    So my original Delta ADP-230EB T 7.4*5 230w PSU finally died today, confirmed after removing the battery and trying to power the laptop with it turning off (LED Light Still on) once it loaded up the GPU Drivers in Windows!.

    I have been looking around and it would seem Delta ADP-230EB T 7.4*5 PSU's are gold dust, @1GreyGhost1 has helped me find a Zbook HSTNN-LA12 Omen 230w PSU with the same Output Voltage and Amps (19.5v / 11.8a) it also has the right size barrel connector 7.4*5 (Just not a 45c Angle connector).

    So looking for ideal replacements as a backup plan.

    Original PSU Specs:

    Code:
    Input:100-240V~3.2A 50-60Hz
    Adapter Output Voltage: 19.5V
    Adapter Output Current: 11.8A
    Adapter Plug Size: 7.4x5.0mm
    Pin: 2 Pin

    try cmos reset

    30s power button when run
    ,.,I've already got it a few times "orange indicator" - battery low voltage + ac -but not working recharge
    after reset -my nb normal works

    delta or chicony is MSI oem
    ,.,.delta 230 or 330 -no problem

    ,..some PSU is positible monitor on HWINFO
    gpu tab .,,.ppinput - PSU


    ,..,or "multi-meter 20V measurement"
    try find info works or not ?? ""inside is + ,..,is out - ,.,.but it doesn't matter "you see 19.38 or -19.38V"

    "4pin "2x up is +" down holes is -"

    edit ,.,when use any auto-update app
    remove acpi battery / second battery drivers in windows + reboot
    use only oem windows build drivers

    @zipperi Thanks for the link have had a look will have to see what import and customs will be from USA to UK.

    @NeXt3R I have CMOS reset and even EC Flashed and reset it still does it (First thing i tried).

    The fact is that the PSU is 5 Years old (Its the Original), thats been running 24/7 almost the entire time above 160w+, the PSU used to get very warm now it no longer does so.
    I used a KillerWat meter and found that if i placed loads Whilst in dGPU mode it would get to 150w or even 180w before bombing down to 80w and going into battery mode.

    Currently i have tested so far that if i can keep the PSU below 100w using the iGPU right now i can safely use the laptop without it bouncing from AC to Battery, also PSU isn't getting warm like it used to but at least i have access to all my files and i don't have to put up with the crappy 1280x720 screen on the Thinkpad R61e (Once you've used 120hz 60hz seems a slideshow).

    As far as the barrel its the 2 Pin one and not 4 pin one.

    The Zbook HSTNN-LA12 Omen 230w PSU has been ordered and should be here on Thursday hopefully the polarity is correct as its the same spec (Looks like the same PSU i have just without the 45 degree angled jack).

    I know the dGPU is sound and good i checked when i did maintance last week the VRM's looked fine and if i down clock the target Power from 100% in Afterburner (78w) down to 50% the issue stops and whilst i increase the target power to 125% 90-100w it does it even more often.

    So to me its the PSU (Checked the jack and it still looks solidly connected and the joints looks good during maintance)

    need only same Voltage and connector
    ideal DELTA ,.,.is OEM

    when use 330w get same limits ,.,.but not all time run on MAX "PSU overheat"

    my 230w oem - when run all time on max ,..,sometimes get random drops
    330W for my OC ,.,.still gets all time same stability "long usage 230w"

    edit
    the only problem is what is possible EC or something ,.,.verifies the connected power supply
    ,, but I think only voltage is verifies

    recharge on more amperes ?? still locked - 30W recharge,.same results for 11.8A or 16.9A
    ,.,.minimal battery wears "my gt75 7re ,.,.230W oem"

    edit .,,translation fix .,,mind error :D

    @NeXt3R so only the output voltage matters?

    So basically i could technically use an Alienware X51 /M17x PSU @ 330w

    for this old NB
    need spec 19.5V // correct connector + inside/ - out
    when check actual PSU -- marks or images "but not exist conversely ??"

    ,.,.AMPERES -19.5V x 11.8A -230w ,.19.5V x 16.9A - 330w
    and diffident not exist ,.,.NB still draw maximum what is in EC FW or BIOS setup

    only battery recharge speed is problem ,.,.but on my GT75 this look identical ,..,same EC limit 30W recharge lock
    it's been about a year ,.,.i still get same wear level // others info

    delta 330w

    edit
    only matter on EC ,.,.when verifies PSU ID
    when this exist

    but as i wrote i think it only controls the voltage ,.,or get message on boot
    voltage is same -- OK ,.,possible try this AC

    full info "same yours alien ?"
    https://www.newegg.com/p/2WG-00MC-000M8
    and this stronger ,.,.input 3.2A on old ,.,.this DELL is 4.4A
    out is same for 330w // MSI 4 pin is 3.5A

    dell look more stable in load
    ideal find 330w your connector + marks "info"

    edit
    ///// MSI 330w ,.,same pin type "input 4.4A for this connector type" liteon - delta
    https://www.chinahao.com/product/554372895857/

    look same
