dead PC,
this failure and all cures have been posted here 100s of times.
even 1000 times. ive done 1500 now dead pc's.
  • what are you asking, ?
  • how to fix it
  • or what's wrong from morbid curiosity?
  • or want to learn how to fix PC,
  • or who can (any PC repair shop on earth, yes)
  • id bet no store fixes 11 year old PC, store? repair shops sure.
the book on your PC shows it is 11 years old now. 2007 made.
most PC this old are dead an parked in an attic, most.
you skipped step 1. and is...
remove the dead shorted many battery, non last 11 years.
not one. (if im wrong we do a guinness world records interview)
lol
so remove it and see if it works now.
step 2 is the screen, all old PCs 2010 or older (most then all)
have CCFL lamps that all died long ago
and the screen is black forever now, all do that every one.
if USED every day.
if the screen never shows text ever ?
then the back lamp is dead. (battery out, AC pack connected)
yes> black.>
then we do the flash light test next,
if you see data now, then the CCFL are dead.
99% tubes bad or 1% inverter that runs them dead.
in 2010 this ended with LED, your PC is NOT LED.
http://pcdied.com/monitors.html#flashlighttest

if the flash light test fails, NO DATA there.
then 2007 PC had the solderball from H3LL failures.
GPU grapics chip from Nvidia are bad.

the kiss of ***** here the fix is 10x more that the PC is worth.
value dead is $5 this old.
http://pcdied.com/monitors.html#solderball_hell

and for sure a new coin cell most are dead at 11 years.
and can cause all the above.
read page 44, its childs play fix.

Send the computer back for service if its in Warranty.
Try to use the Audio out on the side of the computer. Plug any external speaker into the port. If the sound you hear is the same as what comes rom the speakers then the sound module on the motherboard is defective. If the sound is normal, then the problem is in the wiring to the internal speakers.

restat?
stacked?
i have no idea these words? elaborate please .
tell what you do right and it does, wrong (a story)

my wild guess is the touch pad is failing
and no usb mouse attached,(hand held mouse)
that?
what OS is this , XP?

The mouse pad can be bad.
so can the mouse pad driver be corrupted , missing or wrong one installed.

start by telling the helper what OS,
click the (CP) control panel, click system'
the OS you run is presented to you there, in words.
windows what.
then CP (again, then click device manager)
under "Mice and other pointing devices."
see the mouse pad there, the driver there must not be
missing
or red or yellow marks ore UNKNOWN.

there are more tests and actions, but I stop here,
or get it repaired in a PC repair shop. (captain obvious sorry)

yet another old IPAQ, PDA.
why not ask HP
warning most have not seen one in 10 years, and forgot.

why own any legacy device like this, retired.
why not upgrade.?
nobody uses this thing> parts are not found. support zero.
value is like $1 at a garage sale.

did you ask the maker of micromedex if they even support this app
or if it even works in that mode, that be like first.

Compaq Presario Modem/NIC Combo (212786001)

we have no idea at all what you are running there at all
NO PC stated
NO OS stated (xp,vista/w7/8/10, why?)
An AT%T what? what modem exactly so they did not set it up for you ? no way they would not do that after all its' their modem and you run it from them as a service.


does your unstated PC use Ethernet cable Cat5/6 to the At&T modem or router? that is the fast way to get internet
fastest, most easy, and just plugs in.
your post lacks all key facts,
sorry.

Phone Crucial support. They know everything about memory. Sometimes there are three slots and only two can be used. Sometimes if the memory is over a certain size you can only use one RAM module, or if you use two modules, they have to be identical and matched. The other consideration is type and speed.

So I go here
RAM Memory Upgrade for Compaq Presario 2190US Laptops

you have two slots and the max is 1GB. You need two of these at 9 bucks each.

512MB Module512MB-DDR266, 266MHz, PC2100, 200p SODIMM, 2.5v, Sync 552ms-156 What have you got? Click COMMENT under my post.

Hello,
Check Lamington road Mumbai

Compaq Presario... | 128 views | 0 helpful votes


are you at home or Starbuck? location matters.
so, the compaq must be setup correctly.
your router broadcasts the SSID name seen by you on all devices, see that on the Compaq (y/n)
then you must pick wep. or wpa, or wpa2 encyption mode.
as set in your router, we cant see inside you router only you can
then set the passphrase to what you router wants.
is this XP, windows
does the wifi chip look ok in device manager?
Is XP infected.? with malware as all are now.

never post about computers lacking what operating system you have, or answers will be wrong, even all answers.

