wow a compaq forum , HP is correct forum nobody reads this.??? post to HP folks , i just stumbled on this. wow are you a 1 PC shop,. cant try other PS with that PROJECTOR Desktop or laptop. gee? so simple a test, or move PC to projector direct, omg works. and custom cabling,?????????oops RED FLAG that is what is wrong, ever read the VESA spec, on this, its tricky (2002 worst year ever) if you connect that pc direct and it works well gee the cabling is wrong! no distances stated, 10ft, 100ft 1001ft, what? btw ive built these systems my self, even from scratch, (chips) later, late 90s on. they also sell pro grade, buffered VGA, controllers. even from 1 PC and 5 projectors, there are buffers inside that make the signals perfect at all times. NO DISTANCE STATED! do be aware you can not run COAX that far in most cases. facts. (ig goes blurry, sync weak or goes to sleep mode) only buffers work. (video band widths are wide and high) One other system sold is a converter that converts VGA or DVI to a custom data stream at the PC then decodes that at the other end for perfect signal. THERE. one famous company that I bought from was BLACKBOX.(tm) talk to them been using them since day1, before went public stock. https://www.blackbox.com/en-us/products/black-box-brand-products/video-multimedia

is this a CCFL LDC if yes the inverter is bad. (a card tiny, and thin) its old LT. the books are gone now. the service book tells you how to replace the CCFL inverter find a used good one is problematc. why not buy a newer LT or just run the external screen and be happy I guess you have not read the user guide yet? about the VGA hot key. mine has.: 1: external only 2: internal only 3 both 4: auto. (i think only my newer HP has this) mine is Fn+f4, but on a relic compaq, gee buy the book, or google search for it for weeks, next time post to HP< there is no COMPAQ for years. hp owns it. totally ever seen this before. the fail like LT batteries do. often. http://www.ebay.com/itm/New-15-6-Laptop-Screen-LCD-Inverter-for-Hp-Compaq-G60-G50-CQ50-CQ60-Series-/251312052451?hash=item3a835d98e3:g:ARYAAOSwal5YJoxR search there "compaq CQ60 inverter" bingo. when the sceen is dead do this. see the flash light here, BINGO? bingo for inverter *****? http://pcdied.com/black-screen.html#Dimbulbs

why not ask them, or other around you obviously using that. try to know, that each place you go they have rules. there are less wide open ad hoc networks now. do to folks doing ******* things there and the owner can be liable. first is range, its a weak radio, and if too far it cant work or is slow. you will need a password to get in. in most places here. at 1 air port, its password and my other air port ,they let you in PW free, but you must sign a page that tell them you dont break the rules that filters all your cruising, (has huge blocking of vast URL) that is the way of the future, blocks, rules and sign in PW. at one air port the password is on all vertical pillar in the air port. clear as day. UPS requires and account, all do. l get one, use it. unless doing tracking blind. sure. again next time at XRAY (a store, or whatever) ask them, learn to talk, walk to the counter, and say can i use your wifi, and how do I they will say , the SSID, the SSID is the wifi broadcasted name. you click that and enter a pasword most places do not run AD HOC now, sorry, but those days are shinking fast, the golden days of no rules. are over.

