That's usually a dead motherboard.
I take this is the 2010 model so did you try a new CMOS battery since some models hold the CPU in reset if that is dead, too low, etc.
You don't need a HDD or ODD or even RAM to get a good unit to complain either on screen or beeps. I'd try it with the following.
1. NO ODD, HDD and just one stick of RAM.
2. A new CMOS battery.
I'm going to break here for a moment that some new techs balk at popping in a dollar battery without trying more things. They are just new and the newness will wear off. You may get clients that balk at paying for the dollar battery and if you do, it's best you thank them for considering your shop and find a way to return the unit and move on to other work.
3. Now that we have the new battery in we do the usual power removed, big battery out and hold the reset for 60 seconds then release tech thing.
4. Reinstall the big battery.
Another break here. If the client tells you this battery is dead or it's missing that's a bad sign on old laptops. A bad old battery can wipe out the power section of the motherboard. The lessons over the years are used here. You stop here and call it a bad motherboard unless you get lucky and it comes back to life at the next step.
5. Apply the charger and mains power. Wait a minute for the battery to take a sip and test.
If this fails you pack it up and call it a bad motherboard. Be sure to tell them that many Core2Duo or better refurb laptops are on Groupon near the 100 dollar mark. No shop I know will do more to this old a laptop.
Hey all, I have a HP G60-635DX Win 7 and it has the typical HP black screen won't boot issue. Here's how it goes, power it up and the screen stays black ( nothing at all ) the CPU fan comes on and the hard drive spins up with the drive activity light on, caps lock light on as well as the wi-fi light, the hard drive light is for no more than 3 seconds at the max. I have tried all the tricks ( the ones I knew of and read about more) I have done : 1: Unplug/batt out and hold the power button down for 15s, 20s, 30s, 1 min and all for nothing. 2: Moved the RAM around, tried 1 stick at a time, replaced the RAM and all for nothing. 3: Pulled out everything ie- hard drive out and ram out and CMOS batt out and hold power button down to drain and all for nothing. 4: Tried a new hard drive all for nothing. 5: Left the batt out and ran on only power cable all for nothing. Now on to the ridiculous stuff. 6: Ran it for 1.5 hrs wrapped up in a blanket ( secretly hoping it would melt down but don't tell the wife lol) all for nothing. I think that's all but I could be missing something. Now, this thing has the text book HP black screen/no boot symptoms and I am really thinking something happened with the BIOS but of course at this point I'm grasping at straws and I really don't know where to go from here. I just seems like I'm missing something because it is simply the typical HP thing but the typical fixes don't work. I forgot to mention I tried hooking up a different monitor all for nothing. If anyone has any ideas could you help a poor guy out so his wife is happy coulda woulda. Thanks for reading if you got thjs far.
