Hello karwath29r. I understand that you're unable to get either of your notebooks to boot.
The flashing CAPS LOCK keys indicate an error. It will be very helpful to be able to determine which blink code you are getting. Take a look at this document and determine which blink pattern you're getting.
Let me know the result. Have an excellent weekend!

Hp pavillion dv7-3065 laptop will not turn on - led light blinks, ac's light on?
HP Pavillion dv7-3065 with Windows 7.
I fell asleep two days ago, and when I woke up yesterday, my laptop was off. (The battery very well may have died while I was sleeping, or just shut off on its own. I don't know which.) I tried turning it on, but nothing happened... except for the lightning bolt (LED light) blinking three times. No noises inside, blank screen, nothing aside those three blinks.
For the record, I've already tried removing the battery. I've also tried removing the battery, removing the AC cord, and holding in the power button for 30+ seconds. It didn't work.
I've tried removing the battery and running off AC. This still doesn't work. However, the laptop recognizes that it's plugged in; the little light by it is consistantly on. I've also tested my laptop with another AC adapter just to be safe. Nothing.
My laptop has been tested without harddrive/etc, but I'm still at a blank. I don't know what else to do. My boyfriend, who's in school to be an IT, took it into his teacher, who messed around with it, and came up with a few conclusions.
He believes that because the lights are flashing, he's confidant that my motherboard is fine. He said to replace the battery, and if that doesn't work, solder the ...I forgot what exactly, but basically it's the charging connection. I forget what exactly. My apologies there.
However... I feel like replacing the battery would be a waste of money... Because regardless of battery, the laptop should still turn on with the AC cord. My boyfriend intends to bring this up and ask if he can just skip to the other thing anyway, but he doesn't have that class again for a week, and I'm at a loss of what else to do. Aside from that, his teacher says there's a limited number of other things that could be wrong...
I was hoping to get some more input...This won't help you out, but I am experiencing the same problem... I am gonna look on this post to see if you get an answer!
I have the same problem! Except I did manage to get mine to turn on. After doing the hold the power down thing. Nothing happened. I did leave the lap top on cause I was irritated and walked away, about an hour later it came on. It let me turn it on and off a few times. Then stopped. Then leaving it sit on stopped working too -
Phone turns off and led light blinks wont turn back on
I have the 8100 and have had it for about 2 weeks I bought it off line since my old phone broke. This morning I took it off my charger and went to a meeting after the meeting I looked at my phone and the led light was blinking I hit a button and nothing happened. I then tried to turn the phone back on but nothing happened. I removed the battery waited 5 minutes then put it back in and it started to work again. But again the same thing happened. I tried this multiple times but nothing change it still went back after a few minutes. I took the battery out sim card and memory card out for an hour then put them back in and the same thing happened. Has anyone had this happen before and is there anything I can do for it. Again after I turn my phone on it "shuts off" the led light blinks like I have a message but I ca not do anything the only way to get it out of this is to remove the battery and put it back in but it reverts back to this in a few minutes. Any help would be greatly appreciated thanks
Greetings, and welcome to the BlackBerry.com Support Forums.
Leave the device to charge 2-3 hours, and then, still connected to the USB cable, remove the the battery from the device a few seconds and reinsert it. If it boots--leave it to charge to 100% (check Options > Status for the percentage).
If it doesn't boot--try using a wall outlet charger if you are not. If you are connected via USB to the PC, make certain that you have Desktop Manager (or the USB device drivers) installed, which you can download below.
Make certain your USB cable is connected to one of the PC's main rear USB ports. Not a USB hub, nor a monitor USB port, nor a USB port on the front of the PC.
Download Desktop Manager from here:

