    Try reseating the memory one stick at a time in each slot one at a time and try turning on the laptop with each stick you reseat to make sure its not a problem with the memory being dirty or a bad stick of memory.

Try and hook up an external monitor you may have to switch to external on the keyboard with the fn key and the one that has the tv picture on it usually f2. If you can see a picture on the external then either the invertor or the backlight is damaged if no picture on the external then the video card or video circuit on the motherboard is shot. Also try hitting the esc key or f2 key to get into the bios at boot if you see a bios screen then the problem lies elswhere.

My compaq presario cq60 wont turn on


Does the laptop boot? Sound? Do you see a "ghost Image" in the monitor in a bright light? If so, Could be backlighting, Inverter, on/off switch that shuts the monitor on/off when you open and close the lid. Can you boot to safe mode with networking? If so, Open the Device Manager, Uninstall the Graphics Adapter, reboot, the software will apply a generic driver, If the Graphics adapter has not failed completely.

Compaq Presario laptop C300 - issues (orange light)


Sometimes when a PC gets stuck in hibernation mode, the only way to reset it is to remove the CMOS battery for 10 minutes and replacing it. It resembles a large watch battery and is usually located near the center of the motherboard.

Compaq CQ50 laptop powers on, but does not boot. Black Screen Lights on keyboard, lights on power jack port. White power light is on the power button. Fan Runs and the DVD runs but no response from DVD. No...


I'd try messing with the memory. Try booting one single stick in each of the slots.

I've noticed that this happens pretty frequently with certain hp / compaq models.

If you've already tried that you can try removing the cmos battery for 5 minutes but aside from that the motherboard has probably gone out :(

I hope it's under warranty!
