T500 not turning on when pressing power button...

2009-12-24, 16:55 PM

I just got a T500 and when I go press the power button, the circle with the "z" lights up but the T500 does not boot. I have to press and hold the power button to get it out of this state, the press and hold the power button to boot the machine. Any idea why it goes in to this "sleep" mode instead of booting?

Are there any other lights on?

 

"Z" means that it's turned on. Maybe connect an external monitor?

 

If you just got it support is a good place to go, especially if it doesn't boot!

Hello,

The blue tooth light is on and the battery light goes on (I usually have it unplugged). But this no booting hting still happens when plugged in.

@smeat2000:

It looks like a damaged battery.

 

 

@sunilmanickalal

Please first read until end of this posting ;)

 

In many cases contact of the keyboard and/or the electronic parts inside the notebook with liquids can cause these problems.

In that case you can see the trace on the system board (colored veil).

 

In other cases a damaged system battery can cause the same problem. - try to turn on without battery.

 

Sometimes after a BIOS - update you learn a strange behavior. - Go into BIOS, press F9 (load defaults), F10 - yes and turn off computer after the display backlight turned off.

If it does not help, pull the BIOS battery for a few minutes. If BIOS paswords had been set, you'll need the supervicor password to boot.

 

Last but not least a hardware component may be damaged:

- Wireless Lan/Wan

- Bluetooth daughtercard

- hard disk

- optical ultrabay device

- USB-connector

- possible attached external devices

- keyboard (if you have a dock, start with the power-button of the dock after detaching the keyboard)

 

have success

If the battery is bad, remove it, and connect the A/C adapter w/o the battery.  If the battery was the problem, it should now boot OK.
