Compaq CQ61 won't boot, 2 led blinks.

Product Name and NumberCompaq Presario CQ61-310SA Operating System installed (if applicable)None Error message (if any)LED flashes twice before pausing and repeating. Indicates BIOS corruption. Any changes made to your system before the issue occuredBeen inactive for 10 months due to having no power cable, I purchased a 3rd party power cable for it today. ProblemHello, as I stated above, my laptop has been inactive for 10 months and only today I decided to finally get a charger for it, which set me back £5.99, clearly a low quality charger but I was unsure if the laptop even worked anymore and didn't want to splash out on a manufacturer charger. When the AC adapter is plugged in, the LED indicator next to the charger port lights up, but with the battery installed the charge LED inbetween the Power and HDD LED's flashes 4 times, on the 4th flash it holds for about a second then discontinues the blinks. When powered up the backlight and LCD do not turn on and the CAPS LOCK and NUM LOCK LED's flash twice before pausing and repeating and the WiFi light glows orange. I can hear the HDD and fan spinning but the BIOS isn't initiated. I understand this error code refers to BIOS corruption and have attempted a hard reset, holding the power for 15 seconds as stated on some websites, then 30 as stated on others, and finally 60 seconds, as well as replacing the BIOS battery, HDD and memory modules to no avail... It doesn't seem as if the battery is charging at all, but it is completely empty so I'll leave it for a while to see if it does charge. Is this anything to do with the fact I bought a cheap chinese charger? Or would I have to replace the motherboard? AC AdapterName: WeiXin Da Electronics AC Adapter - PA-1700-02Input: 100-240v ~ 1.8AOuput: 18.5V ~ 3.5A Many thanks, Jordan.

This is a phenomenon of these computers.
If you have a computer that won't boot, remove battery, unplug charger. Press powerbutton for at least 20 seconds, insert the power cable, and hold for another 20 seconds. Nothing will seem to happen. Then press power again.
Your LiION battery is close to end of life. Replace. Or get used to doing this. Diag software will warn for failed battery. You will also have a ton of BIOS messages about an obscure error occuring. But you need to have a working Diag partition to make some sense of the meaningless error reported in BIOS.
This has nothing to do with the RTC/NVRAM backup. But it's no reason to not replace it. It costs about 3$ and you can find a 2032 Lithium cell almost everywhere. (3V, 20mm diameter, 3,2mm thick). Located under the harddrive bay cover on the bottom of computer.
If no boot occurs, check that the "lid closed" switch is working. In some environments they can get stucked in "Lid closed" position.
Also if you have access to a can of compressed air (duster), clean the airflow / cooling part from accumulated dust.
These are not exactly the most energy saving computers. They get hot. I have seen examples of plastic chassie parts melting.

BlackBerry Curve 8330 won't boot, LED blinks and hourglass spins

I bought this pink BlackBerry Curve 8330 in December of 2008. It has worked perfectly since and I've never gotten it wet. It's been dropped 4-5 times, but never from more than 3 feet.
This afternoon, in the middle of writing a text, it suddenly powered off and the red LED light came on like it does when it is turning back on. It went off, the screen stayed black, then a few seconds later the screen turned on with an hourglass spinning for about five seconds, then the light turns off and everything goes black again for a few seconds, then the LED light comes on again and the cycle is repeated. It did this five times before I had to put it away as we drove home. When I got home, it had finally booted the whole way, but the battery was so low the radio was off, so I plugged it into the USB charger on my desktop computer.
When I came back later, the phone had stopped charging and was on a black screen with the LED light on, just like earlier. It went through this cycle a few times.
I pulled the battery and put it back in, same thing happened. Black screen, white screen with hourglass, black screen.
I plugged it back into the USB charger and as I type this, the little psycho has booted completely and it shows that it is charging.

How can I fix this so it doesn't keep happening? Thanks so much in advance.

Hi and Welcome to the Community!
Please try this sequence...note that, throughout the entire 4h15m process, your BB must remain connected to a known-good wall charger (not PC USB):
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.
It is also possible that your battery or BB has experienced a problem...to test, this sequence is needed:
Obtain a 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.
Good luck and let us know!

PPC MacMini shuts down immediately after boot, LED blinks

A client gave me his PowerPC MacMini which boots up but then shuts down after a few seconds. Unfortunately, there's not enough time to open the system preferences between booting and automatic shutdown.
I've tried to boot the computer from a system DVD and with "T" pressed for target mode, but it always boots up completely from the internal drive. Booting with "Shift" pressed boots in safe mode, but the machine still shuts down after a few seconds.
Interestingly, the power LED blinks about once per second. I wasn't able to find anything about this on the Net.

