I bet you do not need or want any proxy server. I bet you question really is how to get internet connected, right? first off what OS is this, XP> we can not see you, your PC nor your OS. (whats connected to PC, nor if it has wifi options) is this IE11 your browsers , cant guess that either,? why not use an Ethernet, Lan cable CAT5/6 and plug in the PC to the router and it all works like magic, that be first. if the PCs lan jack (ethernet ) is dead. (and other PCs work on your router) do they./ then we go to device manager and look see that? then see if the lan chip has driver. network marked, red/yellow or unknown is bad. if missing the get it from HP. HP has zero support on old PCs, it's too old, its in fact 16 years old. support ended . 2007 (17-10 = x) came with 10/100 Ethernet, new (spec sheet says) slow. that is. but what chip that is , is very hard to find out this old why waste time and money on PC worth $5 used.? it came with windows 2000 or XP new. which is it? if the driver is good, or the unknown chip there, ethernet the when you connect to the router the connection made automatically then running relic old IE 6? you see proxy question tell it no, and that sets automatic , gate way ip address to your router. and just works out of the gate. install firefox v56 and its more easy. to run and not get bogged down in proxy settings. avoid IE versions below 11, as all OLD IE's, are virus magnets and zero support, use Firefox, on all old PCs, not updated to W7 !!! IE = internet exploder browsers) show just getting a connection, only. browsing is a whole other matter, and 20 browsers free are common. http://www.pcdied.com/DevMan/internet.html

As long as the battery is working, Windows 7 and up will see the battery when connected and treat your PC as if it were a laptop when it comes to power management. You will have an option in settings under Power Management that will allow you to tell the computer how long to stay on when it detects it's on battery.

Hi , I think your updates download has interfered with DVD driver that was installed in that machine ,I want you to try this look for installation drivers for the DVD/CD ROM and install it . The DVD/CD should work now .

a great post and funny to read about snagging wifi. lots of kids make a dish at school and use wifi from large distances. so you are home right,. not in the library , right, and now expect the Libraries wifi to be fast at home , that far away,. well it will never be fast ever. like that. if you have a router that is 2 bands, there is no better routers. the library only runs 2 bands I bet or even just 1. so why not buy your own internet service, or rig up this. https://mods-n-hacks.gadgethacks.com/how-to/make-satellite-dish-wi-fi-antenna-for-free-internet-291730/ you can use a colander from moms kitchen https://img1.etsystatic.com/202/0/5319571/il_570xN.1372655963_8crn.jpg or other dish shaped objects to make this dish.. they need to be focused. and pointed to the library to work. even card board, cut to a dish and aluminum foil works, all this is fun stuff, but never reliable. at night they can have there router go off, on a timer.

Sorry about this. Have you tried charging your tab to full capacity first. You need to plug it into ac mains and leave for a few minutes to allow the battery get some charge on/in it. Secondly, I am persuaded your tablet PC is windows OS (I stand to be corrected on this please). Was the system board confirmed fully configured/operational with all drivers installed? Aside of drained battery in need of charge or boost; suspected fault may have to do with getting your tab PC to initialize boot sequence.

its a bad pack why not buy one for $8 and not try to do hacking or worse? why think its not bad,? if you used a voltmeter at the mobo side, you know that it was or was not, ONLY! i cant see you twist things,? if the mobo jack is bad, on the mobo there are only 2 fixes for that. 1: buy a new mobo (or new PC) 2: buy the jack and solder it on your self. or a tech do that. here: 1: new coin cell RTC battery is first. 2: get the main battery out, the bigone they short and overload, the regulators. and the power pack. leave the big battery out , work better now??????? 3: try a new $8 pack. work ok now.? 4: ok we check the Jack next, at the mobo side. for damage common this is .. for sure something SO OLD. but is only 6 year old I see. not tool old but no spring chicken sure. RTC coin on page 53 pdf. http://h10032.www1.hp.com/ctg/Manual/c02985882 now i look inside for you,. reading your manual for you and see what./ I see this. lucky you, the jack is cable'IZED NOT the direct mobo type. https://www.ebay.com/itm/DC-Power-Jack-Harness-Cable-HP-Compaq-Presario-CQ60-203NR-CQ60-204NR-CQ60-206US/110962776204?hash=item19d5e5988c:g:I~QAAMXQs~ZRl7Mb see that. so if that fails, power is lost. easy no?/ no power no go.

NO PC stated, why post to lacking that key fact.? even the mouse/kbd is not HP. but are posted to Compaq /HP. its a wireless keyboard, and like ALL things like that has batteries, or it can possibly work. the mouse batteries. The keyboard batteries. are bad. replace them.. and drivers to make the unstated PC work with this wireless module. if panicked. use a real keyboard, USB, any one you find works and uses NO BATTERIES to do so, same with the mouse. that is step one, step two are the drivers. if running xp or vista the drivers will not come from Microsoft as they once did, so getting them will be hard. NOW ! XP is a dead product. but again no PC stated, no OS stated, no real help here, full.

