90W Ultraslim AC/DC Adapter

Has anyone used this adapter with their W530?
http://shop.lenovo.com/SEUILibrary/controller/e/web/LenovoPortal/en_US/catalog.workflow:item.detail?...
I'm looking to get a second adapter that I can leave in my bag for travel puproses and thought something slim like this would work great. I noticed that it is only 90W though. Will this limit the computer in its use while charged to this adapter? Such as, will the CPU automatically throttle down or will it only run integrated graphics as opposed to discrete graphics?
Silly questions maybe, but I just want to make sure it'll be usable before I make the purchase.
Thanks,

same performance and stability as with the 170W adapter. (I don't use a dock)
I have been using the 135W adapter as a travel adapter for many months.
(According to another thread, the 90W adapter also works if you do a minor modification of the power adapter plug, which then tricks the W520 into thinking it is dealing with a 135W adapter)

  • 90W Ultraslim AC/DC Combo Adapter Making Clicking Noise

    Hi.  I have a brand new T420s with the 90W Ultraslim AC/DC combo adapter.  When I have it plugged into the system it makes a clicking noise.  When I unplug it from the T420s it has a very faint, high pitched humming noise.  Is this normal?
    Thanks!

    no it is not normal. Call warranty for replacement.

  • Spare tips for Lenovo 90W AC/DC Combo Adapter

    Just got the Combo Adapter, and wanted to order a spare tip to charge my Motorola cell phone with it. Dumb question - will the spare tip plug into the power cord of the adapter, or do you have to use the dual-charge cable for the tip to work? I rarely charge two items at once, and would prefer to not travel with an extra cord.

    yes it works with the T510.

  • Smart Pin Dongle AC Adapter 90W KG298AA

    Hi,
    I have an HP labtop of model: dev6 2170ee
    I want to get an AC adapter, and I found that the chargere :
    Smart Pin Dongle AC Adapter 90W KG298AA
    is compatible with the serice:
    dv6-2100 Entertainment Notebook PC series
    However, my original adapter 10 120w rather that 90w, so is this adapter is really compatible with my laptop??
    Please help me.
    Thanks so much in advance,
    Best regards,
    Aya.
    This question was solved.
    View Solution.

    According to page 1-3 under the ports category of the Maintenance and Service guide, the notebook should be using a 90W adapter.  Not certain why it came with a 120W adapter. 
    According to the compatibility chart found here, the dv6 2170ee (in the dv6-2000 series category) is not compatible with a 120W adapter and lists 90W as the highest capacity. 
    Based on the available information, 90W should be the correct one. 
    If you want to order direct from HP, this should be a compatible adapter.  You can also use it to compare the replacement adapter you are looking at to be sure it is compatible.  I suspect this is the one you are looking at based on the provided part number.

  • W530 Power Adapters, 90W vs 135W Vs 170W

    I Just got my W530 3720QM K2000m and i find it ridiculous that it cant use the 90W Adapter when idle and uses the battery. I Read threads of similar things with the W520, as well as some on the W510, and it appears that this used to work on the W510, 90W power adapter delivered the system in working condition with reduced performance. Now, i use my laptop as both a worstation and an entertainment laptop. if i were to go on a flight or be in a car, i sure wont be doing intensive VMware or 3d stuff, so 90W would be more than sufficient to drive the laptop as well as charge the laptop. i even have a Killawatt meter, i plugged in the 170W Adapter into it, and then ran my laptop while having the battery charged. the max power consumption that it pulled was 70W At the wall, surfing the web in optimus mode. Why cant we have a power saver mode to allow usage of the 90W adapter? or at least have the Choice between "battery only" - reduced performance anyways and "reduced performance AC/only"? At the very least it would avoid draining the battery for absolutely no good reason. My system idles at under 30watts anyways and that would leave 60W to do anything else, for example charging the battery at 40W - to give the total of 70W at the wall, from the 170W Brick. i Wish to see a revised bios to correct this or at least allow this. i dont believe its impossible or too complex to code. it was done on the W510, i dont see why it cant be done on newer, improved, smarter, more power controlled, 22nm ivy bridge based systems. and yes, if i wanted to use the full power of my machine i would have the 170W adapter, however, i currently own a T60, T61, T400 and now just added a W530, so i already have two docks + 4 90W adapters, + a 90W AC/DC Travel adapter. having to purchase another 170W adapter is kinda ridiculous, not to mention that its not compatible with any of my three other machines due to the fact that it is keyed. Please make a bios revision to address this issue. Thanks.