AndyO wrote:
If, on the other hand, the mini is starting up, and then failing, and the light isn't so much blinking as pulsing, then the system may be suffering protective shutdown as a result of overheating. That can be tested by seeing whether it runs longer after being left unplugged for several hours, thus being cold, than it does if it's been running (or attempted to be run) for some time, and is thus already warmed. In that event, the mini will need to be disassembled to some extent to try and identify whether the fan is running, the CPU heat-sink is firmly attached and the thermal pad which is squeezed between the underside of the logic board and the base of the system is replaced.
I have a Mac Mini Intel Core 2 Duo that is suffering almost the same symptoms (shut-down almost immediately after startup); however, it DOES appear to be for a variable length of time based upon how much time I let it sit and 'cool' down; therefore, I believe I'm experiencing an over-heating issue.
I've installed a matching 1GB pair of RAM about 1.5 months ago and all has been fine until now. The unexpected (which is now expected) shutdown after startup is occurring on both Mac OS X 10.5.2 and Windows Vista (on Boot Camp partition) ... of particular note ... the Windows side shuts down more quickly (likely due to it not having the same system monitoring/energy handling tools that would be available to the Mac OS X side ... so I would suspect it to over-heat sooner on the Windows side).
Successfully completed Hardware tests (simple & extended) reported memory and other system hardware was fine. 'Check/Verify Disk' on Mac/Windows side reported no issues with either partitions.
Attempts to reset the PRAM and SMC have not solved the problem.
There was one instance, after startup, that the fan ran at full speed continuously and noticed that the power light was not on at all ... at the time, I was on the Mac startup disk and it stayed up and running for about 20 minutes or more until I decided to shutdown and test the Windows side. Upon restart, the fan did not run continuously, and the Windows side shut-down shortly after start up.
Overall, I'm fairly convinced it is an over-heating problem. If anyone has any ideas or reference material to confirm or how-to-do "the CPU heat-sink is firmly attached and the thermal pad which is squeezed between the underside of the logic board and the base of the system is replaced" that would be greatly appreciated.
I am not ruling out sending the machine into the retailer for servicing/diagnostics; however, if there's a relative quick fix so that I don't have to identify and remove confidential/sensitive info first, that would be preferred.
Thanks.

HP Compaq 6715s won't boot on battery after BIOS update

Hello!
I updated the bios of my HP Compaq 6715s with the latest version F.0E I downloaded from HP support site.
Everything went fine, but now it won't boot on battery alone anymore. It just flashes amber light on power indicator and shuts down. If the charger is connected and later disconnected when it starts loading Windows, everything is fine.
Please help, what should I do?

Hi:
You can try performing a hard reset of the notebook in hopes that it will solve the problem.
Here is the link to the instructions for this procedure.
http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?lang=en&cc=us&objectID=c01684768&prodT...
If that doesn't work, I'm afraid something went kerflooey with your BIOS udpate.

HP Compaq dc7700 won't boot up. Beeps continuously and is stuck at the Windows loading screen.

My computer is a HP Compaq dc7700 Convertible Minitower desktop computer. The operating system is a Windows 7 32-bit.
When I try to boot up my desktop it just has the continuous beeping noise, there's no real pattern or red light. About 5 days ago I got a blue screen, but ignored it since when I rebooted it the pc worked fine. The only big change I've amde recently is installing World of Warcraft on the computer, other than that I don't remember making any big changes to the computer at all.

Compaq Presario won't boot up

I took out the new hard drive from my daughters PC to try in one of our other models Compaq Presario's but it didn't fit so reinstalled it in my daughters PC. When I switched on it gave a message - "A problem has been detected and Windows has been shut down to prevent damage to your computer. If this is the first time you've seen this stop error screen, restart your computer. If this screen appears again, follow these steps:"
It then gives instructions to check the hard drive and run Chkdsk /F but I can't boot up so can't do that.
I can't imagine what is wrong as I only removed the drive and then replaced it. I didn't drop or bang it.
Please help.

Norman Silva.