My Curve 9220 has a black screen and the LED light blinks red every 5 seconds
The phone won't come on and the light blinks red. I dont know what to do
Hi there,
If you have a good battery or the batttery is good enough then try those steps , it may help :
( Credit JSanders )
1) Make sure you have Blackberry Desktop Manager installed. BlackBerry desktop software
2) On your PC, go to Start > Run and copy and paste the following line exactly (meaning with the quotation marks):
"c:\program files\common files\research in motion\apploader\loader.exe" /nojvm
3) The Application Loader Wizard will appear -- click "Next."
4) In the "Connection:" drop-down menu, you should see "USB-PIN: UNKNOWN". Click the "Next" button.
5) You should then see a list of applications ready to be installed for your Blackberry. Hit Next and Finish and you are well on your way to getting your Blackberry back to life. Congrats! Just don't disconnect anything and let the lengthy process finish completely.
NOTE: If you do not see a list of applications mentioned in step 5 and instead see the message "The Blackberry Desktop Software does not have Blackberry Device Software for the device that you have connected to the computer. Contact your wireless service provider or system administrator," then you must download Blackberry's Operating System for your carrier and device. BlackBerry Software Download Site
Just select the appropriate carrier and network type, select your Blackberry model from the list and download the latest version. Install this download and follow the above steps again and you should be on the right path.
Good luck.

MacBook Pro won't turn on after crash. Magsafe charger LED light blinking rapidly
Hi. I hope you can help me.
I have a macbook Pro 13", from september 2012, which crashed earlier today:
I was charging my iphone through USBport on my macbook (not an Apple USB-iPhone power-cable) .
My MacBook was charging through the magsafe charger (about 30% power i think).
I took the phone out to make a call, when that was done, I reconnected the phone to my mac for further charging.
My MacBook crashed instantly. I took out the USB cable, tried to turn on my mac, but nothing happened. There was no light in the magsafe LED.
The crashing has happened before, when I've been charging my phone through USB connections, but I've always been able to turn my mac back on.
This time nothing happened when I pushed the power button. It had comepletely shorted out.
BTW. Earlier today I received a "storage almost full" warning on my mac, and I was actually in the middle of cleaning that up (deleting downloads and trash files).
Typical and just my luck!
Now, a few hours later, I tried restoring SMC (shift+ctrl+alt+power), and now the charger LED is blinking rapidly (but faintly) orange.
Do you have any ideas on how to fix this? All applestores nearby are closed today, I live in Denmark.
Thank you so much in advance!
Kind regards EmilieTry the SMC reset again:
https://support.apple.com/en-us/HT201295
Then try a NVRAM reset:
https://support.apple.com/en-us/HT204063
Then try a safe boot:
https://support.apple.com/en-us/HT201262
If no success, then you will have to take it in for service.

HP laptop G62 Blue led light blinking on the caps lock button
When booting up get a black screen. The Caps Lock blue led light is blinking once.
1: Tried a hard reset Removed battery, held down the power button for 15 seconds and tried again no luck.
2: Air cleaned the power vents around the fan same again no boot.
3: Founf the LED code chart for the blinks mine appears to blink once and a pause then blink again
the blink code chart say CPU Not Functional.
Does this mean the systemboard / motherboard is bad / fried
Thanks
EmmersondDear Customer,
Welcome and Thank you for posting your query on HP Support Forum
It looks like your Notebook has a blinking/flashing CAPSLOCK light and a blank screen all the time
Whenever the Capslock LED Blinks once that means CPU not functional and we need to replace the Processor
However, I would request with you to perform the below shown step before contacting HP
Step 01. Turn OFF the Notebook
Step 02. Un-plug the Power/AC Adapter and also remove the battery too
Step 03. Press and Hold the Power Button on the Notebook for a full minute
Step 04. Test your Notebook with Battery and Power Adapter alone
Note: If you are still facing the same issue try to remove and reseat the Memory Modules of your Notebook
Hope this helps, for any further queries reply to the post and feel free to join us again

HT1551 Apple TV Box light blinks rapidly and continously. What's the problem?
TThe light on my Apple TV blinks rapidly and continously and does not respond to the remote. What's the problem?
You'll need to use a micro USB cable. If you don't have one you can get one at most electronics store. If you have a gen 2 you'll need to disconnect everything from the Apple TV then hook up the cable and connect to iTunes.

