• In version 13.0 is selected the option "when Firefox starts to show my windows and tabs from last time", but I always get default page of Firefox.

  Even thought is selected the option ' when Firefox starts to show my windows and tabs from last time "I always have the default page of Firefox.

  Hi Goldie_,

  I guess you don't watch this page when you closed Firefox last time. Also that you are not in private, correct navigation mode? Looks like it is maybe a problem with Firefox being able to save your file pref.js. You should try the steps listed in the preferences section that won't save trouble. Try and let me know how it goes.

  Hope this helps!

• 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.

• 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 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

• my computer laptop presario won't start, the screen is black and a shrill alarm sounds when I turn it on

  My laptop is a Presario F700 l PC, Vista operating system.

  We live in Italy and service broadband and wireless local apartment acquired last week.  We also bought and installed a Canon printer.  This computer was used in Italy before.  It was purchased in 2008 and also used in Manila and Yokohama.  I just had 'set to top' and checked before leaving the United States in September.

  I do not have the complete operating manual and I know what a yellow light on the front does mean something but I have no idea what.  The computer has been acting 'strange' for about a week in which he wont 'stay' at the top of a list of e-mail, the Office does not 'click', and it activates a different screen of the selected.

  IM technologically dim and this computer is my only link with "House" and my source of planning in Italy-travel. "  Im trying not to panic.  Thanks for your suggestions.

  Thank you very much for this - it's reassuring to know the resource and quick response is there.  I had already tried a solution I found online fixed 1/2 of my questions, but feel sure that these steps will finish my dose.  Thank you very much.

• Compaq Presario CQ61-313US: replacement of the CPU Compaq Presario CQ61-313US

  I have a laptop Compaq Presario CQ61-313US VM367UA #ABA that I am refurbishing and it must have replaced CPU. It comes stock with a CPU AMD Anthlon II M300 and I wonder if I can replace it with a CPU AMD Anthlon II M340 since they are the two socket S1, 35W TDP and they were released at the same time, so I think that the firmware should support two processors. I build that several desktop computers and laptops repaired but I traded not portable CPU oout before any info would be appreciated.

  I would say that you were right, because I have worked with several CQ61 CQ61 - 415st comes with this CPU.

• My Presario CQ61 NoteBook does not start. It shows a white screen.

  Hi, I'm back. This time, my laptop displays a white screen when I turn on. In addition, Caplock and Numlock indicators blink for 3 times and then the system powers off by itself and turn on again with a regular flashing, almost to infinity. I need a help. What could be the cause and what is the solution? Thank you.

  Hello

  If you have several modules of memory installed, try the following.

  In regards to the link below, delete one of your modules of memory and then see if the laptop will start.  If it doesn't, try the same module, but in another location.  If it is still won't start, try the other memory module in both slots, to see if any combination will allow the laptop to start.

  The procedure for withdrawal of these modules is detailed from Page 56 of your & Maintenance Guide.

  Kind regards

• Compaq Presario CQ61-416SA: upgrade the Compaq CQ61 wireless card

  I have a Compaq Presario CQ61-416SA, running 64-bit Windows 7 application. The current wireless card only works on the 2.4 Ghz band and I want to upgrade to a dual band to get the best speed etc. to 5 GHz. I have an Intel Centrino N6230 of replacement card, but the phone will not accept anything other than the default map. At the start, it stops with an error message saying that it will not continue unless the "unauthorized device" is deleted. If I re - install the original wireless card, it starts and works very well, but this is not the point, I would like to update.

  I guess that the default is to lock the part of the BIOS of the laptop to prevent alteration unauthorized with laptop computers under warranty, but mine is well outside the guarantee.

  I know that the card works because I installed it in my laptop previous and I have been in electronics for 30 years and spent about 5 years of this repair of computers laptops, desktops, servers, etc so I'm sure that I am able to connect a card and the driver installation!

  There does anyone know a way around the block? I won't to be able to upgrade the laptop without it.

  Anyone?

  Do not completely blame HP, but it was little 1984 involving your federal Government. HP and Lenovo read a few Federal Communications Comm regs on the recording of radio portable wireless (including the computer wifi cards) to require that alternative cards are blocked. Other laptop makers has not agreed and now the 'white list' is history, but there is no effort to go back and make new BIOS for older models.

  HP wireless card versions have specific identification in the firmware looking for the HP whitelist before clearing the map to use if you use the version of HP. I looked pretty hard for a version of HP of the card and the one I linked is everything I could find. Google around and you can do better.