Compaq nx7400 won't boot

I have a Compaq nx7400 EY305ET notebook with WIn XP Pro and a recovery partition. Last time I rebooted it wouldn't. It reboots after 5 seconds in an endless loop and when I press F11 (Start recovery) it shows the bar at the bottom initializing the recovery and the logo with an XP-similar animated "loading" bar. 2 seconds later I get a blue screen:
"STOP: c000021a {Fatal System Error} The Windows Logon Process System process terminated unexpectedly with a status of 0x00000080 (0x00000000 0x00000000). The system has been shut down"
And this happens EVERY time. I've tried the WIn+B+power to restore the BIOSg the and I've downloaded the "HP UEFI BIOS Update SoftPAQ" and installed it on an empty, FAT32 formatted USB drive as HP suggest on their support website, but with no different result what so ever.
I even renamed the USB drive "HP_TOOLS" and tried again and then I renamed the installed folder containing the update to "HP_TOOLS", just in case, but nothing works. The screen remains black and empty.
And this is as far as I get. Suggestions anyone...?
I can also be reached at egw[at]live.se
I REALLY need to get this running. I have 2 days of important work I need to access. (And yes, I forgot to backup the last 2 days. My mistake)

Hi:
See if making this free bootable rescue CD will allow you to explore the hard drive and copy any files you need to a portable hard drive.
Download an instructions below. Use the graphic interface to explore the hard drive.
http://support.kaspersky.com/viruses/rescuedisk
Once you get the files off, order a set of recovery disks from HP by calling the number listed for business PC's/notebooks at the link below (0771-30 30 00)

You may also want to run the hard drive diagnostics test in the BIOS and see what it reports.

RAM upgrade, now MacBook won't boot

I bought 2 1 gig RAM sticks from Fry's and installed them in my MacBook and it won't boot. The LED on the front is flashing once per second, which according to the Support website means that it's not recognizing the RAM. So, I put the original 2 X 256 megs of RAM back into the MacBook and it still won't boot, LED is flashing. What the ****? I've tried inserting the RAM several times, I've firmly inserted it, it feels like it's seated properly, and I inserted it the correct way according to the little diagram in the battery bay. Don't know what else to try......

They go in quite hard. Watch this video and try installing again.

Won't Boot -- Blinking PowerLED of Death

Hi,
So I was upgrading the RAM on my Mac Pro and now the computer won't boot. It turns on and all I get is the blinking power LED. It's blinking once per second. I know that typically this means that the RAM isn't seated correctly. So I have reseated the RAM at least 10 times now. I have also tried taking out the new ram, and using the standard RAM that came with the computer, still not booting. I've tried swapping the riser cards. I've tried booting with just one riser card and alternating the slots and which card; still no boot. I have checked the seating on the harddrives, and the video card and anything else I can see. Still not booting. I've tried booting with a single ram stick in every slot, and even tried the same thing with all four sticks of ram; still nothing. I have also tried pressing the SMC RST button, no help.
*NOTE 1: When I turn on the computer, all four red LEDs on the riser card(s) light up for a second and then turn off.
*NOTE 2: When the power is on and I press the DIAG LED button, I get this only: TRICKLE - Orange, PWR ON- Green.
I guess my question is: where's the problem? Is there any way I can definitively tell if it's the riser card(s)? Is there a way I can just check the ram itself? How can I check to make sure it's not the logic board? Any help in what I should check would be greatly appreciated.

This problem also happened to me. Last week, I awoke to the blinking power light... Tried rebooting and no luck. Several times.
I read this thread and thought I would try swapping the memory around.
It worked! My MacPro is back to life - I was upset because it meant a trip to the Apple support center... Even though I live in Mexico City and there are the Authorized Apple Service Centers I'm glad I tried this before packing it up for observation. I can only conclude that this may happen again so for now let's hope all is well... and at best a temporary glitch. The odd part is that this happened two days after I moved my hardware to another location. I though perhaps a power surge occurred and tweaked the hardware.

Have a compaq cq61 319wm, blinking blue lights

i have a compaq cq61-319wm. when i press the power botton there is no boot or post. just blinking blue lights at the caps lock and the number lock. i have switched the ram around and even used other ram. any is appreciated.

I think you have to begin to think of this in terms of a hardware issue. If it reads CDs but not DVDs, then it is not a driver thing but a bad laser. There is a separate laser for CD and DVD functions and one can easily go bad, requiring replacement of the drive.

Laptop Won't Boot. Caps Lock Button Light Blinking

I just bought a HP Pavilion DM4-2015dx laptop a few days ago. Turning it on this morning, it won't boot and the Caps Lock light is blinking. I have searched the HP site and Google for a solution to the problem and have found nothing to tell me what the blinking light means or why it won't boot up. Does anyone have an idea of what the blinking light on the Caps Button means?

