I have a Compaq Presario V5000. The screen is black when turned on. (I know the screen itself is good.) My computer works fine when hooked up to an external monitor. I’ve tried locating a loose connection to the screen by disassembling my laptop. Everything seems to be connecting fine. Can anyone help? Is there an easy way to toggle between external monitor and the laptop screen?

tom kb,

only half the screen works the lower half is just dead pixels, but if you press the bottom right hand corner of the screen the lower half works (just while pressure is applied). this makes me think there is a connection problem so i have disassembled the whole laptop (thank you for directing me to instructions!) but dont know what to look for (was hoping to find a trapped wire or something, but everything seems in order!)

anyone any ideas?

Your description sounds like a problem with the LCD screen, not the cable or wire. You’ll have to replace the screen.

Moose,

I have been having issues getting my Compaq F730 started. Over the last couple months, I’ve had about 5 times where the computer will not boot.

It’s possible that one of the memory modules is bad. Try removing RAM modules one by one. Test the laptop with each module separately. Try installing RAM modules into different slots.

I have been having issues getting my Compaq F730 started. Over the last couple months, I’ve had about 5 times where the computer will not boot. After pressing the power button this happens:
- all indicator lights on the front light up
- nothing is displayed on the screen, and the HD light never goes on again
- fan runs
- if DVD is in drive, this spins up
- after ~20s the laptop shuts off and restarts.

To troubleshoot the problem, I’ve tried this:
- take out HD and put in another computer. The other computer read the HD fine.
- boot with a linux or windows boot disk (it started once with the linux boot disk, but I think this was a fluke as subsequent restart problems were not fixed by this).
- start with battery only
- start with battery out (AC connector was lit up, so I don’t think it is a broken connector problem)
- pressing F10, esc, del after powering on. Nothing shows on the screen
- shut the lid and reopen it. (If I remember correctly, sometimes the light on the front went off after doing this, but this may have been when I was testing without the battery in).
- hit the computer
- reseated the RAM chips

I’ve gotten out of the restart mode before but it seems to be random.

hi, there are a few comments regarding broken screens but no answer- hopefully someone can help me here-

i have a compaq presario c300. only half the screen works the lower half is just dead pixels, but if you press the bottom right hand corner of the screen the lower half works (just while pressure is applied). this makes me think there is a connection problem so i have disassembled the whole laptop (thank you for directing me to instructions!) but dont know what to look for (was hoping to find a trapped wire or something, but everything seems in order!)

anyone any ideas? cheers

Ronald,

why I can not get the internet working on my presario 1500,it says that I am connected. But thats it.

There is no simple answer to this question. Could be just wrong settings. Are you running Windows XP?
Try this:
Start>>right click on My Network Places (in the right pane)>>Properties
Right click on your network connection (wired or wireless)>>Properties>>Highlight Internet Protocol (TCP/IP) and click on properties button

In the General tab you’ll see settings for IP address. This settings have to match your router/modem.
In most cases it should be set to Obtain an IP address automatically. Is it?

I have a Compaq Evo N1000v, which my grandfather gave me. It has a locked bios and unfortunately he does not have the password. How can i reset the bios?, Can i take out the rtc battery and let it sit for a few days to reset it? Or is there another procedure. Thanks

Compaq Evo N-400c: I waited over a full week, finally put it back togeter, replaced the RTC battery battery, turned it on and pow.
Asked me for the power-on password. Anybody need EVO 400 salvage parts? It is not worth replacing the mainboard.

You have a great web site. Keep it up.

Evo 400 reply: Thanks for your prompt response. I am going to leave the batteries out of the Compaq for a few more days just to see. I read somewhere after making the post that the password may be on an EPROM that is erasable by UV light, so I left it out in the burning South Florida sun for 6 hours. You never know. If nothing else works, then the EVO is getting shipped to the trash heap. I will keep you informed. Thanks again.