My LED light turns on and off on its own, how can I fix this?
I dropped my phone today and my LED light on the back by the camera turns on and off randomly. I've dropped it before today and it just now started doing this. How can I fix it or do I have to bring it in to a Apple store?
The phone is probably broken. You will have to take it to an Apple store for repair or replacement.

How do i re-enable the mouse pad on my Probook ? the little LED light is on and I want it off
I just received my ProBook and I prefer to use the mouse pad... not the button ... but somehow I have engaged the mechanism that turns the pad off and the button on ( the little LED light is on in the upper left corner of the pad)
HOW DO I TURN IT OFF??Hi:
There should be user guides on your notebook's support page that will tell you how to do that.
Enter your model number in the Search Products box, and select manuals from the menu.

Hi Aparana.rahul,
The beeps during the startup of your MacBook Pro indicate that it may need to be serviced. See this article for further information -
OS X Mavericks: If you hear beeps when your computer starts up
http://support.apple.com/kb/PH14206
Note that while the article title says it is for computers running Mac OS X 10.9 Mavericks, the same information applies to other versions.
Thanks for using Apple Support Communities.

Blackberry Z10 won't turn on after software update. Black screen and LED light blinking
Im using BB Z10 (stl-100-1 ) os version 10.3.1 for 9 months, recent days it hangs a lot and it hanged later not turning on and red led has been blinking simultanously. please help me
Hi and Welcome to the Community!
Please try this sequence...note that, throughout the entire 4h15m process, your BB must remain directly connected to a known-good wall charger (not PC USB, not a cradle):
With the battery inside, connect your BB to the wall charger
Leave it alone for 2 hours, no matter what the LED or the display does
Remove the battery
Wait 15 minutes
Insert the battery
Wait another 2 hours, no matter what the LED or the display does
This has been known to "kick start" some BBs. If it fails, please do it again but increase the step 4 wait time to 2 hours, and perhaps as long as 4-5 hours.
It is also possible that your battery or BB has experienced a problem...to test, this sequence is needed:
Obtain an known good and already fully charged additional battery...use it in your BB and see what happens
Obtain access to a known good and identical BB...use your battery in it and see what happens
The results of this will indicate if it's your BB or your battery that has the problem. Note carefully please that "new" and "know good" are not necessarily the same things. While rare, a "new" battery certainly could be defective. Rather, the simplest (and least costly, btw) method to conduct this test is to find someone with an identical BB who has no issues...trade batteries and see what happens.
Good luck and let us know!

No LED light on front and black screen when trying to start up
Not sure why started my Mac just like everyday and I noticed it had frozen on start up screen was shaky but froze none the less. I tried to restart with the button on the front and nothing but the hard drive kicking in and the light on the button won't stay on like when it is up and running but will flash if you hold it and try restarting. Tried hooking up other monitor and the other monitor won't display so I don't think it is the monitor and like I said I can hear the hard drive and computer come on I just have a black screen and no lighted button on the front. Anybody have any suggestions. My iMac G3 is a 600mhz graphite running 10.4 and classic 9.2 but very rarely do I use the classic on that one as I have another just like it and they were networked together this one is fine. Help!!
iMac G3 600mhz Graphite Mac OS X (10.4.3) also runs classic 9.2Thanks but that wasn't it. I replaced the battery and reset the PMU, still no luck. I've tried hooking up an external monitor still nothing, in doing all of this the person helping and I noticed that when you push the button on front to power up it doesn't light but I'm also not getting a start up chime, only the click of the hard drive then in pushing the button to power it off the light will blink and I think it is shutting down. Any other suggestions.
Thanks
