old CQ60s. (had?) have,
staples has real techs? really?
no they are just guessing, for a fact , if they did not do tests.
then they are (guessing or ignorant hacks)
first off CQ60s have a full model number like CQ60-100
never post lacking that, and the OS name like XP, or all answers will wrong.
so big battery out.
new power pack added for $8 new.
power on, fan must blow air, if not blow, clean first.
never seen any 10 year old PC or laptop not be packed in lent
causing overheating so easy.
the fan is first, then make sure the CD eject works
the what is next, the dead coin cell RTC/CMOS battery inside all this old are BAD< how can it be good this old ,it cant (unserviced PCs')
then with that replace and at 2.9v to 3.3v. you see
screens work you see text now. from MR BIOS
MR BIOS always works if the CCFL are not dead.
ever heard of CCFL , they ended just after the great year 2010
and LED was born,
But CCFL black lamps all fail, this old.
all do. as do HDD, Coin cells and all those old huge batteries.
leave the battery out now, big one. until the PC works again.
then get the screens working (hit F10(ESC) to enter setup)BIOS.
seen that hit message for 10 years, right, sure.
the goal on all PCs it to get that HIT text. there.
lets do you a list.
- big batteries out. NOW , keep those DOGS out !!!
- AC pack out. (disconnect)
- hold power button for 10 to 30sec. and release (HP hard reset this is HP magic test on every hp page.....!!!)
- AC pack new back on PC. laptop
- power on, fan must blow, if not say so... now. (stop and ask )
- Power on fan is ok , screen is 100% black no text.
- got beep codes? or Caps lock led blinking codes?
- BIOS is dead, hammering the ESC or F10 key as it prompted you for 10 long years, but is BIOS dead now. (no HIT)
- new coin cell is next per your manual , ask. called by HP the RTC coin cell, search RTC in the service manuals of all HP PC. (real time clock) and if dead BIOS GOES DEAD.
- Next, the flash light trick if the fan works and no text we do the flash light test, OMG the back lamp is dead !!!
