Compaq Presario CQ50-139WM. Installing new DC jack, using existing wiring harness

Need to know how to attach wiring harness to dc power jack connector socket - cannot locate wiring diagram

You should buy the dc jack replacement that has the cable already connected, there are no wiring diagrams available.

Install new OS, but use existing User folders

I'm going to buy a SSD for my Mac Pro. I would like to install a fresh OS on that drive, but use the existing User folders on my HD.
I assume there's an easy way to do this, but I *suspect* that the install will make default User folders and accounts?
Any advice?

If you are the only user of your system you may be able to do this fairly easily. If there is more than one account it still may be be possible but there's a potential "gotcha".
If you intend to keep your home dir on a separate drive from your boot ssd, depending on how many of your own apps and data you intend to put on the ssd for faster access you really only need a 60GB to 120GB ssd. Assume the OS itself will need up to about 25GB of that ssd.
Assuming your are the only user then install the new OS on the ssd and create an account with the same account name of the one you had for the original system. Once that is up and running you can use the standard procedures to move an account to another drive. In other words use the Account system preferences to modify the account (account's Advanced Options) home dir info to point to your old home dir on the other drive. In this case you don't have any current home dir to actually move since you intend to use your old one on your other drive. Now reboot. Hopefully your reboot will come up using your old home dir.
The "gotcha" here is the userid. If you are the only user it should remain 501. So doing what I suggest above hopefully will work -- "hopefully" in that it has to be assumed your old account also had userid 501. With more than one account, if your old account wasn't 501 then I think you are in for ownership problems.
If you try this don't even attempt this without full backups of your original home disk(s). Best you create a bootable backup of your newly created ssd too so you don't have to reinstall and you can revert it from the backup if something goes wrong. Doing it this way doesn't write to new ssd cells if you don't have to (I am always concerend about this with ssd's even with possible TRIM or garbage collection).

Compaq Presario CQ50-110US Laptop

I have the same mother board problem with my Compaq Presario CQ50-110US Laptop. HP's Customer Service is very disappointing.
My laptop is 1.5 years old, 6 months out of warranty. My first call to HP was unfortunately useless. Told too bad. Motherboard is about $400 to replace. I emailed customer service asking for help with the situation. I asked if they would split the cost of the repair with me, or offer me a discount to purchase a new one. My case was supposed to be escalated to a Case Manager that would contact me with a few days. After 5 days, I re-emailed because I had not been contacted. It took a full week before a Case Manager called me. Again, nothing they can do.
Despite the fact that the sticker on my laptop says, "Built to Last", I found their responses very disappointing. I asked if there was anything they would do to "keep me as a customer?" Again, they will do nothing.
I explained also that I will be buying a new laptop, a new computer for my current business and another computer system with in the next 6 months for another new business. In addition, my brother-in-law had bought the same lap top as mine based on my recommendation. Again, nothing..no response or no help.
Since HP is not willing to make any attempt at all to keep my as a customer, I will be purchasing a new lap top very soon made by DELL. I will also not buy any more HP Products for personal or business use. This is not based on my defective lap top, but on HP's poor customer service and willingness to keep a customer.
My case # was 7501314351

connect an external display to test the video . Power it up and see what it does.
Consider performing a hard reset.
Remove the battery and unplug the DC power adapter.
press and hold the power button for more than fifteen seconds.
plug in the DC power adapter (leave the battery out for now)
press the power button

erico

MY Compaq Presario CQ50-105EE Notebook SHOWS: !! 0XC0190002 !! 1223/49793 (nshhttp.dll) AFTER UPDATING FOR PACK 2 AND STOP DURING THE INSTALATION. I AM USING VISTA WINDOW. THIS WAS THE LAST RESULT BEFORE I RE-START TO RECOVERY

I would use the HP recovery discs to re-install Vista.

Compaq Presario cq50, power.

A while ago, I had a problem with my laptop, caused by several updates. Suddenly, it stopped working, (battery was ruined), and I thought the power cord was the problem. So I bought a new one (according to the specifications of the previous one). And effectively, it worked. Nevertheless, after a few minutes, it shut down, and the light located next to the power cord entrance was blinking. I tried to turn it on again, but it was no use. The next day, I turned it on again, worked, and after a while shut down.
I opened it, the fan was relatively clean, and everything looked normal.
What do I do?
I could work without the battery before, so I do not think that's the problem.

