Thinkpad X Series Power Adapters (65W, 90W, etc) Lenovo Store Suggestion

Well, I decided to play pretend today on Lenovo's Thinkpad X Series laptop shopping site. My brother in law needs a new computer, so I look at all the options. Then it hits me, what is going on with the power supplies?
Here is the issue.
The 90W power adapter is cheaper than the 65W power adapter if you were to buy it as an accessory. Does that not seem backwards? In addition, when you buy a x201 for instance, you are stuck with the more expensive 65W power supply. You could add an additional 90W power supply to the order, but considering that the 90W power brick is not that much bigger (probably less than a half a square inch of the other) 65W power brick and it is cheaper and does more. Why bother with the 65W power supply anyways? In the store you can swap out the battery for a bigger one.
Why not have a downgrade option from the 65W power adapter to the 90W power adapter?
Just a thought.

The 90 watt adapter costs more to produce than the 65 watt, the price at the online store for accessory may change depending supply and demand. I am not sure why the 90 watt adapter dropped below that of 65 watt, in most instances the price is other way around.

No car power adapters work!

I have have tried 3 power adapters sold at the Apple store and none work with the PowerBook G4. The saleperson was very helpful, but said that they have seen this before! (Green light comes and then it slowly blinks yellow or just stays green.)
I asked what the solution was and they suggested that I used the Apple 110v adapter with an inverter. That is what I tried first and it didn't work. They said buy a more powerful inverter like they sell at Lowes. So I bought one and with the adapter pluged in all is fine. Plug the adapter into the Mac and the plug is green for a few seconds and turns yellow. When it turns yellow the inverter goes into overload, screams, and cuts off!
I called the store back and they suggested I order the latest kinsington adapter for cars from the Apple store online. Now it doesn't work either and kinsington says they have not found a way to charge this model in a car! Is that true?
PowerBook G4 (15-inch Aluminum) Mac OS X (10.3.9)

Actually I've had an iGo Juice for over a year now, and it works just fine in the car, in an airplane, and in a wall socket. (I use it on a 15" alumunimun PowerBook G4, machine model 5,2.) Radio Shack sells them, though I bought mine at Macconnection.
Hope that is helpful.

90w vs. 65w power adapters

We use the T61's and X61's with the port replicators for the T's and the Ultrabases for the X's. Is there any reason or need for the 90w power supplies? Please advse. Thank you.

Hello,
Welcome to the forums.
The difference between the 90W and 65W power adapters is quite simply the power output to the computer based on power consumption by the unit.
The T-series systems with dedicated video cards (NVidia or ATI) require the more powerful 90W power adapters - the 65W PAs will not provide sufficient power required by the dedicated video cards. Thus the 90W power adaper is the only choice for T-series systems with dedicated video cards.
The X-series, on the other hand, use an on-board graphics adapter without dedicated GPU and come with the 65W power supply simply because of the much lower power requirement. The X-series systems (whether docked in the X6 ultrabase or not), unlike the T-series sibblings, may use either the 90W or the 65W power adapters interchangeably.
Hope that helps

Does T61 with integrated graphic card come with 65W power adapters?

Hi everyone, i am about to buy T61 without the graphic card.
Plz help!, anyone knows it comes with which type of power adapters?? say 65W or 90W
Thank you

integrated graphic card model should come with 65 w power adapter... while those Nvidia one has 90 w power adapter..

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.

T61, WinXP SP2: Windows Power Options vs Thinkpad Power Manager (Standby/LID/etc)

