Presario CQ 71 doesnot start

Hello

I have a presario CQ71-200BS model.

It will not start over.

If I release the battery and the plugin burns the power LED of the power supply, but it does not start.

IF I connect the battery and then the plugin the power the power LED will not burn.

Is that the power supply is faulty?

Please help me. THX

Peter

You will need to unplug the BIOS (RTC) battery to clear the CMOS settings. Here is a link to the Guide to maintenance and Service for your series of specifications model. See page 59 of the manual. It is actually quite easy. All you have to do is disconnect the battery and leave it like that for half an hour or so. While the battery has been removed and the external power adapter disconnected, press the power button and hold for 15 seconds.

Who needs to actually reset your laptop.

Is your laptop still within its warranty period?

Best regards

ERICO

  • Presario CQ40 does not start in Windows

    Hello

    My cousin has a Compaq Presario CQ40 (w / Windows 7 Ultimate 32-bit), who has a serious problem at startup, it shows a blank screen with only blinking cursor in the top left of the display after the Compaq logo.

    I tried to load the default in the BIOS Setup, but nothing happened. I also tried to insert my DVD of Windows 7 to check any problem at the start, but it won't let me boot from it, just another black screen with blinking cursor. The only successful "start" method is to use a Ubuntu via flash (Live USB) drive.

    Help, please.

    P.S. It use Windows 7 for a clean install, without any backup OS preinstalled this laptop /recovery.

    Hi erico & ericpol911 and thanks for your reply.

    In fact I solved. After you restart the live USB laptop I can boot from the Windows DVD (previously the I can't). So I choose 'repair' the DVD and type "bootrec /fixboot" and then restart, and it works.

    When you say you tried changing IDE emulation you mean that you changed or have you been unable to change it to IDE?

    Please rephrase the statement for me: "before I test the hard disk to connect to the other laptop via USB to sata interface successfully formatted using ntfs file system."  I really don't understand what you mean.

    Windows XP Home edition doesn't have a native SATA drivers for installation. SATA drivers must be provided during installation.

    Perhaps the creation of a Windows 7 professional install thumbdrive since an iso would be a viable option if you know how it is made. If you have a disk or an iso file, then the Windows 7 USB DVD download tool would be perfect. You will need to make an ISO of your installation of Windows 7 Professional DVD file, you can use the tool.

    What was your original operating system and you have the defined recovery disk?

  • 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,

  • HE commands to work - Compaq Presario SR5000 does not start

    I have a Compaq Presario SR5000 running Windows Vista Edition family basic and once we got in, I first cleaned the internals to the air compressed, then tried to start, and it failed, so recommended BIOS I run the Startup Repair tool and so I did, and the startup repair couldn't fix the computer "automatically".

    Now, I run the system restore and I tried to restore the computer to its last Windows Update, and I got the error code 0 x 80070002, meaning that the system cannot find the specified file.

    Specifications for the Compaq Presario SR5000 I have:

    AMD Sempron LE-1250 to 2.20 GHz

    2 GB PC2-6400 DDR2 SDRAM Samsung

    Windows Vista Home Basic

    HP M2N86 - THE mother

    Power supply PS-5251-08 LiteON 250W

    Well, if this is the case, then I think you may try to access BIOS, if that does not work then go ahead with the HARD drive option. I had this problem before and I wiped the hard and it worked eventually. If this does not work, I will try and find a different solution.

  • Presario V6301AU does not start

    I would be very grateful if someone can help me with a problem I have with my Compaq Presario V6301AU laptop, it's barely a year old and very well cared. I went to start one morning and then the blue lights all lights near the controls volume and the seizure of power, and DVD player makes a noise at startup, is that it will, the screen stays off and after awhile it stops and re-housing starts... it repeats again and again.

    Please help as I need this laptop to do my job and I have no idea what's wrong... worse yet, I already bought new ram and a new hard drive any of these things solved the problem. He never came in contact with water or moisture potential, has not been abandoned and never used on a solid flat table, I also it don't move during operation in.

    It then, I wish I could help you more.  Let's see if someone has some ideas.  I cross my fingers.

    Good luck.

  • 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.

  • 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.

    +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

    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.

  • Compaq Presario F768WM does not start

    I have a presario F768 that no longer starts.  Blue power light is stable, power cord.  When I press the power button, the blue power lights the button lights up with the power led and hard drive indicator.  After a second, all the lights go out.  power indicator at the front goes out for a second, then back.

    I tried the hard reset, remove the memory and disk hard and always the same symptoms.

    It started after an update Vista hung and computer had to be turned off manually.

    Looks like your motherboard has gone bad, I know that cell phones series F700 comes with NVIDIA GeForce Go graphics. What plauge of HP and Compaq laptops. what you call sounds just like what everyone has experienced this same problem.

  • Compaq Presario CQ61-406SA not start.

    Hello

    Was given this computer by a friend to try to find out what is wrong with it. It does not start and the Caps Lock/Num Lock LEDS give a flash code that seems to indicate a CPU problem. Have reinstalled the RAM, wireless card and the hdd - even. Have tried to start without anything plugged - even. Tried the hard reset - same. And we tried the reset of the BIOS (windows + B) - still the same.

    As it is out of warranty (expired on August 27, 2011) I was wondering what could be done. What would be the best package of care to buy... If the owner is willing, of course.

    Thank you

    John

    Hello

    Have been in contact with support by phone earlier today and the price quoted for repair is excessive (€253 / $331) in the age of the computer, so the owner will get a new one instead. Thanks for the reply anyway

  • Compaq Presario CQ61-420US no start/black screen

    Hi all.

    I have a compaq presario CQ61-420US having similar problems below, except I have a black screen, fan flashing lights turns is the same (num lock and cap lock) but they Flash continuously every second or 2.  I tried the hard reset with the fix of ram, connect an external monitor, change the battery and the power adapter, nothing helps. I also used the air compressed on the vents, just in case was riddled with dust because it overheats and can cause problems, but nothing.

    Any other suggestions?

    An option I can think of is to buy a new motherboard, but I'm going to try something else before that.

    AlexisGonzalezC,

    You can try the above solution the other person sugguested.

    Sorry, but it is very difficult to help without a touch your computer and troubleshoot it if there is a hardware problem.

    I predict that GPU your computer has a pseudo brazing or cold joint problem.

    Good luck.