XP is dead at MS. XP is a virus magnet, never ever ever use XP ever. again, like 99.9% of all other persons on the planet. we have no idea at all what you are doing after all where would you get XP , from some hacker pirates? my guess this PC is 10years old so says the service manual. this PC only came with VISTA 32 or 64bit. HP does not support XP nor W7 on it. that is official. to reload VISTA, power on and hammer F11 and VISTA magically fresh loads back to day one condition if the HDD is not bad. where is that XP at? on MS disc CD or USB stick on HP media kit disk bought long ago. and now not sold ! on some hackers web site, lots there are, and all full of virus and then you find the COA key is illegall. Id try to put on W7 and see if some things work. many things will not. that is what support is all about. that.

CQ-nnnnn what is nnnnn , may Cq57 made, all different nnnnnn QC-100,.-200.,300, 400, series your service tag tells you the full model number. nor the OS (unstated) XP, VISTA, W7 or W8? this is what was used for the full series of production runs. and they are NOT THE SAME. tell what BACKLIT means. LEDs dead but at least name ONE>? Please tell the helper this. what OS first.? tell exactly what Backlits (lights) fail, name them. caps lock or ? what? give examples of what fails and what you are attempting to do.. on my newer HP, there are no keyboard lamps at all not one but the HP has back panel that glows for that. but needs the HP software loaded to make that work only HP software works on that feature, period. what operating system is this.? the CQ57-400 is the last series is this it. why must i guess? support for it is limited to this. ill guess 400 for you as 1 example then ill guess w7 32b then you see this and load all these driver. https://support.hp.com/us-en/drivers/selfservice/compaq-presario-cq57-400-notebook-pc-series/5186820 now il guess 100 here https://support.hp.com/us-en/drivers/selfservice/compaq-presario-cq57-100-notebook-pc-series/5059083 looks like last one made was 2012 (Compaq ended in 2013 at HP) so has support until 2022. at HP.com load all your drivers for you PC on the HP page. skip BIOS. (line) the problem here is HP used 2 processors here. Intel and AMD mixing drivers up is problematic. here. takes skills to do this. why not ask at HP do this is. real HP forums.... BINGO? https://h30434.www3.hp.com/

NO PC stated (wow1) NO OS stated, XP, vista,w6/8/10? wow 2. that is a relic PS2, mouse, nobody use those now, and PS2 parts are unique to the makers, eg: HP mouse fits only HP PC. so.... how can I answer lacking all facts above missing. why not buy a USB mouse and end the PS2 ERA. end it. go to goodwill store, buy used mouse USB for $1? next time tell what PC is there, it has name and model. then buy real mouse. USB, not PS2. my 2nd guess is you do not own any such mouse, in fact the numbers 143315-B21 , are not on the bottom of your mouse at all and posted to the wrong form. best is to post at HP, or at least post to your PCs name and model form mice come in many formos

1. 9pin serial (super relics) D-shell shape conn.
2. PS2 HP , or Compaq) green plug, year 2000 junk.
3. USB (sold in all stores, even walfart has em)
4. USB + wifi , wireless mice. (dead batteries?)

in each case the PC has model and so does the mouse. only that matters first, then why it fails 2nd. 143315-B21 (this mouse is 18 years old now) used back in the days of Compaq EN series Deskpro's 2000 year. Pentium III era. if that is your PC and is internet connected? are you? that old PC has 2 USB ports, and any USB mouse works there. and upgrade from nasty old PS2, green end plug mice. next time post to your PCs, name (HP) and model. like this, here is one example of posting the EN series PC http://www.fixya.com/support/t11372882-compaq_deskpro_en_case_opening

lost, wow a CRT that even glows at all , and you wonder why its dem the electron gun cathodes get weaker every day of its life. all CRTs do that, not one or even TVs using CRT the red gun always goes dim first so we crank it up in the OSD. if it fails on all PCs, the monitor is bad, a 5 min test. and bingo then if the monitor is known bad then what. the OSD screen ever seen that, and the front panel key marked MENU/? go there and play with brightness, and even the electron gun tuning, the page for that is RGB, Red Green blue. adjust them so white looks OK. but if all are dim, that is normal for old CRT, we only get like 3 folks a year stuck in 1990s... or older. the labor to fix it is 3 times a new LCD LED display. land fill time. like the other billion made, and scrapped