    given my tests were done on a W530, i shall post my results here.
    Bottom line: Lenovo power manager has no freaking clue as to how much power the system actually uses when its plugged into the wall. it cant even do basic arithmetic.
    In any case, these are my findings. on the W530, with a i7 3720 QM, 32gb of 1600mhz ram, K2000m, these are my results on power consumption.
    These tests were done to see if there was a logical explanation for not allowing the use of a 90W adapter at all on such a machine. bottom line is, if throtled, there is no reason not to. limiting the use to intel gpu only and not allowing turbo boost, effectively eliminates ANY possibility of using more than 90W when not charging the battery. The proof: The last two lines of this table. 60W Max power consumption at the wall under OCCT PSU Test when the cpu is limited to 2.6ghz, and the battery is removed/not charging. PSU Test stresses both cpu and gpu simultaneously.
    The first battery of tests were to find out what tests should and shouldnt be performed, and what numbers were accurate. it was clear that power manager had no idea how to do basic math and later tests did not include it's random numbers. it only properly aproximates power consumption when on battery, not when on AC.
    It was also concluded that using OCCT:CPU Resulted in the same power draw as CPU: Linpack, and thus OCCT CPU Was used to expedite number crunching.

  • Hp smart ac adapter (power supply)

    what is the difference between the ac smart adapter 90w-19.5v and 65w-19.5v?
    if i use 65w-19.5v ac adapter instead of  90w-19.5v ac adapter , will it create any harm to my laptop or laptop battery..?

    IF your notebook was delivered with the 90Watt unit and you switch to a 65 watt unit, you may find that you start seeing warnings popup onscreen that caution you that the power supply is no providing enough charging capacity.
    It won't hurt the notebook at all, but it is not good for the main battery.
    The warning means that the battery is likely to not be fully charged by the 65 Watt power adapter.  If your battery does not get fully charged, its service life may not be as long as expected. The main battery is warranteed to one year. With most notebooks, owners get two or more  years of use from a battery. That is only if the battery was charged properly.

  • Charging using cigarette lighter?

    I have a solar charging  unit that has a cigarette lighter jack  that puts out 6v, 12v, or 7.2v DC. Is it possible to charge my x201 using such a cigarette lighter configuration ? What would be the cheapest way to do this?

    Hello,
    Lenovo's new 90W Ultraslim AC/DC Combo Adapter comes with a 12VDC automobile cigarette lighter power adapter plug.
    You might want to consider one of these—while it probably will not be the least expensive, it will probably weigh less and be more efficient than carrying a DC-to-AC inverter around, since it takes the place of your AC adapter, as well.

  • Replacing my dv6-1260se power supply, need help.

    I am in need of a new power supply for my laptop and was wondering which one would be the best.  i believe my options are the 90w smart ac power adapter and the slim power adapter.  any suggestions?

    So what's the issue you're having?
    I have never heard that rumor, a volt is a volt, an watt is a watt.

  • Battery charges but ac power not recognized Presario CQ61

    Hi everyone.  I have a Compaq Presario CQ61.  A couple days ago after doing the windows 7 system update (don't know if this is really related or not) my computer stopped recognizing the AC adapter.  What I mean is the battery still charges all the way to 100%, but the OS never recognizes the computer as being on AC power, only battery.  This is annoying and makes things like updates, installs, and gaming extremely difficult and/or impossible.  I tried unistalling the Device in device manager and re-installing it.  I can't reflash BIOS because the software requires I be on AC Power.  I've even down a sytem restore and got nothing.  Please help if you can...I really don't want to factory reset.  My computer is not under warranty by the way.
    Thanks in advance

