BATTERY AND POWER LIGHTS BLINK; BATTERY WON'T CHARGE..

overheating issues,

If you want to keep your important data, use some softwares can solve thewindows won't startproblem most quickly, and no data will lose. Besides, it is very easy, even the people who lack of computer knowledge can deal with windows won't boot issue.

If the laptop battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all. OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time. If the battery drops to an unacceptable charge level then the battery needs to be replaced.

those are POST code, error codes, you need to watch time and count them. report them.
leave the battery main out.
does it run ok now? yes/no.? main battery out?.
even new cheap batteries fail easy and hard and short out.
test it with no main battery. it can run on AC power for ever.

are you going to run the COIN cell RTC battery for 10 more years.
it wont make it..
this PC is 10 years old today (can be) so is RTC battery end of life. most fail in 5 to 7 years, says the pink bunny. (and is correct)
the manual shows how to replace it at the real HP Site,
fixya is not hp, not at all.

page 63 shows the way to the RTC

if you power on the PC, and hammer the f10 key]
BIOS runs, its menus;
check the time and date here, if wrong the RTC battery is dead.

read page 3 how.

• old PC have many points of failure (endless it seems)
• does the fan run? is it packed in lint, as all are this old.?
• causing it to overheat?
• RTC coin cell bad.
• main battery bad. (just leave it out until the PC runs right again)
• power pack wires broken, or running real hot.
• HDD going bad,
• windows infected?, no OS stated but avoid XP.

HP caps lock POST blink code page is a horror of horrors
no 2008 listing, to name one flaw (2011 and newer sadly)

here is a old post at HP, one guy 3 year ago said

LEDs blink 1 time
CPU
CPU not functional
LEDs blink 2 times
BIOS
BIOS corruption failure (RTC coin cell dead)
LEDs blink 3 times
Memory
Module error not functional
LEDs blink 4 times
Graphics
Graphics controller not functional
LEDs blink 5 times (or RTC dead)
System board
General system board failure
LEDs blink 6 times (or RTC battery dead)
BIOS
BIOS authentication failure

This is an obvious board issue if your not getting any lights at all battery blink or HD lights no screen BIOS board is dead, you may want to check to see if power is going from the plug in plastic pin on the board as well the plastic input pin may be solder split or cracked and not connecting.
So the obviously fix for this is take it in to a tech and have them test the board out to see if your getting power to the power button. If your not getting anything showing with even the battery charge indicator and all black out. Board replacement is inevitable, I dislike being the delivery person for the bad news. This does happen...............John

Sounds like your battery is just too dead, has enough juice to light up the system for a minute but cranking drains it and if it wont charge then deff fried, you could try removing the battery and starting the car with cables to confirm the starter still works. If a bettery is too dead then when you are jumping it, it takes to much of the power just trying to get through the battery.

> orange steady battery light

It will turn GREEN when the battery is fully-charged.
Is there a problem with the battery not accepting a charge?
Remove the battery, to see if the computer will start without it.

> power button lights shift key and 2 function lights

Do these 2 lights just "blink" once, and then go out?

Does a "power" button stay lit?

Have you hired a professional computer technician to trouble-shoot?

Try removing your battery pack. Then connect the power adaptor (even without the battery) and connect is directly to the power outlet. If it powers up, then the battery pack might be defective or totally drained.

If the battery is just totally drained, simply place the battery to the laptop. Do not turn the laptop on. Plug the power adaptor to the laptop and plug it to the power source. If you see that the charging LED is blinking in your laptop, then just leave it charging up to 5 to 8 hours.

Never use a laptop on battery mode while it is plugged in to a power source. This is the number 1 reason why laptop batteries don't last longer.

change battery

Just had this problem with my Guardian Aspire. They had to replace the electronic box with the joy stick. BIG BUCKS!
