There is no need to take out the battery if there is power and the laptop gives sound .
Connect external screen to the laptop and see if you have picture there .
Also try to hold Fn button and corresponding button (f2 f3 f4 ....) That has picture of a screen on it , when the laptop is on.
If laptop is constantly beeping one or both memory chips are out ...
Need to charge the battery.
Step one remove the large battery first.
then run on AC power ONLY.
and if fails still? say so here. and we can do all 12 steps.
https://pcdied.com/dead-PC.html
if not?, not.
PCs mobile all fail. for the big battery first.
so take it out.. easy no? just one test. and vast PCs start working
for the wonders of MR battery loves to fail. or worse short.
the PC is 7 years old
what fails on PCs that old
the big battery is NO GOOD.
run on AC pack only for ever
or buy a new battery,
the tiny coin cell will fail next, 7 year to 10
years is the time I fails. (spec is 7 life)
we get a tone ?
if that is beep code , then not a tone
but a message, just like Samuel Morse invented MOrse code, we have beep codes.
just have new meanings.
newer PCs got rid of the beeps.
but some PCs the tone is solid,
this means super bad power failure.
we cant see your screens nor hear it so...
we can not be sure, computers are not simple.

Pull the battery and disconnect the power cord. Press and release the power button. Reinstall the battery. If the laptop still won’t power on either the screen/backlight is dead or the motherboard has failed.
no don't put the shorted battery back in
yes do the long reset.
so you got it 1/2 right
you do know the batteries short and overload
the internal charging chip and the power regulators, right: this is power 101 school here, need lesson?
lie 2, is the motherboard is failed.
big lie there, bunky. (it's last not 2nd)
the correct answer is if the battery big is out the coin cell new and new power pack is tried, we then remove all options modules from the PC that any one can short out.
do you know how electronics work?
things attached to any motherboard on earth can short and for sure overload the VRM.
PC 101 .class ended.
Pulling the battery and hitting the power allows the capacitors on the MLB to discharge and the video card circuit to fully discharge as well.. The questioner has not yet determined the battery is shorted. It may be depleted/old. Despite your ego, you are not teaching a class.

Check with the place you purchased to see if you still got warrenty, also you can find the exact same model here or a new model at discount prices>>www.discountbargainprices.com
SOURCE: red light on power button flashes, but no picture....blank screen
I would suspect a problem in either the backlight assembly, or the power supply that drives it. If it's the power supply, the part may be over $100.

(N.B. I think there may be two variants of the Ultimate Plus, TR2500BC. They can be
distinguished by the number of rivets in the pan, 3 or 4. Mine has 3.)
I had a similar problem. Holding down the Reset button and plugging
or unplugging the machine didn't work for me. (Note: I've been
pretty careful to hold the Reset button when I unplug the machine
after baking a loaf.) This procedure worked for me:
1. Unplug the machine.
2. Remove the plastic keypad housing. There are three screws: left,
right, rear. (Note: One has a different thread from the others.)
3. Rock the housing back and forth to remove it.
4. Remove the white protective cover. It has two screws.
5. (You *did* unplug the machine, didn't you?)
6. Identify the ribbon cable and locate where its connector seats on
the circuit board.
7. The circuit board has little printed labels opposite each pin.
At one end are the labels GND, VCC, VDD, in order.
8. Short together GND and VCC with a small piece of wire by sticking
the ends of the wire into the top of the connector to touch the contacts.
9. Do the same with GND and VDD.
10. The machine should work now. With the keypad housing, circuit
board, and cables safely away from the metal body, plug the machine in.
You should hear a beep, and all should be well.
11. Rejoice, be glad, and make some bread.

Same Problem. I fixed mine with a baseball bat, hammer, and a cold beer. Lesson learned: NEVER BUY DELPHI AGAIN. NEVER..... Tell your friends. Delphi = POS

1. Take off the the power plug
2. take off the battery
3. press and hold the power button for 10-15 seconds
Now try turning it on, if it still doesn't work, check in your manual how to RAM cover, and take the RAMs out (before you do this repeat stpes 1-3). After the ram is out, try turning it on if you hear sirens , that could be at least some indication that your motherboard is alive. if no sirens --- than you got bad news.
So at least you will now if there is a chance if the motherboard is not dead.
SOURCE: screen will not turn on, power light flashes red
try checking first your tact switch or your power button, then next look for open fuses or low ohm resistor on secondary part of your power supply then check your horizontal and vertical outputs for shortage and open circuits check also your horizontal drive stage.

It is possible that your memory stick contacts are dirty or dusty. Try removing the memory access cover, remove the memory one at a time, and gently wipe the contacts with a soft cloth/can of forced air dust remover/soft dust brush.. Reinsert the memory & cover. Restart system.
