• HP presario CQ61 won't start, blackscreen, no noise, capslock and numlock blinks 2 times.

  Hi all!

  I have a presario CQ61, which does not have anyting when I turned it on. The screen remains black, the fans start to run and I search for CD-Rom. Uppercase + numlock sparkle for 2 times in a row and then a short break and then they start again.

  I tried a hard reset, removed the CMOS battery, reinstalled the memory and the hard drive is not attached at this time.

  I hope someone has an idea of what is wrong with the laptop.

  Thanks in advance,

• Compaq Presario S4500UK won't start after disconnecting from the wall outlet. What is a CMOS battery problem?

  Reconstruction of recent software with HARD drive internal extra (March 2011) under Windows XP/Linux dual-boot installation worked fine.  CD/DVD RW drive, started giving errors so replaced cyclic redundancy check drive a week ago.  All still OK.  Change of electricity supplied and increases energy use conciousness off the machine to the outlet of the overnight after normal shut down.  Machine will not re-start not in the morning.  Not load BIOS; all lights came briefly and then die after 3-4 seconds with power still led on.  You can get a similar effect by plugging the keyboard into the PS2 Mouse Jack I did once!

  After 20 minutes or so try all kinds of things managed to boot from the CD of Linux.  Shut down/restarted and everything is fine so I don't switch off at the wall.  Also seems to be OK after brief power off for 5-10 seconds but the problem persists with any long disconnection.  It seems that after 10 to 15 minutes from power-on and 2-3 attempts to restart, BIOS comes up and all is well, but he stopped in the middle of a start of Windows or Linux on a couple of occasions.

  Am I right in thinking the problem might be the result of a dead CMOS battery?  The reason that I ask is that the clock seems to keep time OK and there is no apparent problem with the BIOS once it loads.

  Any help/advice would be much appreciated.  New config info below.

  Dual boot Windows XP Pro SP3 of Compaq Presario Bios v3.03 S4500UK / Linux Ubuntu 10.04 Lucid (2.6.32 - 33)

  CD/DVD-ROM (original JLMS XJ-HD166S)

  Recently installed HL-DT-ST DVD - RAM GH22NP21 replacement NEC ND - 1100

  I don't have all the answers so I went forward with replacing the CMOS battery, but that did not help.  The problem is also obvious if I turn it off and leave it for an hour or more before trying to restart even if I do not unplug the wall plug.  It seems to take about 15-20 will start again before it fires.  I would be really grateful for any clues as to what is wrong.

  OK, guys.  I finally solved the problem.

  After you have calculated the power needed for the config curent, I discovered that, using various ways to estimate, he walked between 321W - 383W.  It was pretty weird that the only thing I added was a HARD drive and a memory stick and the wisdom of the other guys on this forum, it's that there is a lot of capacity within the factory installed power of 250W.  Yes and here's the rub: the modern replacement devices usually have upgraded capabilities and use more power.  And so when I replaced the drive CD/DVD RW added a few watts, as the sectoral approach of the floppy drive.  It appears also that the optical USB mouse needs more juice than the good old PS2.

  I just installed a new 450W PSU Powercool and Bingo!  The processor is faster, too.

  Hope that my pain and trauma saves someone else having to suffer the same.

• Desktop Compaq Presario has beep and won't start

• Desktop won't start no-of faulty power or motherboard?

  Compaq Presario SR5000/Windows 7 Ultimate 32 bit

  I had this problem for a few months - the Office doesn't turn back on when I unplug and plug it back and the green light of the power cord blinks. Based on the troubleshooting guide from HP for this flashing light, I was able to isolate the problem to the connector 24 pin main that feeds the motherboard. Whenever I got in this regard, the light was stable. Thus, the last two times I've been able to bring the office back to life by unplugging / plugging the 24 pin connector.

  This time, of the power supply does blink everything as long as the motherboard is powered but puts constant green when I get this connector.

  I tried the hairdryer mentioned here http://h30434.www3.hp.com/t5/Desktop-Hardware/Desktop-won-t-start-blinking-green-light/td-p/4467 but stuff that no longer works.

  As the POWER light turns off when I have the motherboard power and turns on when I win, I don't know which replace - block power SUPPLY or the motherboard but obviously one of them is the question.

  Power supply model #: Bestec ATX 250 12Z

  Thank you!

  Power supply failures are much more common than the failings of the motherboard... and less expensive to replace. I have a machine now sometimes, which flashes and takes a few coachig at startup if unplugged for awhile and anticipates a new power supply in the near future.

  If you check the specifications and dimensions, you can buy a replacement WHAT PSU to many points of sale, or online at places like Newegg.com or Tigerdirect.com pretty cheap.

  You could also first remove the power supply and take it to a place that makes the PC repairs and ask them to test it. I bought a tester of POWER a few years ago that saved many hours of troubleshooting.

