my problem.

The laptop semms to turn on, but freezes before enabling the Boot Sequence.

No Hard Drive activity, Completely Dark Screen.

I tried to plug an external Monitor, It is not the screen.

I will try tomorrow to replace Hard Drive, But i am afraid it is the Mother Board.

It all started when Monitor started to flash Horizontal and vertical lines, then Both and then Monitor was out.

It started fine a couple of times after reboot but did the same after a few minutes untill now where it just freezes right away.

Did anybody have similar experience? Did anyone figure it out, I am curious.