My message is similar to this one:
http://forum.lenovo.com/lnv/board/message?board.id=T_Series_Thinkpads&message.id=4885
but show clear source of problem.
So I start...
I have [brand new ] T61 with XP SP2 Russian, installed from R&R disks from Lenovo through Vista Downgrade deal.
1. I set Windows Power Management (W.P.M.) to:
- standby when closing lid
- asks for password after wake up from Anabiosis (standby or hibernate).
2. Close lid -- notebook go to standby; open lid -- notebook wakes up. Fine.
3. Close lid -- nothing to do. Open lid - notebook runned a usual, no standby preparations ;(
4. Go to ThinkPad Power Manager (TP.P.M.) (useful left-click from Big Green Gauge in taskbar) -- all settings looks fine: options, checkboxes etc.
5. Open W.P.M. -- all settings messed up with random values:
- "no action" on closing lid
- "asks for password" checkbox not checked (this field varies through few tests).
6. Setting up needed options in W.P.M. again, repeat steps 2..3..4 -- nothing changes: W.P.M. saves options for first close lid action, then options messed up.
==================================
As I see, ThinkPad Power Manager builds on top of Windows Power Management and overwrites its options on some actions (power up/power down/close lid/etc) in unsmart way, turn off close lid action and bring *potentially security breach* by resetting option for asking password.
==================================
My other experience on close/open lid:
- Very old R43 at my work acts fine. TP.P.M. installed.
- HP 6820s works fine with standard W.P.M.
- HP nx7010 works fine with standard W.P.M.
Software versions:
- ThinkPad Power Management Driver: 1.44
- ThinkPad Power Manager: 1.30b
- All the hotfixes listed in similar topics installed by R&R disks
==================================
I... am... VERY... DISAPPOINTED! (c) Jean-Baptiste Emanuel Zorg
Is there a way to fix this TP Power Management suite behaviour?
Should I reinstall some of components?
Can I throw out TP Power Management toys and use WinXP native Power Management, ot there will be some ghosts like "yellow undrivered question marks" in Device Manager?
Thank you.

Message Edited by andyP on 04-22-2008 09:37 AM

I solved this trouble without Lenovo intervention:
- create clean WinXP Pro setup disk from R&R recovery diskset and install WinXP from it;
- install all the TP utilities & drivers manually, checking LID Close/LID open actions twice after each program;
- make full system backup (not R&R way) every 3..4 installed programs.
Entire process spend one week of my time.

Power adapters and worldwide compatibility - a lesson

The standard fare today in power adapters is such that the brick itself is compatible around the world. Indeed, the input power on a Lenovo AC adapter is rated from 100-240V and 50 or 60Hz - capable of operating on any power standard. The only catch is of course the wall plug in various countries. Again, most adapters have a removable adapter-to-wall power cord and if the manufacturer has a worldwide presence, you can likely order a country-specific power cord. Lenovo is such a company and you can find power cords for most geographies, like here. I'm preparing for a trip to New Zealand, my first out of the country, and wanted to be prepared to have my lifeline (aka ThinkPad) ready for the new locale. I looked up the power cord FRU (Field Replaceable Unit) number, called up IBM parts to verify availability, and placed the order. I was also delivering a new T61 to my mother-in-law and the U.S. power cord would be a burden down there. At $2.80 each plus a flat shipping fee, it was a no-brainer.
Australia/NZ Cord
As a side note, I ordered the adapters Monday night and they arrived Tuesday morning
I open the box to find a goofy-looking wall-plug (no offense... ) and what's this - a three-prong adapter-plug???
Australia/NZ plug
It looks a heckuva lot like the old T4x 16V power adapters and I figured I got the wrong FRU, dangit! After having gloated to Matt Kohut, our resident globetrotter, about my adapter-ordering-savvy, I mentioned in passing my situation. No sooner did my lips stop flapping did Matt whisk me away to a seemingly endless drawer in his desk, filled with dozens of black rectangles. Out of it came a seemingly normal looking 65W adapter.
Two very similar power adapters
Do you see a difference in the two adapters? I didn't at first either. Ah, there it is -
U.S. adapter vs ANZ adapter
It turns out that some countries still require an extra grounding wire in AC adapters and do the three-prong plug must be used. There I was thinking in my smugness that I could get away with a new power cord alone, not so!
I hope this helps anyone shopping for power adapters or cords soon. Thanks to Mr. Kohut I have a couple power adapters perfect for my mother-in-law's new T61, so she can compute around New Zealand without needing a silly plug adapter like us Yankees will use down there.
For reference, here are the part numbers in question:
2-prong 65W AC adapter: 92P1214
3-prong 65W AC adapter: 92P1153

X60 Tablet SXGA+ primary, Z61p fully loaded workhorse

They are different because the two notebooks use a different power system. Your R51 uses the old 16V adapters and the T60 uses the newer 20V versions. Starting with the Z60 series, it was decided to upgrade our power delivery capabilities to meet the ever-increasing power demands of mobile computing.