• Presario SR5507F does not start for Vista after "Windows Update"

  One of my friends has a Compaq Presario SR5507F. She is old and doesn't know much about computers. She told me she had a message that an update of Windows was necessary, so she hit 'continue' and walked away. When she came back, the computer was restarted on a screen, she had never seen before: a black screen, with the 'C' and "Compaq" logo in red in the Center, with " and " on the lower left and " and v5.27 ' on the bottom right side.

  I checked to make sure that the keyboard was solidly connected - the NumLock lights etc flash momentarily when the computer starts.

  We have tried pressing ESC, F10 and F11, in various methods: turn on the computer, and then hit the button, turning on the computer using the button is pressed, turn on the computer and repeatedly hit the key, etc.. All had the same result - the screen with the logo of Compaq, and nothing else happens.

  I know that some on computers, but that me stem.

  Of course, she didn't know she should do a set of recovery discs, is not so... she.

  If anyone has any ideas, I'd be happy to hear.

  Hi biolabprof01,

  Sorry to hear about the sentence. There are a number of things to try. First, try the procedure described in this HP support document on Vista won't start do not.

  If you can, try to perform a System Restore or System Recovery.

  If you still cannot start and cannot access the System Recovery Wizard, you can order HP recovery disks (see the section on CD - ROM order page).

  I hope this helps. Let us know how it goes.

• Qosmio G20 - won't start, error ATA #1

  I have a G20-102. Today I opened my flash drive and files all showed them as shortcuts. I tried to connect to Firefox 4 and a warning from AVG threat came pointing to C:\windows\system32\mssrv32.exe (Tr/Crypt.xpack.Gen3) as a Protection of identity. I opted for the "Move to vault" option and asked to restart

  Now my pc won't start - I get the Qosmio screen, ATA error #1 (CD player has been removed) and then the screen "rolls" - looks like random pixels flashing on the screen. I'm trying to start safe mode, but F5, F8 or any Fkey is not doing

  To make things worse, the CD rom has been removed, faulty, so I can't boot from another device. I don't have a USb in the BIOS, only FDD option which I did not

  Help, please

  Hey,.

  To me, it looks like a serious hardware malfunction

  You could try to load the default settings in the BIOS. Enter in the BIOS, and then press the F9 key to load defaults. Then save & exit the BIOS and try to start again.

  The HARD drive is recognized correctly in the BIOS? If so I try a recovery disk Toshiba recovery installation and check if the problem is hardware or software partners.

• MacBook won't start - completely back screen

  2015 12 '' MacBook

  My MacBook won't start. I put on various points of sale and even changed on the brick of cable and power (I have an extra).

  Nothing happens when I press and hold the power button.

  Any suggestions before I take it to the Genius Bar?

  Here is some information that might be useful.

  After I press the button for a few seconds, the trackpad does not haptic feedback, confirming that this is the start.

  However, if I press the power button once again, I get haptic trackpad. It tells me that it is on, but I always get a black screen. And if I press the caps lock key, no green light appears.

• Satellite Pro 2100 won't start at all - LED flash

  My SP2100 began to have feeding problems and now won't start at all. The AC adapter green LED is lit, that are relevant lights on the body of the laptop (although the "battery charge" light always orange these days). When I try the switch on, startup begins (in fact succeeded on occasion until this morning), however the battery indicator and the adapter lights are flashing, and everything stops again.

  On the rare occasions when I'll be past this stage, lights blinking, and the system soon shuts down again with a screen message "low battery." Until this morning, he would sometimes settle, the computer remained on, and the lights showed a State of equilibrium as usual.

  Initially I thought that the problem was of course the battery or the AC adapter, but now I'm starting to think that it is with internal PSU of the laptop (although I suspect the battery is probably tour after all this part of loading and unloading).

  Any ideas?

  Hello

  I think you're right. Flashing LEDS are a sign that hardware is defective.
  I can't say what exactly is the problem, this should be verified by a technicain.
  On the other side I don't know if it's worth to repair such an old machine.

  Good bye

• 4600 won't start

  Hi, community,

  my pro sat suddenly won't start. only power led flashes. Got out of the car, a piece of metal appears to be noise. But - if the drive is broken - shoulnd't the laptop will start anyway? Thank you for your help in advance. Wolfgang

  Hi, Wolfgang

  Yes, the machine must be able to start up indicating at least the TOSHIBA logo without the optical drive and fixed.

  Some background info: flashing DC-IN means that you have a problem of power supply to your machine.

  Please delete what you can without using a screwdriver. PC card, battery and so on. If you have 2 mem cards remove one.
  When everything is there, try to restart the device. Keeps blinking? If you had 2 plates of mem, remove the still inside and install another one in another location. Try again. Always the same?
  So I guess that there is a physical problem with the machine.

  If the machine starts normally, try turning off and to reconnect one removed items at once turn on the machine after each reconnection.
  Test them one by one and see if you can find out if there is a specific that causes this problem.

  Good luck!

  Tom
