Presario cq71-320SA In-car load

I often use my laptop in the car in Park, before moving on to my next appointment.  After a while, the battery runs out.

Is there an easy and safe way I can keep the battery charged by plugging it into the 12v Jack in my car (a VW Tiguan 2012 that has several plugs 12v and USB cable connectors)?

If so, is there a particular product should I buy to connect safely and securely?

I guess (but I don't know) that it is not safe or suitable simply connect the laptop to the system of car battery using the USB connection on the car and laptop computer.

I would appreciate any advice from one who knows these things.

Thank you

Yes, the safe and easy way to do it is with an "inverter" that plugs into the socket of the cigarette lighter and allows you to connect the ordinary portable computer AC adapter. Truckers use so they are sold any type Roadhouse gas station or any electronics store.

Like this:

I would not get much smaller than this capacity... 300W should be plenty.

  • Compaq Presario CQ71-320SA: failure of the update of the BIOS via Support Assistant / should I update anyway?

    This morning I found that my laptop had not finished closing 8 hours ago. I stopped by pressing the button Off for 6 seconds and restarted. I then looked a likely cause and saw that a BIOS problem was probably the cause.

    I'm went to the site of HP support & with information about http://support.hp.com/gb-en/document/c00007682, I followed step 1 and I saw that my BIOS is F.11 21/08/2009.

    Support site told me that I need F.11Rev1/20/10/2014. I installed, rebooted and saw that he had failed.

    What's worse, is that the program Insyde update it says that the 2009 version is updated - see below.

    A kind person could tell me what I should then?

    More old Compaq Presario CQ71-320SA screwed up by free upgrade from Microsoft of Win7 for Win10

    Hello

    You can manually update the BIOS for your laptop by downloading from the link below:

    The current version available is F.23

    http://ftp.HP.com/pub/SoftPaq/sp51501-52000/sp51527.exe

    Once the download is complete, double-click the downloaded file and follow the instructions on the screen.

    You will notice may-continuous display blank for a few seconds, which is quite normal. Once the update is actually the device automatically restarts.

    Note to back up your data before performing the update. Also have your adapter connected to the laptop.

  • Compaq Presario CQ71-320SA: how to back up the registry

    I need to change my internet browser for Secunia PSI - it is to make changes to the registry. As I am a PC-numpty (a technical term) an expert on the PSI forum gave me a walkthrough.

    The first step is to back up my registry. I back up my laptop every month that you are prompted by the excellent Action Center of HP but can't find how to make a backup of the registry just. Here, a search found many threads, but none of them relate to my problem.

    Could someone help me please?

  • Compaq presario cq71, sudden death, does not start

    Compaq presario cq71-140ea. was fine yesterday but this morning it will not start. It turns on, displays of compaq on the screen and then does nothing. Have you tried pressing f10 to change the sequence of boot for the relocation, but it just says bios configure options at the bottom of the screen and will not actually in it. All keys have the same effect. Says on the bottom, what is it but isn't "doing". Does anyone have any ideas on how I can him get up and running?

    Ruling on a BIOS corrupted, removing the CMOS (exhibit) just battery resets the default settings for the BIOS, but you do not have to remove the laptop battery as well. Did you remove the two batteries?

    I still really want you to try to boot the machine with a stick of memory removed.

    Here's a good video youtube, that he mentions on the battery and electric shock _ you won't electrocute yourself, the voltage inside a laptop is very low and also the battery will be removed.

    http://www.YouTube.com/watch?v=dbvmRsSh210

    Remove the stick dessu first (you don't have to replace the cover on the penalty), insert the battery back in and start. If no luck, remove the lower Strip and try this one. If it does not always start upward, then I would say that the BIOS is damaged. If it starts, then you have a bad stick of RAM.

    The RAM sticks are matched, you can't make them in trust, me it's a very simple thing to do.

    http://h20574.www2.HP.com/default.htm?lang=en&cc=us&hpappid=psml

    Also here is a link to HP multimedia Services library and some screenshots as getting there.

    When you click the link you may have to sign in again, giving the two pages of time to load, especially the other, it takes about 30 seconds.

    In the video he says you only touch the memory stick to the edges, it is a good idea, but I've seen people deal with it very casually and it's always nice. However just follow the steps in the video.

    I mention this once again and that's to make sure that you're statically discharged before opening the laptop.

    After trying the solution of the RAM (Random Access Memory) and if it fails, you will need a 1 GB flash drive. If there is something on this subject, and then save the information we have will be formatted.

    Flash player is required to save your BIOS.

    I guess we'll use your computer for girls, so I need to know what operating system is on it.

  • Compaq presario notebook CQ71: mother of computer laptop compaq presario CQ71

    mother of laptop Compaq presario CQ71

    I have a question an abot in Selangor, this motherboard.

    the graphics chip is separate or integrated.

    My cq71 crashed and stopped working continuous overheating by weak graphics.

    so ive decided to spend the whole motherboard.

    but I need to know to or if I could spend graphics.

    I have already upgraded to the ram for the future graphics card integrated.

    also additional guides on how to pass map main would be apprteciated.

    No RAM, but you would like to install a better processor, too. Look at the manual for CPU options. They will be pretty inexpensive at this stage. You should also another radiator/heater unit to work with the different video chip. But it adapts to your chassis. The only way to look at this case if you do your own work. Otherwise, the cost will approach the price of a new laptop computer. Even do your own work that you will probably have to spend more than $150.

