My hp pavillion dv7 keyboard lock lights keep flashing; at one point the computer didn't want to boot up; I finally got that up today after six months. But the cap lock and the number lock lights still...

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 not functional
LEDs blink 2 times
BIOS corruption failure (RTC coin cell dead)
LEDs blink 3 times
Module error not functional
LEDs blink 4 times
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 authentication failure

Blinking lights onlywill not turn on.

Blinking lights means 2 things. A bad power supply. 90%. Or a bad motherboard Kevin.

Computer won't come on but the power supply in the back does.

try unplugging the power, holding down the power button for 10 seconds, then plugging it back in and pushing the power button. If that doesn't work, try replacing the power supply.