fixing a relic 15 year old square laptop, to want ends?
its junk now, the CCFL inside are useless now, too old
never spend cash on any monitor or PC with CCFL back lamps.
$$$$$$$$$$$$$$$$$$
"came ,up"
who came up.?
bios or windows. told you this?

sure wrong RAM.

finding ram to fit and work in any relic PC now is not easy
they dont make them now so are new old stock.
why not buy a PC 2010 or newer, used.
work that a end.
with hope and a real future.. yours is no good. sorry. but that is a fact, never throw good money after bad.

why are your using DELL any thing on any HP>??? so wrong that.
there is no free anything, (even lunch) for sure not any OS,
no OS stated btw, windows what? (guess at VISTA)
my guess is you want this old dog to run!
an 11 year old laptop.
HP does not sell HP media recovery kits for this old pc. (CD kits)
nor does Microsoft. now. (only w7 and 10)
this PC came with Citrix, OS or windows, VISTA 32 or 64.
Vista is now officially dead at MS, and at HP.(see exceptions)
HP does not sell vista disks, but the drivers are supported here.
as are manuals there, still there, lucky you after 11 years.
hint soon to be gone.! (10 year rule)

This depends what version of Windows you are running, if you are running an older version, say Windows Vista, there is a known bug with the ISATAP Adapter, essentially it is an IPv6 protocol, and is not needed. It should have no impact on the operation of your wireless card and is completely fine to use with the yield sign. It may have been there for some time before you noticed. The connectivity is most likely unrelated. If there is a yield sign next to you wireless adapter i would recommend re-installing the driver. You will need to search google for the driver and re-install. Sometimes manufacturers will have drivers on their websites and you simply enter you laptop model and year and select wireless card. Other times you will have to do a thorough search on google. Dont download any program that will search your computer for missing drivers, they are a scam. Try searching for your model number and Compaq. If you cant find exact model number of your laptop, a general Compaq driver may work.

Can you still connect through wired ethernet cable? What do you mean by wont connect? Do you mean connect but there is no internet? Or you can see the wireless network but not connect? or you cant see any wireless networks at all? I have also run into issues where the saved network configuration is corrupted, and trying to join a network and enter the password is futile, even though I have previously joined and it is a trusted network. In this instance, I deleted all network settings and all saved configurations associated with this network and joined again from scratch, which rejoined first time.

no PC model stated, at all... wow, 1984 to 2014 compaqs.
wow.
the PSU is bad if the jumper wire test fails
easy as eating apple pie, do that test. the voltages in the PC case are safe, 12vdc max. (no do not short out power rails.

NO the ATX spec is published in the wiki
the first compaq are 20 pin then later 24
so ill do 24 , just wild guessing what PC model you have.
why must we beg model PCs'
its like saying a Have a FORD car, what ford what engine, see?

jump 16 to 17 (17 is ground)
do not hot wire power OK (good) pin 8,
do not or blow up a good PSU.
never hot wire anything you do not understand
in this case the pin 16 has pull up resistor 5k, in all PSU made on earth. and you ground it (0v logic) to tune power on.
see the schematic in this page, do not blow up IC2.
or you will be sorry, I promise.

http://www.pcdied.com/power.html#Jumper

this works on all PSU made ATX spec. per wiki.

This will only work in windows. Most computers have another video out port other than vga. Check your computer and use that. You may need to buy an adapter.

Compaq Presario... | 123 views | 0 helpful votes


does the appliance have a dchp ip address option or auto ip address option. The IP address is used by the wireless network to identify each computer device in your house.
In your wireless router there will be a dhcp server that will lease out ip addresses to devices automatically.
the ip address would be 10.0.0.1 for your router or 192.168.0.1 usually most used ip addresses .
A subnet mask is usually 255.255.255.0 which is also needed.
Go to your desktop computer and go to command prompt . Google your version of windows and command prompt to work out how to do this.
then type in ipconfig
press enter key
note the default gateway address and the desktop's ip address
you may need to enter the default gateway ip address into the fridge also.
if the desktop was 10.0.0.2 subnet mask 255.255.255.0
then make the fridge if manually have to set it
10.0.0.254 subnet mask 255.255.255.0
or 192.168.0.254 subnet mask 255.255.255.0 if it is 192.168.0.2
the first three numbers are called the network address eg 192.168.0
10.0.0
the last number 1 - 254 are individual address part
192.168.0.1 {router uses this 1 usually } to 192.168.0.254

no PC stated, (model)?
no OS stated, windows what.?

that means the drivers are wrong for this PC and its unstated OS.
you do know compaqs go back to 2001
and hp portables back to 1984,
we can not guess PC models, and they are not all the same.
or means corrupted OS, or virus infected or worse.

the word compaq means little and the name ended in 2013