Hi @FermiEffect ,
Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue about your Compaq Presario 50 and issues with your AC adapter. What are the specs of the adapter you installed?
Yours is 65-W AC adapter and should not be a travel adapter.
Plug the power adapter directly into a functioning wall outlet. Do not plug it into a power strip, surge protector, or secondary power source as this could cause and issue.
Here is a link to troubleshoot the Ac adapter.
Hope this helps.
Thanks.

Compaq presario cq50-215nr Battery melted

I have a compaq that was runnig great then the battery section on windows vista had a red slash tru it.
I pulled the battery out and it has a burned in hole in it.
I think the battery shorted out
Any body else had this problem ?
Thanks I am a disabled vet and unable to afford a new battery

I don't know what your budget is so I shopped batteries for the CQ50 on amazon.
I found a genuine HP battery for about $50 shipped a good deal, its $130 on the HP site
There are plenty of real cheap knock off brands for under $20, but who knows what the quality is or if they will last very long before they die or catch fire.

I am trying to take out my fan in my Compaq Presario CQ50 but I can't access it....?

I am following this guide (http://www.insidemylaptop.com/remove-mot… and I skipped removing the memory, WIFI, and DVD. I don't want to do all that. Right now I am at the part where you take over the top cover but I can't get it off. Do I have to go through removing the memory, etc; ???

- 4 days left to answer.
Additional Details
I have to either replace it or clean it. I can't just take out the screws in the back (it doesn't look like they come out. I was trying to unscrew one for an hour.)

If you were having your appendix removed would you want the surgeon to skip a few steps? Follow the Service Manual would be my best advice, sir. I have not personally taken apart CQ50 but there are likely screws inside the memory compartment or under the optical drive that can only be reached by removing the memory, DVD drive, wifi card, etc. If you do not remove the wifi card and antennae leads the antenna will be in your way holding the top and bottom halves together.

Does anyone know how to tighten the hinges of a compaq presario cq50 laptop?

I've had my laptop a couple years and the screen has become a little loose. I just want to know if there are any guides out there about how to tighten the hinges (screws in there or whatever). I'm pretty tech savvy, don't feel afraid to use big words

What exactly is this "text divider"?
A graphic? If so what format?

Would this hard drive be compatible with a Compaq Presario CQ50-115NR?

I'm wondering if this hard drive would fit in and be compatible with my laptop:
http://www.wdc.com/en/products/products.asp?driveid=684
I'm not sure if this 12mm, 2.5 inch drive would fit in it or be compatible with it. I plan to purchase this one if it is indeed compatible and will fit.
Otherwise, if not, then can someone recommend another internal 750 GB SATA 3 Gb/s 8 MB Cache 5200 or 5400 hard drive for me that is just as good quality as Western Digital? Must be compatible and fit.
Thanks and much appreciation in advance.

Hmm... Can no one help?

SPECS FOR NEW MBP HARD DRIVE AND HOW TO INSTALL NEW OS AND USE TIME MACHINE

I need to replace the hard drive in my early-2006 1.83 MacBook Pro (15-inch), because the Genius at the Apple Store told me that I'm getting weird behavior on it due to the drive slowing down and that it won't last much longer.
I have 2 questions:
First, I want to order the drive online and have it installed locally. I will probably get a 320 to 500GB drive. What are the exact other specs I will need to find the right one?
Second, I am currently running 10.5.8 and backing up with Time Machine. I would like to install 10. 6 on the new drive, but don't know how to go about using the Time Machine backup to get all my apps and files running. Can someone describe this procedure for me?
Many thanks!

Hi Annie,
You need a 2.5" 9.5mm high SATA HD, either 5400 or 7200RPM. Check out macsales, newegg, amazon to name a few places.
How to restore from a TM backup: http://support.apple.com/kb/ht1427
Prepare your HD by formatting and partitioning it:
1. Boot from install disc (press power button, immediately insert install disc and hold down c key).
2. Select your language.
3. Open Disk Utility from Utilities menu.
4. Select the HD in the left pane (the manufacturer’s name and the HD model number).
5. Click on the Erase tab.
6. Choose the Format: Mac OS Extended (Journaled).
NOTE: if you want to zero the HD (which I always think is a good idea, but does take time), click on Security Options, click the button for Zero Out Data, click OK. The larger the HD, the longer this will take, in some cases several hours.
7. Click on Erase and wait for the entire process to finish.
8. Click the Partition tab.
9. Click on Volume Scheme: and choose the number of partitions (normally just one unless you have other plans).
10. Click on the Options button (located underneath the Volume Scheme pane) and select GUID.
11. Click Apply.
12. Quit Disk Utility and continue with the installation process to install OSX or run Restore from a TM backup; when finished, repair permissions, run updates, repair permissions.