    My question regarding the icon was actually related to how it appeared in normal mode rather than safe mode.  I apologize for not making that clearer.  Safe mode was just a straight verification of the presence of the issue without doing anything else.  
    According to this document, which may not necessarily be updated, there are seven adapters that should work with this notebook.
    HP 90W Smart Pin Dongle AC Adapter
    HP 90W Smart AC Adapter
    HP 90W Universal Power Adapter with USB
    HP 90W Slim Adapter - 
    HP 90W Notebook PC Auto/Truck Adapter
    HP 90W Smart Combo AC Adapter
    HP Slim Travel AC Adapter
    Most of these are 90W adapters.  The only one that is supposedly rated at 65W is the last one and it's a special use adapter.  I'm not certain why the replacements for this unit are marked as 90W and the one it originally came with is a 65W, but most HP notebooks do use 90W adapters and the symptoms do align with an adapter that is rated to too low for this system.
    However, you could perform a system restore followed by  a full system recovery (if the restore didn't work) to rule out any software (e.g. drivers) issues.  By chance, do you happen to have access to a 90W adapter to test with?

  • Dv9000 AC Adapter 65w - 90w compatibility 453198-001 453199-001

    I have the Pavilion dv9000 - part number: KN866UA#ABA - model: dv9815nr.  It came with a 65w AC adapter.
    I came across the 90w adapter and have been told it is compatible with my laptop.  Are these AC adapters truly compatible/interchangeable?
    The only issue I have found is that the 90w is for systems with dual lamp display assemblies while the 65w is for single lamp.
    Can I use the 90w AC adapter on my laptop that originally came with a 65w adapter?

    When it comes to the ac adapter there are two specifications you need to focus on:
    1. Voltage (output)
    2. Amperage (output)
    I'll use the example of an Asus notebook I have in the shop right now.  It actually shipped with a 65W ac adapter, as it only had integrated graphics.  However, there was an alternate model that shipped with a discrete adapter (nVidia 6600go).  That model required a 90W adapter.
    On both models, the AC adapters are 19V output models.  Where they differ, however, is in the maximum output amperage.
    The 65W max amps out is 3.42A, and the 90W is 4.74A.
    Keep in mind that WATTAGE = VOLTS * AMPS...
    The other thing to understand is that the ac adapter is not always putting out 65W or 90W.  The long and short of it is that the notebook (or PC) draws a certain amount of amperage per component usage.  On desktops, it tends to be a bit more constant as notebooks now have active power management, which means they adjust their performance and power usage specs according to usage (though, desktops are starting to have active power management more and more also.)
    So the bottom line is that, as long as the AC adapter is compatible with the unit, a 65W requiring notebook can use a 90W adapter, because the voltage is constant and its total amperage usage will never reach the full capability of the adapter.
    YOU CANNOT USE A LOWER WATTAGE ADAPTER ON A HIGHER WATTAGE-REQUIRING NOTEBOOK, HOWEVER!!!!  If a system requires a 90W, it's most likely because its maximum amperage draw is significantly higher than what a 65W can supply.
    Hope this helped!

  • Wire that goes from 90W Power Adapter a1097 to apple cinema hd display

    We lost the wire that goes from the 90W Power Adapter a1097 to the Apple Cinema HD Display. Where could I purchase another one and what is the name of this wire?

    The wire that comes from the power supply is tethered, meaning non-detachable, so I don't see how it can be lost. Or maybe I am misunderstanding. Is it the AC cord that is missing, e.g. the one that goes into the wall? That should be a normal IEC 320 C13, which is commonly available. You don't need the Apple one.

  • Can I use 90w power adapter interchangeably with my 65w computer?

    I have two Thinkpads:
    1) T400 that has a 90w 20v power adapater
    2) T430S that has a 65w 20v power adapter
    Can I use the chargers interchangeably on the computers?  Are there any concerns, side effects?  My assumption is that using the 65w on the T400 will take longer to charge the battery.  More importantly, I would like to know if there will be any damage if I use the 90w charger on the T430S.
    Thanks.
    Solved!
    Go to Solution.

    You can interchange them without harming either ThinkPad. Note that there will be limitations with a 65W adapter:
    1. It will take longer to recharge the battery.
    2. It may not be powerful enough to power/recharge certain configurations, e.g. with i7 processors and/or discrete graphics processors.
    3. It may not be powerful enough to power/recharge certain types of usage, e.g. when watching a DVD while at the same time running HDD intensive applications.
    4. Certain features, e.g. RapidCharge on the T430s, won't work.