Alternative power adapters for the X220

As posted in other threads, there are problems using the "native" Lenovo power adapters with the X220:
- The 65W adapter does not supply enough power, which causes reduced performance.
- The 90W adapter is big and heavy.
- The Ultraslim 90W adapter causes erratic touchpad behaviour.
bender957 recommended the FSP NB L90 90W adapter that, according to his experience, does not suffer from any of the issues listed above.
Unfortunately, that post and others discussing that adapter were removed from the thread they were posted to as off topic, so I created this one to host the discussion.

The SNA 95 has arrived. It's about the same size as the new 90W Dell adapters, so maybe not as small as I was hoping. The Dell adapters struggle to put out 90W without getting dangerously hot though.
The output voltage is 19.5V with no load, so only 0.5V below the rated input voltage of the x220. I've yet to encounter a laptop that can't deal with ±1V. I just can't see anyway they could design a DC-DC converter so badly that it could only take 20V.

W540 power adapters

I had T500 before, and I thought that if I buy converter from round to square tip, I could use old adapters with w540. I was quite naive
I have seen a lot of topics about modding 90w power adapters, so w530 thinks that it's 135w adapter and it works ok. Did anybody try anything similar with w540 power adapter?
Solved!
Go to Solution.

Beats me, I had the same problem when I bought an Advanced Mini Dock for an i7 T520 dGPU model machine a couple of years back, it came standard with a 90W adapter. But I simply explained to our Lenovo partner here that this was for a 135W machine, and they supplied the correct adapter with it. Simples.
For the new xx40 Ultra Docks, the 135W and 170W models have the same FRU, which is 04W3947, so my suggestion would just to ask your local Lenovo partner to supply it with a suitable adapter for your machine. They use the same power input, unlike the barrel plugs for the earlier models.

Direction on safe power adapters for iPods from US to Travel in France

Hello, I searched other topics found the Apple power adapter plug for the ipod discussesd this topic (which I do already have), but it did not SPECIFICALLY say that it will convert from US (110v) to Euro - France (220) volt. All the instructions from available power adapters (non-Apple) specifically say 'not for use with stereo or musical equipment.'
Help ! Can I just plug in my Apple ipod power adapter INTO a standard 110v to 220v converter and not worry about problems? Do I need to look for a special voltage adapter that works between certain amps or voltage ranges?
Best Buy, Radio Shack, Travel Smith and Sharper Image were NO help.

Why did they have to ruin the Thinkpad T-series?

Hi all,
Just bought one of the very last T430 in a sellout, and this will most likely be my last Thinkpad, because Lenovo's design changes in the current T models are totally inacceptable for me. Actually, I even disliked the new keyboard layout on the Tx30 models, but I can still live with that.
I still do not understand why they had to ruin the iconic Thinkpad T-series. The obvious aim to make Thinkpads more Apple-like is totally ridiculous.
Consumers who want fashoniable laptops will still by from Apple. And most people who used to buy Thinkpad T models do not care about fashion. I even know many Thinkpad owners who loved there T models for being somewhat ugly.
Lenovo claims that there design changes were based on research, but the arguments they gave for the changes are mostly ridicuolous. For example, Lenovo says that the 7th row of the keyboard and the dedicated trackpoint buttons were removed in an attempt to make the design look cleaner and more regular. But really: What kind of silly argument is that? Ergonomy is certainly more important to the traditional Thinkpad owners than cleanliness or regularity of the design.
Apple's Jonathan Ives might claim that beautiful design and ergonomic design are the same, but if he does so, this guy is lying. There are many beautiful design that are highly unergonomic and there are many highly ergonomic designs that are rather ugly. Beauty and ergonomics do not have much to do with each other.
Apart from tactile feedback, the most important feature of an ergonomic keyboard is layout that sticks to the standard layout as much as possible. The reason is simple: This way, you do not have to adjust when you change between your laptop and a standard keyboard. Any unnecessary deviation from the standard layout is unergonomic for anyone who most also work with standard keyboard.
I spell it out for you: Apple keyboards are highly unergonomic due to their deviation from the standard layout. Only Apple fanboys who use Apple devices only will find these non-standard keyboard ergonomic.
In general, leaving away dedicated buttons just to make a device look cleaner or more regular, is totally unergonomic. Sacrificing key groupings for a cleaner look is also totally unergonomic. All these design decisions are wrong from an ergonomics point of view. Large touchpads that get into your way will typing are also unergonomic.
Lenovo should stop this and return to IBM's design principles. I want ugly Thinkpads again with an irregular, but ergonomic keyboard layout, dedicated trackpoint und touchpad buttons.
If Lenovo wants to be innovative, they should concentrate on the things that really need to be improved: Better displays, better battery life, less weight, etc. pp.

