I have a HP/Compaq 6510b laptop computer and it will not turn on...I have the charger plugged in and the only thing happening is the green light periodically flashes...Is the battery bad?


IF the battery is bad the charge lndicator on the laptop will flash (But not periodically) it will be a constant on-off-on-off..... Best check would be to remove the battery completely and use the adapter/charger power supply only. If it still does not turn on then you either have a bad power jack connection or a more serious motherboard problem. Also is the green light flashing on the adapter/charger or is it the charge/battery indicator on the laptop?

No power lights on gateway laptop model mx8711, power cord is working, does this model have a power fuse inside


Hi there.
The battery maybe faulty, remove the battery and try it on AC power only, there are no fuses that can be replaced inside the laptop.
If the laptop boots up on AC turn it back off and reinsert the battery and try to boot again, if it does not boot up then there is a problem with the battery and you will need a new one.

Good luck and thanks for using FixYa!!

Laptop won't turn on and charging light is not orange when plugge


I had the exact same problem. Here is the fix: remove the keyboard, battery and CMOS battery then press and hold the power button for a min. Plug just the power in then try to turn it back on. If it doesnt remove more perhiprels such as DVD, memory, hard drive then do the power button hold cycle again. After it turns on, remove the power then add the perhiprels you need to boot to BIOS, i.e; keyboard & memory. Go to BIOS then plug in the battery while the laptop is running. Unplug the power to see make sure laptop runs on the battery. Turn off then add the rest of perhiprels then plug it in power again before closing all up. If the orange light problem comes back repeat above! OR you can take it to your HP dealer to have it fixed under warranty if you are lucky. Then never buy HP ****!

Hope it helps...

Asus ac adapter will not wrk green light on adapter


First check the wall socket make sure you are getting power, plug a lamp into it for instance. If there is no green light on the adapter then it is bad and you will need to order a new one from your computer manufactor.

Mac Ibook Power supply problem


On Mac iBooks the orange light comes on when it charges the battery. Once the battery is charged it turns green. Im guessing the other powersupply was aftermarket or broken. EIther way, if it starts out green - recognizes the battery isnt full - turns orange for a while - then turns green when the battery is full, then the computer and powersupply are working perfectly. Enjoy your iBook!

DELL XPS M140 POWER ISSUE


Hi brendanram!

I am claudus_07 and i was a Dell - XPS Technical Support Specialist before so i will be glad to assist you with your concern.

As you said into your post, you tried plugging the AC Adapter to the power source without plugging the other end into the XPS laptop and the Green Light on the adapter is lit. But when you plug the jack on the laptop, the Green light is out. As for my experience on your laptop, there could be a problem with the power supply or the motherboard of your XPS laptop. Because everytime you plug the adapter to the laptop, the green light is going out so it means that the laptop or the adapter is grounded.

Here's what you need you to:

Step 1: Call Dell XPS Technical Support 1-800-624-9896
Step 2: Tell them the issue and the things that youve done.
Step 3: At the end of the troubleshooting, i know that the Technician will either replace the Power Supply, Motherboard, or the Adapter. (if you have a friend that has a Adapter same as yours, you may try to use it just to isolate the issue the Technician will choose from the Power Supply or the motherboard)
Step 4: If the Technician replaces the power supply and the issue still persists, call technical support again and ask them to replace the motherboard, no need to repeat the troubleshooting steps anymore just tell them that youre already done with it. (Dont ask for a system exchange, because i know that they will not give what you want.)

Thanks!
I know it will work. Be Positive!
Your good rating will be very much appreciated.

Good luck and thank you!

Latitude D505


Just repaired a laptop with the same symptoms:
Won't charge the battery, won't power from AC.
Also if you power the AC adapter when not connected to laptop you get green power LED on the adapter. When you plug it in the laptop the green power LED immediately goes out.

Opened it up and found SO-8 P-ch mosfet by the DC input socket. Source (pins1,2,3) is connected to the inner barrel (+19.5V), Gate 4 gets driven low, applying the input to the Drain. (pins 5,6,7,8) On my board the drain was short to GND. Applying power directly to the Drain via a current limited bench PSU (set 1A limit) showed a couple of volts.

Placing a finger on the opposite side of the board revealed a SMT ceramic cap getting hot.
CP13 I think. Opposite side to the power connector, almost under it. I would guess at 1206 or slightly larger and there is an 0402 cap just next to its bottom pad at 90 degrees to it. Cap was glued before soldering so had to flow both sides at the same time with a soldering iron and force off. Would likely have been 1uF or bigger 25V. Removal restored operation. Runs OK without but would suggest putting something in there 0.1uF 1206 50V, perhaps a couple stacked ?

BTW you have to strip down everything and remove the main board to get to the cap :-(

Hope this info is of use....

MY SONY LAPTOP WONT BOOT


Hi,

The flashing amber light means the screen is in power save mode. Since you are not seeing a "No Video Signal" things are looking up.

You want to use the menu buttons on your screen to navigate through and locate the power save time out settings. Its best to set it for 'never'.

If that makes the change a fix, let me know, I'll guide you through the settings on your desktop display to control the display time out.

Regards,
Worldvet