the beeps are called BIOS BEEP codes. and is telling you what is wrong. does run with no battery removed do the BIOS screens work they MUST at all time. power on ,hotkeyed. is the fan running its old right, like an old car that will not start do you buy a new car? or buy a new battery? hummmmmmmm ever heard of a tech>/? those folks that diagnosis things? tried taking battery out, but failed to say it would not run only on the power pack. take it out and leave it out for now... be wise. so the HP logo works every-time you never said that yes./no.?? thAT hp LOGO IS A BIOS LOGO FROM HP. if yes the BIOS is ok. see? means the brain works the Ram is not dead and if you had pressed the BIOS hot key F1,F1, Esc, F10 what ever it is , it tells you what at boot in text. if you look there. if it stalls with good bios that means. bad HDD or bad OS. SOME NEWER PC HAVE f10 OR F11 RESTORE KEY IF YOU Press that, at power on ,it goes to restore mode. (means reload windows) oops HP retired this PC https://support.hp.com/us-en/retired-products that means in English clear, its NOT SUPPORTED NOW. no books no software no updates no NUTTN No anything, ! now you know why mom dump it.? LOL !!!! its a dead fish. or FORD, found on road dead. LT. why not report the beep codes clear and accurately,?????????????????????? run the LT with no battery and level it like that till cured. then, replace the COIN cell, no laptop this old has good 3vdc coin cell, impossible I bet. if the cell dies, as all do in 5 -10 years. the PC beeps with CMOS clock, NVRAM errors. the battery size of a coin, runs the Real time clock and the CMOS memory bank for the BIOS settings. if the coin goes dead BIOS GOES NUTS ANT TIME/DATE goes NUTS. if the beep codes say the HDD dont boot that usually means HDD is dead. the trouble with beep codes are that there are many BIOS used and many codes used. some are impossible to find. beeps are now gone we flash LED codes now. this is DT coin, LT is warped in plastic and 2 wires. see the COIN? http://www.pcdied.com/coin-dt.JPG beep? 1 long , 1 short, ? is COIN dead. http://www.bioscentral.com/beepcodes/compaqbeep.htm note the black hole OF BIOS code HELL here, its a bad place to be. for sure. one other test is go to BIOS page. see that time/date, year, settings. if way off the COIN is dead. learn to that a 1/2 dead coin can work now, then file and 1 hour later work, that is how batteries fail. they go MARGINAL sometimes.

wow, no tests down with battery out. battery is the #1 failure in all laptop made. and fails many ways. the firewalls does not source power, forget that. If fact the HDD removed the power systems work perfectly. tests, run with no battery, IT MUST, if not the line power pack is TOASTED. runs with battery only, no, yes? (if charged) is this hard, no. try to know batteries can short. when they short they can overload any charger chip and can the PC. Batteries are week techology no battery ever lasts as long as the PC or any of its other parts. the fail some can fail in 6 months time. why wait, run with no battery, heck some do for years. after learning to hate batteries. I have 2 and is only for travel every year, i test them before for my trip for proper run times. only that works, in the world of batteries.

wrong power pack, ask at HP.com yet the real HP forum it not the pack then the power regulator chips are blown on the mobo. a vary bad deal that. the OS is not bad, the power runs even in BIOS and no HDD. the mOBO is what chargers the battery. there can be 2 chips one for main reg, and one of charge reg. the PC sees you plug in the power pack and see power from the A/c side go good, if not it goes to battery the chip does all That magic, not WINDOWS. what if the new battery was bad. (lots are, ever see the huge recall on batteries?????????) for GOOD REASON. I keep 2 good batteries from mine all the time., 2. There is no way to diagnose any charger chip with only 1 battery needs 2 good batteries to get hard evidence proof. If you look at you mobo and see those 2 chips there. mine is 8mm square, and is SMD chips you'd play hell testing that. no? the pins are underneath it. of the AC pack is correct, for Volts and watts then the mobo is bad, the switch over to Battery at AC power on, means the AC side is bad or weak, or the battery has shorted cell, did you measure your battery first with a voltmeter to see if one cell is shorted, as they ALL LOVE TO DO>?

why not ask sling this at their web site support/ this is a USA chat room , with little, UK help. goggle finds them ,no?

compaq presario C762NR wow, posting with NO OS stated, no Operating system stated. windows what?, OS2, Linux, what? be specific or help will not be correct. connecting. we don't know at all what connections you have, none stated? is this an Ethernet cable (cat5/6-RJ45) ? to your ROUTER? or wifi to your home router, what? if Ethernet cable works and wifi not then we know is wifi only. why not use a cable, buy one for $3 and keep it handy. btw , the cables allows getting long winded windows updates 100x faster. or if installing an new or updated or restore OS even faster. we have no idea at all what OS is there. nor if it was upgraded to a higher version without HP support. its and HP computer now, Compaq is gone. if you look in DEVICE MANAGER. see all net work chips there, ? are all of them happy, no red, no yellow marks or missing ? if yes, then your DRIVERS are wrong, or corrupted. that is step one, not get connected. get connected can not fix bad drivers. so DM is first. but first first is what , DRIVERS matching your unstated OS.

