When I opened my laptop this morning my computer won't come on. The screen is totally black. I took out the battery and put it back in ---- still nothing. I plugged it in with the power cord --- nothing! What is wrong with my HP Compaq Presario CQ60?
suspected hard disk faulty or OS corrupted.
to check, take out your hard disk and put it in other laptop. if the problem persist your OS is corrupted. In that case, you need to reformat your OS in a defaulty factory settings.
have you any other A/V ports out ie Svid etc if so try that via an A/V lead, if that works reset your bios settings to minimal settings, if that doesnt work search the 'net someone somewhere has had the same problem! try shining a flashlight/lamp onto the screen whilst booting up, if you see anything on the screen then your inverter is definatly gone and yes it could still be your inverter! your laptop may have software/hardware issues with an external monitor?
1. Remove all USB devices such as printers, mp3 players etc etc.
2. Remove the power-cable and the battery
3. Press and hold the power button for 30 seconds
4. Put the power-cable back in but not the battery and none the USB devices.
5. Turn the computer on
Sounds like the auto-dim in the BIOS is set too low. Fortunately the Compaq R3000 allows you to adjust the brightness right from the keyboard. Hold down the [FN] function key while tapping the [F8] key will brighten the screen, while [FN]-[F7] will dim it. The settings are different for running on AC power and battery, so you must do each individually.
It appears without looking at the laptop you have removed or dislogged the cable that goes between the motherboard and the screen. This is not hard to do they are very delicate. The only thing you can do is take it to a qualified service tech. i get these periodically in my shop too. Check the cable before you do so to see if you can reconnect it but be very carefull.

It sounds like you have fried motherboard. If that's the case, you have to get it serviced by a place your manufacturer recommends. Sometimes the cost can be greater than just buying a new laptop, so shop around and see what you can find price-wise.
It is possible that while you had it apart you lossened one of the IDE ribbon cables from the motherboard or harddrive.Take it back aprt and make sure all the cables are tightly seated.Rate me FIXYA! if this works!