where is the LED< you never said. (exactly) monitor or PC, ? you posted a laptop to a forum called monitors which is it, a laptop , desktop or only a monitor.? toss coin, land LT. 2700 (legacy relic with square screen floppy and windows 98 first ones) take out the battery , the big one, it must run forever on AC power pack or its a hardware problem. (there can be 2 main batteries) 1 bottom and on the right rear, CD out, and battery is its place. yes, that is what they did then if you have it. I cant see yours. Next do the HP long reset. all batteries, out, now. (bottom big, right rear, out) power pack out. disconnected., push the power button from 10 to 30 seconds, this is the HP classic, long reset in every manual they make and on there service page, 1st thing. next is power pack, if still dead. the goal is getting the F10 key BIOS to work first. it must work at all times at power on power button on , hammer f10. and see bios if fact it told you to press F10 for 16 years now, every day. 2001 laptops have zero value. now. zero. upgrade to 2008 is better, put this one in he trash. go to goodwill store upgrade for $20? (they wont want yours, sorry, its too old) so do that. is bet but if maniacal. ? H3LL bent to spend $120 or more with a HDD bad, on a $1 PC, here goes. OS + HDD = $170 if the screen is dead now say so, say totally black screen what it did before it died, is not important unless the fan is dead is it? (all PC's ran ok before now) then ask for help, windows will shut done only if it is corrupted. (self) hardware has many cause of shut down, about 10 causes. one is the PC overheated from not cleaning it every year. the run down. BSOD (black) big battery out, AC pack only, got that? this PC has a place for 2 main batteries both out now. The PC has CMOS cOin cell, not one ever lasts 16 years. so that be like the first thing id replace (basic service this is) open bottom hatch cover to see it. 1: fan dead or all vent and to it blocked in lint as all are this old. 1b: fan dead not packed? see slide show of nasty LT here. http://www.pcdied.com/overheated.html 2: coin cell dead, above 2.9v ok, below never. remove it replace 3: power on hammer f10 the screen most show , "hit f10 to enter setup" if not bad screen or far worse (yes 3 billion transistors inside can fail, main board, or shorted modules inside up to 8) 4: now the flash light trick this old dog has CCFL back lamps. do this. http://www.pcdied.com/monitors.html#flashlighttest if that shows DATA, then the CCFL are bad. if no data now, the problem is more serious http://pcdied.com/black-screen.html#Laptop if it still is dead, we replace the power pack or remove all modules in the PC that can short killing power dead. any thing inside can short. 4 ways in fact, DC power, data, address or control buses. to find that we pull things, to find it. ask. im not teaching Fault isolation checks here. but that last link above has it, see key word stripping there (control+F) if all you wanted was to guess, say so, say no diagnosis guessing. for that I say it needs to be cleaned of a pound of dust inside and new coin cell and dump the 2 useless main batteries, if both there. left is power (both), right is battery failures. for the coin cell, (its hard to get to on this PC) read page 63 (pdf) here the service manual. is here, for free, do not pay scalpers for it. https://www.manualslib.com/download/273070/Hp-Compaq-2710p.html

i advise u to make total format to u hard disk drives and make it with out system

what CD, of the 100s? of types/formats/file classes, (what's there?) NO OS stated, XP the virus magnet. why post lacking this key fact, what Operating system.? or Linux, that is correct some came with Linux. SUSE its 7 years old, 2 times a few, but who counts years, well age matters.. yes, most users of PCs never leave confines of IE, still running IE5? well the list you made is near correct: 1: bad Disc or wrong disk. non stated. 2: bad drive. 3: bad driver. (cd/dvd HP driver) get it from HP 4: windows is corrupted. XP or w7 was shipped if windows. a/v clean or reload XP or do F11 HP recovery to cure this. First off, no CD stated, there are vast formats for CD the first that must work are: 1: CD-DA a store bought CD.. 2: any install disk, CD, with files on it , do yo see files"? 3: do you have the HP driver loaded for the CD drive? 4" was your, CD home made say burned CD-R ( recorded?) if XP is Service PACK 3 loaded? it must be. your PC came new with many CD/ DVD drive options even the LightScribe. the software is here. https://support.hp.com/us-en/product/compaq-presario-cq56-100-notebook-pc-series/4247498/model/4308236/drivers

use wired Ethernet, so it works. easy. wifi is far more complex. best is to own the router, you have. then login to it and set it up for wpa./wpa2 wep off. and a nice password for wifi so others cant hack it. in the hood. then use those credentials all all your toys. xbox, PCs and cell. that is the best way the access point is covered in you manual for the router there is AP button there, you push. the PC in question my guess is the drivers are no good. missing wrong, or corrupted. no PC full model stated. no OS stated no router stated. so answers will be weak to wrong,.

compaq presario SR5310F why down grade from dead, to super dead for 3 years now XP why do that? XP is a virus magnet. (hint 2, and glowing) your offical page is here. on real HP site, (we are not here) https://support.hp.com/us-en/product/Compaq-Presario-SR5300-Desktop-PC-series/3644727/model/3644732 click software click OS see what you get. ONLY VISTA support now I can make it work with 1/2days labor. but why do that? why ever use XP, USB only works 1/2 way with XP SP3 added and PLUG AND PLAY ON XP IS DEAD, making other 1/2 dead. for ever an ever. if pain is your game, here is how. drivers. ( my PCI sniffer lets me find (if possible at all) Any driver on earth. (unless reading every chip lid is fun....) http://www.pcdied.com/Drivers.html

this could be a few things wrong.you should never hit or knock the the harddrive for any reason. 1,could be dirt inside the fan if its not turning it will shut down so it does not over heat.if this is the reason just blow into were the fan is and try and free it up.or you may have to open it up to clean it. 2,make sure harddrive is pushed all the way into its fittings. if this does not work let me know.