if the fan is dead and the old HDD is pure silent the power pack is dead. (battery out) no OS stated, then post questions, why> , why make it impossible to help>/ let me guess the virus magnet XP? or worse older? some are vista and w7 fitted... must I GUESS THIS? dead laptop 101, (generic) runs ok battery out, BINGO ! BIOS works? that is first not windows EVER, BIOS works. does it? you do know BIOS works with CD drive and HDD drive out right>? if not the power pack is dead, or the mobo regs are dead. you can pull ram sticks and run them 1 by 1 to see if one is toasted. there are many modules on all LT MOBO, that can short out. a tech pulls them. to learn that.. fact. bingo? what a tech does is strip it down to near nothing here to get BIOS alive again. if its goes live the fan spins, see? if BIOS is dead, all PCs made are dead. hopeless. BIOS does the boot and hand off to HDD< see? focus like a laser on BIOS....! and win. you typed the model wrong, so is now 2 times harder to help you. Compaq Presario CQ60-615DX Notebook PC HP has support but not software now, (sadly) https://support.hp.com/us-en/product/compaq-presario-cq60-600-notebook-pc-series/4074237/model/4121161/manuals its just a filler page, the service guide is NOW MISSING so i cant spoon feed you the BIOS hot key but the black screen page here tell it. F1, F2, F10 and ESC. If you boot a working PC (no hdd, no cd drive needed) you will get a text message. from BIOS telling the above, secret. every way on earth to get a black screen or silent pc or dead bios is there. (seems so) http://pcdied.com/black-screen.html

lines in BIOS means what, it means the screen is bad. end story. (or can be weak power pack, 19vdc 65watts(min) is it?) BIOS runs with no HDD !! runs with no CDRom, so that means it cant be OS related at all. ever. in this case. HP Pavilion dv2550se Notebook PC (my guess at true name)HP does not support W7 on this plateform.that means , you are only own STEAM, with drivers. but if all you need is one driver to work, you can get that , that the maker of that GPU chip.This PC CAME WITH VISTA ONLY. EVER.THE PC DAY1 had 1 chips offered, one intel, other nvidia. we PCI scan all hardware to find whats there,so can you , or ask hp for that fact by telling them your serial number, we are not HP here its just a silly chat room here.

compaq is HP so best is to ask them, there, now here. RTC error mean , the RTC coin cell is dead. all PCs this old are dead battery , RTC= real time clock chip says IM DEAD, but is battery dead ,.. remove the coin cell, and put in a new one. end story. then set time . best is to set time in BIOS setup. 1st. this Compaq is 18 years old now. or 126 dog years. id , push it off a cliff on the 4th July with fireworks. and all. let me guess its XP the VIRUS magnet. some this old are windows 98 a hopeless case there, no? no support, no books and no updates. the books at HP are long gone so now all books are , sold by horders. $$$ it can be costly and dangerous to deal with folks like that. the book you lost , , the answer is on page 18 seen here see coin, remove it and put in new one. end story. https://www.manualslib.com/manual/30167/Compaq-Presario-Presario-1255.html?page=21#manual

the display panel needs to be replaced

I would plug it into external monitor. it if works good on the monitor. could be bad video cable or lcd panel. video cables get pinched in the hinge or lcd get broken due to lack of support around the screen (poor design)

Please ensure that you have admin rights to install software on your laptop. Otherwise try creating a new windows profile and then install software.

Take out battery from laptop and disconnect power cable. Keep the power button pressed for 30 seconds and then plug the power cable. This will remove static charge from laptop and should resolve the display issue,

BIOS issues

Hello there Hints: 1) You got a driver or device problem, 2) use the drivers that cam with your f700 particulary these ones, 1) video card 2) sound card (sometimes if driver is bad, it can cause these problems) 3) RAM problems, to isolate the problem, if you have the expertise take ount one ram module at a time and turn on the computer. see if these helps!

you need to buy a notebook cooling pad, if you don't have one on your laptop. this can help to reduce overheating of the laptop..