  • Compaq Presario CQ71 Ser: CNF01002QT model CQ71-4142F - Dead - no power supply - does not start - no led

    Hello *. *

    First time here...

    Compaq Presario Notebook Win7 32-bit - 4 GB DDR2, aged about 3 years?

    A customer brought this with virus / malware issues - arranged.

    On start-up, the bios made regular account that the HP OEM battery must renew. Not difficult technical question here.

    Powered on the laptop without the battery and the pc has stopped completely after a few seconds.  No beeps, no LED. Suspecting power, the original showed 19.* * volts. Ok.

    Bidirectional p - s for another check the jack plug connection. No change, tried jumping jack plug connection.

    Out two-way RAM for good, no change.
    Two-way 2032 battery of the bios for good, not change.
    Removed HARD drive, no change.

    Non-powered from DC or battery, depressed and button who was held for at least a minute, without change.

    The bios battery removed for 30 minutes, without change.

    Fan do not get stuck.

    No attached devices.

    Remarkable:

    Without battery : white DC power LED stays on for about 5 seconds. And then off.

    Old battery included: white DC power LED does not illuminate.

    I did not remove the optical drive, because I think it's ok. Works fine (or used to).

    I am familiar with this series of Presario laptops / laptops and while I have tried everything I know, I was wondering if, before I have conviction as having a short-circuit motherboard / failure, is there anything else I can try with this model of HP laptop before I am progressing with the send for repair of component.

    Thanks in advance

  • Presario CQ56 - 154CA does not load BIOS

    Hello, I have a compaq presario CQ56 - 154 mobile CA. I deleted the hard drive using DriveCleanser to True Image Home 2011 and then tried to load the recovery with F11 (or F10 or whatever it is) Manager, but now all I get is a red screen with the big Q logo with "Press ESC for boot menu" on the bottom left and it just hangs there. I wipe the Win7 and system partitions, but not the recovery partition. I did a backup of these 3 partitions on my external hard drive, but the laptop does not start from a flash drive bootable, that I did in True Image, nor any of my startup CD and I set the bios to boot from flash first, then the DVD, then drive before wiping.

    I don't have the DVD with Recovery Manager recovery in Win7, but I wouldn't need them not from the recovery partition is still there.

    I read that some Compaq portable computers use a utility on the hard drive to load the bios, boot etc menu, so if this is the case with mine, then it has been completely removed. If this is the case, is there a way I can get it on the drive?

    If this isn't the case, I could try to remove the drive and put it in an envelope outside and connect to my office. It is possible that I can use the flash drive to use True Image to restore wiped two partitions. Also, I read that in this case, remove the disc and then turn on the laptop may allow the bios load, but I'd really prefer not to take the drive if I have to.

    I have faith in your ability to help me with this, thanks!

    Get off drugs or get back at them

    I seem to have solved the problem! As soon as I was able to restore the partition of 'System', which is the partition active, the bios loaded no problem. After the release of the bios, the Recovery Manager has finally started automatically and I was able to restore the laptop to its "out-of-box" State

    What I did buy a 2 1/2 inch, SATA HARD drive, USB adapter I used to connect the player to the laptop on my desk. I used my flash boot disk image first restore the MBR on the drive by using the backup that I did. That did not work. Then I restored the system partition, crossed my fingers and pulled to the top of the laptop again and finally the Recovery Manager came. It was the most beautiful thing I've seen in days.

    A little advice. If you want to clear Win7 out of your Compaq, say you want to sell or something, and you want to use a method of multiple passes, clean partition "Win7". Don't wipe the 'HP tools', the 'system', or the 'Recovery' partitions (is there such partitions). If none of this has meaning for you, find a friend or a tech store, he does not sense of. I consider myself lucky.

    Thanks Charles for your answers, I appreciate them!

    CQ62-a20EC works correctly with both above mentioned functional power supplies.

    There is another problem that appeared in fact after the update of the BIOS (F.8-> F2. (B).

    (Press F2 during POST) diagnostic-> battery test system:

    -F.8 BIOS with defective power supply = > has failed with the message "no adapter not connected" - this seems reasonable

    -BIOS f.2bs with defective power supply = > failure with "primary - replace (30)", failure id: 0GFM7R - 52T 693 - 9XL03G - C0E903 - sounds strange and I do not expect such different error after BIOS update

  • Compaq Presario CQ71 - error 1002 when using recovery (windows Vista)

    Hi guys,.

    I just encountered error 1002 while using the recovery... Recovery successfully crossed reformattng my drive, but crashed before reinstaling the original content. It's okay if I'm trying to hard drive or dvd rom recovery, all this translates into error 1002. I did some research and it seems that it is a very common error in hp without adequate solution products. I think I'm out of luck because my warranty expired years ago... How can I solve this problem? For me, it seems that recovery content originally placed on my hard drive (and later burned on the DVD by me) had been damaged. I see 2 possible solutions here:

    -to order an another recovery of the drives together (although I saw a few reviews it did not)

    -buy the new "Windows" and install a new fresh install (I will be able to perform the new installation at all?)

    I'd really appreciate pointers as I really don't want to lose my money for a solution that would work!
