Question about Compaq Computers & Internet

1 Answer

Compac laptop won't boot up, just shuts down at each attempt.

I have a Compaq laptop presario CQ40-215wm that won't boot up normal but will go to safe mode, there I thought if I could go to an earlier restore point to fix it it might fix the problem so i did that but at 15 percent it would just shut down and each time it would shut down faster to the point I couldn't even go to safe mode.
After reading some of the forums I think this is really the problem but had to ask a pro.
The cpu fan isn't keeping the computer cool enough perhaps? It shuts down with battery power or power cord doesn't matter.Whats your opinion please? Clean the fan and heat sink carefully or if that doesn't do the trick replace fan?But it may take a tech depending on how its wired connecter or not? Hope you can help.
This must happen to a lot of folks. Thanks ken

Hi ken. initially the laptop was booting and staying on although while in safe mode,,that rules out the fan issue... i think the reason why its shutting off now is that the restoration didnt complete and so you basically have an incomplete OS installed,, i suggest the problem may not be hardware but software..u could try reinstalling the OS.. you could do this by either using the OS recovery cd that normally comes along with the compaq laptops,if not then you should have made it..i understand some laptops dont accompany these cds but they have an option to create them..hope you made urs.. also i strongly suggest you do not open your laptop as that will void the warranty..if the above fails,take it to an authorised dealer..regards

Just got cq56-115dx laptop this morning. turned it off after setting it up. Turned it back on and only have blank screen. Power shows lit up.


Hi.

Remove the AC power (charger) and then take the battery out. Plug in just the AC power supply and turn the laptop on, see if it boots up and shows a display on-screen. If it boots let it boot up and then shut it down as normal. Reinsert the battery and try as normal.
If you still get a blank screen can you then tell me if you get any post (splash) information like the Compaq Presario logo before it goes blank.


Good luck.

No power on will shutdown


Hello

First of all press ALT+CTRL+DEL and start Task Manager, there is probably some application (or other process) that is not reponding. You can kill them to let the shutdown continue, and know what is causing the problem and maybe find an update for it.

Also this means that your computer has not been rebooted properly since the installation of important system updates. If you have "Automatic Updates" scheduled on your machine, these updates could have downloaded and installed without your knowledge. To fix this issue, let the updates finish installing, reboot and then shut down your computer as normal.

Click "Start."

Click "Windows Update." Click "Install Updates" to begin the installation of any updates that have been downloaded to your Compaq Presario. When the "Restart Now" button becomes available, click it once. Your Compaq Presario will shut down Windows, finish installing the updates and then reboot your computer.

Click "Shut Down." Because the updates have finished installing and have been installed properly, your Compaq Presario will now shut down normally and will not immediately boot back up.

I have compaq pc presario c300 i cant open windows meaning when i start up my laptop the xp window is just come n go faster (popUp)


When you boot up press F8 function key and Windows will give a list of boot options, select Last Known Good Configuration and hopefully Windows will start up correctly. If not boot up again, press F8 and select Safe Mode and Windows should boot up in standard VGA display mode.
If this doesn't work you need the Compac restore CD disk that came with your laptop. Boot up with this CD to restore your laptop, you most likely will lose data.

Won't boot up, Hard drive self test result #1-07 Fail


Hi there.
The hard drive has failed and you will need to replace it.
If the laptop is under a year old take advantage of the warranty and send it in to be repaired for free.


Good luck and thanks for using FixYa!!

My HP Compaq Presario v2000 has new mobo, new CPU


You probably put more than a pin-head size drop of heat grease compound on CPU, thus "bleeding" over on the CPU, effectively overheating processor (very common). In any event, your problem is overheating -that's *the* place to look for now.

Desk to computer shut down problem


Go into safe mode and then go into MSCONFIG and click on the startup tab. You'll see a bunch of checkmarks in boxes of all the programs that are running. Disable all of them, and then restart the computer and let it go into windows normally. It it boots all the way normally then that means you had something running in the background that was causing windows to shut down and you'll have to figure out which program it was and uninstall it.

Compac presario R3000 problem


That screen is normal but only shows on certain occasions. Just use your arrow keys to highlight "Start Windows Normally" and press enter and you will continue to the blue sign in screen. If the removal software asks you start Windows in "Safe Mode", then restart the computer and select "Safe Mode with Networking".

Most common method for receiving that screen and those options is pressing a specific key during start-up for additional start-up methods. Another reason which may be the reason for your case is that something went wrong during start-up. Just follow the instructions above and it will be fine. Usually the reason why you are asked to choose is shown at the top of the screen and it will tell what the problem is.

Compaq notebook won't boot up


Hi

When you boot the computer back up go into Safe Mode and check to see if you can roll the computer back to the point before you installed the software.

If so this should work. If it works then run a virus scan, a defrag of the hard drive and cleans the temp files.

OR

You can do a diagnostic startup and uninstall Onecare. So once that it is uninstall ed it should be smooth sailing.

Here is a link for some startup / diagnostic software you could try after booting.

I hope this helps