My laptop HP pavilion Dv6 - 7132TX had a problem of blank screen and caps lock key blinking. I bought the laptop on 28th Apr 2012 and just before completing a year, I was facing a problem of computer inadvertently not booting. It used to show black screen with wifi LED red, power button LED glowing, and caps lock key LED blinking. http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&docname=c01443366 On going to the above link, I tried to notice the number of blinks of caps lock key LED.Found that the blink count was an endless loop of 2 LED blinks. On checking in the above link, found that 2 blinks meant the problem was BIOS corruption failure. LEDs blink 2 times BIOSBIOS corruption failure(as found in the table in the above link) So I went on and found another link to find the BIOS upgrade on the same page , where it read, Step 3: Find and download BIOS updates Then followed to the link: http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?swlinkmsg=100&cc=us&dlc=en&docname=c00042629&lc=en&product=4057208 to download the driver. Downloaded the BIOS latest driver and installed it. It gave the same problem while restarting the laptop which was required to complete the bios installation. Link for the BIOS installation: http://ftp.hp.com/pub/softpaq/sp54501-55000/sp54629.exe However after several force shutdowns and reboots (since in my laptop the blank screen during bootup was inadvertent and random..) the installation could proceed and complete. After that voila.. Problem gone Hopefully it stays that way. Now next task on my mind is to fix the sleeping problem of my PC and the noise problem of the speakers. 1.Laptop does not sleep and goes into freeze mode with LEDS glowing and screen black.2.While the laptop speakers are on, they constantly make some background noise as if the speakers have a loose connection. However I got a clue that the problem is not with the connections but with the frequencies mismatch. Inherent problem of laptop architecture I suppose. However still wish to hear sounds clearly on my laptop. Had a good experience with HP with my earlier laptop from HP. However now things are changing I guess. Feel good that I could at least troubleshoot and save money. [Even gas is Rs. 84 per litre.] and more importantly time since I was working when I saw this problem and did not want to keep laptop powered on All the time just to avoid restart .

LED blink, no boot

Computer is not booting. Sometimes I get a 2 blink sequence from Caps Lock and Num Lock LED's. Most of the time however, all I get is a continuously blinking Caps Lock LED, then the keyboard dims (flashing LED continues) then about 15-20 secs from start the fan starts. No boot, no display on screen.
Holding down power button doesn't stop it, the only way is to remove battery and disconnect power.
I have tried:
Hard reset.
Clean the fan, and vents.
Remove, clean and reseat memory.
Booting with memory in second slot.
Remove and reinstall hard drive!
Connecting outside monitor.
Nothing has helped.
Any other suggestions/ ideas about possible cause? What does the 2-blink sequence mean on this laptop?
TIA

Hi rafael, and a Warm Welcome to the Power Mac G5 Forum!
Whilst not wishing to give you false hope, a similar 'one flash' problem was fixed by experimenting with the RAM here
http://discussions.apple.com/message.jspa?messageID=3338765#3338765
So, you could try taking out any added RAM and see if it will boot with just the original "Apple" RAM. If it does, you could try replacing the added RAM, in pairs, and try it.
If it won't boot with just the original RAM, you could try removing and then replacing it - sometimes it's just a bad contact in the slot. This might be the problem with the added RAM too, rather than the RAM being faulty. The RAM DIY instructions are here
http://www.info.apple.com/usen/cip/pdf/g5/memory_c.pdf
Note especially the static precautions.
Once you get it to boot ok, you could run the Apple Hardware Test
http://www.thexlab.com/faqs/aht.html
esp. noting the links to Memtest/Rember further down the page.
As it had a forced shutdown, you could run Disk Utility (the one on the 10.4.8 drive) and Repair Permissions and Verify Disk.
Good Luck.

Laptop won't boot caps light and Num light blink

My Ts2-1375dx won't boot after I have shut it off and turned it back on. I get the cap & num lock lights blinking once. I remove the powercord, battery and all attached peripherals, hold the on button for 30 seconds reconnect the power and try booting again. Although this works (maybe after 1-3 tries) I don't believe that this is the way you should have to boot the computer. I also see lots of the same problem with the solution being the method I use. WHY IS THERE NO PERMANT FIX?!?!
This question was solved.

umm have you connected the power cable for CPU? sounds rare question for me, sorry .. All I know is CPU is seated into socket where get power. Power ATX 24 pin power connector to mainboard is properly connected. or are you talking about ATX 8 Pin power connector JPWR2? is it that?
. Also I tried and clear CMOS just using 1 stick RAM the slot close to CPU. nothing got it. Debug LED FF . no signs of CPU no debug Led Must see CPU LEDs On . as for me trouble is on CPU or motherboard. when you install CPU did you push hard down and closing lever? I installed CPU like manual say completely embedded into socket and closing lever I didn't pushed . Have To push hard it? what you think about? I 'll Try tomorrow removing motherboard and reinstall Properly as I did and everything back again.
