Question about Compaq Armada E500 Notebook

1 Answer

Purchased a Compaq Armada 7800 from a pawn shop. The power cord plugs directly into the back of the machine with no adapter. Does this machine have a built in adapter? Does it have a battery? I dont see where the battery compartment is.

Hi. Yes, it has an "Integrated AC Adapter for less bulky transportation; 8-foot power cord included"

It also has a Li-ion Battery Pack on the left side which provides over 2 hours of battery life - if its OEM, but there are higher capacity batteries you can get for it at amazon or eBay .

This Link will take you to HP's page for more data and diagrams on your machine.

I have tried to recharge the battery and when turned on it just keeps beeoing is the battery bad


A fast check to determine whether you have a problem with the power adapter, power cord or the laptop's battery is to turn off the laptop, remove the battery, connect the power adapter, turn on the laptop & see if it works.
If the laptop works directly from the power adapter with the battery removed, then the power adapter is good. In this case we can suspect that the battery is defective.

My compaq armada 7800 display is very poor


It's probably the lcd, but it could also be the GPU, lcd cable and or the motherboard.

You'll have to have a local tech check it out to verify the problem.

Crashed HD and now way to get to BIOS or BOOT SEQ.


When you power-on the computer, does anything display, such as the amount of RAM, or "press DEL to enter BIOS setup"?

If not, then you have a hardware-problem with your computer;
the "good-news" is that the data on your hard-drive is OK.
If you connect the hard-drive to another computer, you can "rescue" your data-files.

AC Adapter


It should have the power cord as according to this page courtesy of HP:

http://partsurfer.hp.com/cgi-bin/spi/main?sel_flg=partlist&model=ARMADA1500&HP_model=291450-007&modname=Compaq+Armada+notebook+PC+1590DMT+(291450-007)&template=main&plist_sval=ALL&plist_styp=flag&dealer_id=&callingsite=&strsrch=&keysel=%3F&catsel=%3F

They don't show a part number for the ac adaptor though which in normal circumstances you should get that to when you buy it straight thru HP but they may be out of them.

You can find one off of ebay and it does exist as according to this auction:

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&print=all&item=130303693439&category=31511

So definitely you can get one from Ebay if all else fails. Hope this helps you.

The screen on my compaq armada is blank. i can


The display panel itself is probably fine, but its backlight isn't working. Without the backlight you can't see the display. There's a small circuit board called the inverter inside the display that provides power for the backlight.

It's pretty easy to replace the inverter. You need to take out whatever screws are holding the front half of the display to the back and remove the front. The inverter is at the bottom of the display, held in by a couple of screws. A couple of cables plug into it.

Here is a place that claims they have the inverter in stock for $7.39. That is one fantastic price! Get one of those and a set of miniature Phillips screwdrivers and you'll be able to fix this yourself.

Compaq Armada E500 shut off and won't restart.


The notebook does have an overvoltage and overcurrent protection inside the computer itself. The problem is definitely in your low voltage power supply section of your notebook. Since you do have a multimeter and know how to use it. Take your notebook apart so that you can see the board that your power adapter actually plugs into. Your notebook may just have a normal fuse that you can see is blown since they do make that little popping sound and do not leave any discernible smell of an electronic component that burned or blew up so to speak. That you cannot smell anything like that is good. If you do not see a regular fuse, there are what are called bell fuses that look like miniature glass diodes or resistors but are actually inline fuses. Your entire notebook should not have more than two or three. Sometimes they are made of ceramic, but that is only used for high amperage uses like on plasma screens and such. If the fuse is visible and checks blown try another one and watch it as you power the computer up. If it blows again check your on/off switch without power to your computer to be sure it is not shorted out. Then trace your voltages into your computer with power on and see where you do not get any voltage down the line. It is pretty straightforward in tracing the voltage from your adapter into the computer. Remember though that the intial voltage from the adapter is broken down into smaller voltages for the logic circuits. It is apparent you are not getting any voltage past right inside your computer's power supply and voltage regulator section. You in my opinion have an open circuit instead of a short right now. If you find fuse and it blows again then you have to find the shorted component. Let me know and I will be glad to help further. Good luck.

According to the owners manual on the hp/compaq website, that notebook has an AC cord that plugs directly into the wall. Therefore the notebook must have an internal charger to convert the AC to a DC voltage to recharge the battery. Here is the link to see the manual:
