    1. Version 0.5
    2. LYBMNK: Intro
      1. LYB8NQ:   http://support.dell.com/support/DPP/Index.aspx?s=dhs for says unit comes with:
      2. “1 WK890 ADAPTER…, ALTERNATING CURRENT…, 90W, DELTA – AC ADAPT…, 3P, WORLD WIDE…, M09″
        1. LYBVYV: Supply says output is “19.5V, 4.62A, center-is-plus”
        2. LYBW6X: GS(WK890 tip mm) says tip is 7.4mm*5.0mm
        3. LYBMGW: The power input plug on this supply is straight, sticking out of the laptop about 2 inches, which caused great stress when it was bumped, and eventually the male/external part of the plug failed.
      3. LYB8IP:   the power connector I fixed for it now lacks the LED and this small change seems significant enough that the BIOS complains its an invalid adapter and (probably from the BIOS) the battery won’t charge.
        1. LYFTJU: After BIOS startup, get message ”
          WARNING: The AC adapter type cannot be determined.\This will prevent optional system performance.\Please check AC adapter connect properly, remove \AC adapter and plug-in it again, thanks.
          Press <F1> to continue……\Press <F2> 2 times to enter SETUP\Press <F12> and Any Key to enter Boot Menu
      4. LYBMM3: Now I need to put the laptop to use again, so fixing this is urgent.
    3. LYD8VD:   What is the situation?
      1. LYD8ZP:   Why (the battery won’t charge)?
        1. LYD8ZY:  Until (KEP2DU ~8hrs ago), I thought it was just the motherboard being a bit picky about the voltage -NO (see next)
        2. LYD90O:  motherboard expects to receive a digital signal from power supply letting it know it’s the right type!
          1. KEP2DU:  Google Search “dell studio special power supply charge battery” find 3 says this is a signal pin not connecting.
          2. LYD8GV:   Google Search “Dell power adapter type cannot be determined BIOS” find 1 item ~3 says the power supply is transmitting a binary (1-wire) code thru the signal pin to identify itself.
      2. LYD961:   Possible options:
        1. LYD9DE:   Turn off this feature, specifically Set the computer so it accepts all power supplies for charging the battery even w/o this signal
          1. LYD9FF:   Via present BIOS A08: NO
            1. LYD9GC:   Has no option to turn off this insurance, just to disable the alert of the problem (which does only that)
          2. LYD9HN:  Via updating to latest BIOS? TBA
            1. LYD9KR:   http://www.dell.com/support/drivers/us/en/19  list ”

              A09

        2. LYD96S:   Get a power supply which sends this signal.
          1. LYD97Z:   CON: likely not have the L-shaped plug so in the situation again.
          2. LYD9E4:   CON: Likely not to be universal
          3. LYD990:   PRO: obtainable by warranttee if still in effect.

    4. LYB8JW:   Which replacement?
      1. LYD9RP:   PREFACE: these adapters currently have not been checked for LYD8ZY.
      2. LYB8P9:   ebay search “WK890” finds several but they all seem to have the straight plug which caused the problem in the first place.
      3. LYB97X:  ebay search “(WK890,Dell 1737) (AC,power) (adapter,charger)” doesn’t seem any better.
      4. LYB9F0:   ebay search “Dell 1737 adapter” doesn’t seem any better
      5. LYBNAD: Look for universal power supplies:
        1. LYBNBL: This has the advantage that it can also power other laptops I may need to power as Asus EE PC 1000P.
          1. LYBWH5: Here is a good one which is NOT universal.
          2. LYBX4X: Google Search “Asus 1000P adapter tip mm” finds “Voltage:19V Output Current:3A Power:36w Tip:4.8mm * 1.7mm -appears wrong.
          3. KEP2DU:  Google Search “Asus 1005pe power adapter mm” finds here  saying “The adapter replaces ADP-40PH AB with 2.5mm x 0.7mm SMALL TIP. “
          4. LYCFX9: Center is “+” from looking at one
        2. LYBNSI: Found 1 but not clear if it supports Dell
        3. LYBNSX: Did eBay search “universal adapter Dell Asus”:
          1. LYBNUJ: Find RF-BPRAC3

            .

            1. LYBWEB: For Dell: will need to do “Additional 7.4mm x 5.0mm tip for Dell Inspiron / Latitude series \ please contact seller to add it.” -hopefully that is enough even though this is Dell Studio.
            2. LYBX7O: For Asus, looks like “Tip 1 Ø4.75mm x Ø1.7mm” will work.
            3. LYBXBS: Right-angle plugs? Not clear from ad but from image looks unlikely.
        4. LYBNWV: Look for Rocketfish Universal laptop power adapters on RocketFish laptop accessories.
          1. LYBOUO: Use “laptop & netbook tip Wizard” to find matching tips:
            1. LYBOSCRocketfish tip for Dell Studio 1737.
            2. LYBP78: About 30 Asus are listed but not any # close to “1000PE”. Not available?
          2. LYBPDA: Use netbook & tablet tip wizard
            1. LYBPI9: find Rocketfish tip for Asus 1005PEB-RB

            6. Questions or Comments:
              LYBSAJ=I need an AC adapter to power both:
              * a Dell Studio( laptop) 1737 (so say using your tip http://configurator.battery-biz.com/productDetails.aspx?part=MT23&mfg=79&model=3927992&s=09f57ec1-f1cb-4813-b41f-d00a1fce5652 ) and
              * a Asus( Netbook) 1005PEB (so say via your tip http://configurator.battery-biz.com/productDetails.aspx?part=N5&mfg=443&model=3950251&s=241de0ce-3491-4073-8ed8-3f9c3bb92a31 )
              (1 at a time).(1) Do you sell a SINGLE power adapter with enough wattage, as say
              * http://www.rocketfishproducts.com/products/computer-accessories/RF-BSLAC.html or
              * http://www.rocketfishproducts.com/products/computer-accessories/RF-BPRAC4.html power ) which can do it? –I want the same power adapter to be usable for either.
              -It looks like NO (as it looks like each tip has a different connector-to-power-cable, and there are different tip wizards (though they’re both named “tip wizard”); however I wanted to ask to be sure plus suggestion.
              (2) And if this isn’t possible now, why not? And
              (3) When might you sell this? Thanks in advance-Your response I will also publish on //http://1.JotHere.com/776#LYBNAD to benefit others, too.

              Aside: a small but troublesome bug in this your webform I’m completing, http://www.rocketfishproducts.com/contact-us.html : it thankfully gives the ability to enlarge the “Questions or Comments” section but at least in latest Chrome browser it doesn’t work entirely right as the field is enlarged but not the gray box around it.

          2. LYCEJF: “M4: 4.8×1.7mm Replace HP Compaq 18.5V Max. 90W Laptop AC & DC Adapters” looks like it would work with Asus 1000P (if center is “+” which usually is the case)
          3. LYCFZM: “M9: 7.4×5.0mm Replace Dell 19.5V Max. 90W Laptop AC & DC Adapters” would work for Dell Studio 1737.
          4. LYCG1K: Having the 12V option would be an advantage as one wouldn’t have to carry a separate DC-to-AC inverter.
          5. LYCG3D: Having the USB could easily be handy especially when laptop is off.
          6. LYCGHR: Tiny pro: LED looks cool.

          7. LYCKTA:  Says it’s compatible with many HP-Compaq laptops and looking at an HP-Compaq laptop power adapter it has ” 18.5 Volts, 65 Watt, 3.5 Amps, 4.8mm x 1.7mm Connector ” same dimensions plug as Asus 1000P so should be fine.
