Note on archived topics.
I have a Compaq Presario CQ61-310SV notebook that does not want to start — the screen does not turn on and always remains blank. At startup, when I press power button:
- Lit only leds for Power, WiFi (orange color) and Touchpad;
- The fan turns on, but the screen remains blank;
- Caps Lock and Num Lock keys blink 2 times in a sequence;
According to these data, I found that there was an error, indicating to failure of the BIOS. But, despite the fact that on the forum I found many of similar cases, no advice did not help me solve this error. So I decided to ask you for help, describing in detail what I tried hoping that you will point to my mistakes and help me to solve the problem.
- First of all, I tried to perform a hard reset by:
- Disconnecting the AC adapter, battery and all external peripheral devices;
- Pressing and holding down the power button for about 1 minute;
- Plugging the AC adapter back into the notebook;
- Trying to turn on the notebook;
- Next, I tried to recovering the BIOS using key press combination «Win+B» hoping that my notebook has the emergency BIOS recovery feature enabled. But the notebook silently restarts automatically after few seconds after I released the power button. How I tried to do it?
- I turned off notebook and I unplugged AC adapter;
- I disconnected the battery and all external peripheral devices;
- I plugged AC adapter back into the notebook;
- Holding «Win+B» I pressed power button and I released it after few seconds;
- Afterwards I tried to recover the BIOS using an external storage device. For this:
- Using another computer I downloaded BIOS update from HP servers;
- I extracted files from archive and I copied «363FF13.fd» file to USB key;
- I renamed file «363FF13.fd» to «363F.bin»;
- Holding «Win+B» I pressed power button and I released it when I heard the first beep;
- I counted the number of beeps that are played in the following order: ...-.-.-.-.-.-.- where „.” is a beep and „-” is the pause;
- After last pause nothing is happening — no beeps or restarts (at least within ~10 minutes). Only Caps Lock and Num Lock keys blink as mentioned above.
I want note that I have tried all available BIOS versions (F03, F12, F13, F15) — and always got one and the same result. By the way, for example if the USB key does not contain the file «363F.bin» after releasing power button, notebook play a single beep and restarts automatically. If I put an empty file «363F.bin» on USB key — notebook play only 3 beeps and dont’t restarts.
I do not know what happened with this laptop — it worked fine until one day when trying to turn it on, came the "big dark". Before that, did not make any updates or upgrades.
I really hope that you can help me.
I am very grateful for your reply, however on the specified page I have not found a solution for my problem — the notebook already been cleaned of dust, and, also according to number of blinks specified in chart, the notebook have a "BIOS corruption failure".
Considering that the problem is not solved, what else should I try/read?
Thanks again. But, as I said in my first post, recovering the BIOS using key press combination «Win+B» not works for me.
This is why I tried to recover BIOS using the second method. So, when HP BIOS Update UEFI finished installation, the USB key was renamed to HP_TOOLS and here were created the following files (just in case, I pasted the entire output of "tree" command):
C:\Windows> tree H: /F /A
Folder PATH listing for volume HP_TOOLS
Volume serial number is 00000002 941B:AF53
Trying to start the notebook using «Win+B» — has not given any results — notebook plays a single beep and restarts automatically. After that, I guess, that the folders "Current", "New" and "Previous" should contain the BIOS files. And I copied the «363F.bin» in the each folder and trying to start notebook — but again without any success.
Maybe, I need other/more files?
Or, maybe I need to use another filename?
The same thing happened to my Compaq Presario CQ-61-335ev. I myself tried everything that I could think of to no avail. I also got the problem out of the blue. It was working fine before the screen went black.
I didn't have the HP_TOOLS partition on my hard drive to do the Win+B recovery and had to use the USB. I also copied HP_TOOLS from a different computer and replaced the bios files and added it to my laptop hard drive (via a different computer) to try running the recovery through the hard drive. No luck.
What I am surprised is the fact that almost everyone on the internet and forums is clueless as I am.
(By the way, do you have your HP_TOOLS partition intact? Can you upload a copy of it somewhere online? The issue with me might be the files in the HP_TOOLS partition I copied)
The issue you are describing with your Compaq Presario CQ61-310SV appears to be a physical issue and I think it would be best if you contacted HP technical support for repair options.