Problems with installing new hard drive using time machine

Hi,
I have a 2.4 GHz Intel Core 2 Duo 15" Macbook Pro (unibody) with 8 GB 1333 MHz DDR3 and a 250 GB Sata HD running OS 10.6.7.
It works like a dream.
However, i bought a new 1 TB HD (WD Scorpio Blue) since a) 250 GB is not enough for me right now b) warranty has expired, so new risk there and c) i read that installing it would be very easy.
I'll try so explain what i did, see if anyone finds what could be wrong...
I had some minor problem in the beginning (i didn't use the install disk of the macbook pro at first, because it was at the office, so i used the install disk of my old Alu iMac), but using the right disk, i opened "Restore Disk from Backup", selected the Time Machine disk, and waited for the target drive to appear. It didn't...
Finally i figured, maybe he doesn't find it because it hasn't been formatted yet (although it says on the HD that the Scorpio Blue is ready to use as is). So i openen disk utility from the utility folder and formatted the disk as "OS Journaled". As expected (?) the disk appeared as a target Restore Disk. I selected it and "restore" started. It took some hours and finally i receive a message: restore complete (or something like that). But then... after the restart i say the apple logo (as always) followed by the 'i don't know how you call it'-screen: a grey screen coming down like a curtain that says something like: you have to hold down the power button and then press it again tot restart (in a dozen or so languages including mandarin or japanese...). Off course i tried to restart several times, always with the same result.
I switched back to my old drive and it still works like a dream ;-)
So now i'm typing this message, can someone point out to me what could be the problem?
Some more information/possible causes:
- i run snow leopard, but the install disk is leopard. Maybe i should have used the install disk of the Snow Leopard i bought?
- the time machine backup backs up EVERYTHING including an external firewire disk (on the same disk). Maybe that could be a problem? I don't know if the backup disk will restore the content of my external disk to my new internal HD or not...
Thanks for helping me out...
Best regards,
Tom

Hold on... it seems like i missed the obvious answer: using snow leopard to re-install a snow leopard back up. I'll try that one first and if it doesn't work i'll come back to this discussion...

How to install new card to the existing 15454

i have new cards which is CISCO 2.5Gbps Multi-rate DataMuxponder 4ch 1558.17-1560.61 (15454-DM-L1-58.1=).
if i install to the existing system, is it will affect the system?
do i need to reconfigure the existing system using DWDM metroplanner before install the new cards?
what are the correct steps to install the new cards?
thank you

Hi,
Answers to
1/, no it will not affect your system as these cards are hot pluggable, and as long as you insert into the right slot (refer to the Cisco documentation)
On this Cisco web page, http://www.cisco.com/en/US/products/hw/optical/ps2006/prod_installation_guides_list.html
2/ you should not for minor card addition like this.
3/ you will find the procedure document for the applicable rel of ONS software you are running. The procedure will have a section that documents steps to install various card type.
Hope this helps.
cheers,

Installing new RAM: Compatible with existing RAM?

I've just ordered 8G of memory, 4 lots of 2G. I have 2x1G on board already. Will I need to uninstall the original RAM, or will it work happily with the new RAM?
Secondly, I see a warning in the Apple installation document that I need to remove the battery to get at the memory slots, and that replacing the battery incorrectly could cause an explosion. Seriously? I'm nervous enough just installing the RAM. I could do without explosions.

Depends on the manufacturer to be honest. I have 2GB of original RAM in my system with 10GB of OWC and they play happily together. I suppose it still holds true that you "get what you pay for" - they're not the cheapest, but I didn't break the bank.

I honestly did not see that warning on my 2008 Mac Pro and simply powered down, unplugged the power cord, took both memory risers out and installed the modules per the instructions of OWC (Macsales.com) - Kappy has posted those for you.
I've had them in for a couple of months now and couldn't be happier. I would suggest following Apple's instructions though, it could prevent serious damage to internal components caused by electrostatic shock.
