I am troubleshooting a Toshiba Satellite L500D from around 2009 with AMD CPU and GPU running Win 7. When I first started the laptop, no issues.

But trying to start it a second time after a shutdown, impossible to boot up again. Tried with and without the battery, in connection power and battery and holding the power button for up to a minute, boot with the zero key pressed. I even disassembled the laptop to look for loose cable or anything out of place.

Power, battery and "on" buttons are all working but not the HDD. Screen stays black - no back light.

I left the laptop sitting for a couple of days and tried again. Laptop will boot and restart but not after shout down. When running, HDD light is working.

Any idea for I should check next?

Thanks for your help!

Let me add 2 items. First, I was able to to open the BIOS and noticed the clock was displaying the wrong date. I assumed the CMOS battery was dead or cable loose. When I disassembled the laptop, CMOS cable was loose. I soldered the cable back and checked the voltage which was at about 0,8 v. When I was able to boot and open the BIOS again, date was off again. I need a new battery but need to find one; not the standard RS2032. Can this affect the boot process?

Second, I changed the cpu-heatpipe paste. Owner was complaining about laptop becoming very hot and fan always on.

Hope this helps.