thinkpad t23 series lights and button symbols diagram.
I would like to get a diagram that lists the lights and the Thinkpad button along with its symbols. Like an arrow pointing to a light and telling me the X is functioning or not, along with the rest of speaker? symbols. Fn combos and their definitions would be good too.
I do not have the owner/user manual for the T23 2647TU but I imagine it would be printed in some form there?
Could anyone help me with this by directing to a web site or screen shot to the users manual that shows this information? I would appreciate it.
Thank You,

Hi Bob,
so here are some screen shots for you and others who may read in the future. This is a nice discovery for me also. Very useful, complete User's Guide for T23, XP version, which I actually installed on my W500 running Windows 7 Pro 64-bit. The possibilities are endless, not just for T23, but for other older models which possibly have a User's Manual archived online. It means I could simply cut and paste so many steps of information which for myself are so obvious and elementary, but will be invaluable to one of my young students learning basic computing skills. And the fact the User's Guide runs on my W500 means only the student needs to have a T23 (or whatever other machine in their hands), I don't need to have another T23 set up to access the manual.
Here are a few step-by-step guidelines which may can help you and others reading in the future. Don't mind me putting so many details. As a teacher I like to explain things in such a way that even if one my 3rd grade students were to read this post they could follow the steps. Some people have never really used a laptop at all before and will be glad for simple, detailed steps:
How to install T23 Access User's Guide on a Windows 7 machine (should be nearly identical procedure for XP or Vista):
(1) As mentioned before just go to the Drivers and software - ThinkPad T23 download page: http://support.lenovo.com/en_US/research/hints-or-tips/detail.page?&DocID=HT072383. There, under the "Software and utility" category you will find: Access online User's Guide for Windows - ThinkPad T23: http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS001263. Download the file and transfer it to your T23 using a USB flash drive. (In my case I downloaded it directly onto my W500)
(2) Double-click to run the downloaded file. It will extract setup files to C:\DRIVERS\ATP_PKG by default.
(3) Click the START button ---> Computer----> Drivers ---> and double click to open the "ATP_PKG" folder. Double-click to run the "SETUP" application file.
(4) After installation, you can navigate to Start Menu ---> All programs ----> Thinkpad ---> Thinkpad information, and RIGHT-CLICK "Access Thinkpad". You can then choose to "Pin to taskbar" and/or "Send to desktop (create shortcut)" which will create an ACCESS THINKPAD logo right on your desktop with the cool old IBM logo which you can see in one of the pictures.
I have included a few snapshots showing my W500 with T23 User's Guide installed: Main welcome screen with cute T23 animation (hence the blur); Main menu- notice even a link to reach IBM for warranty information (if anyone still has a warranty on their T23, joking of course); And "everyday use" menu which includes status light indicators and FN-key assignments you asked about. So you see how useful these old "User manuals" can be, because if anyone comes on the Forum we can just cut and paste information from the User's Manual. Some people (especially young people ) need that level of clarity and simplicity. And it's just a small file, 21.8 MB downloaded onto my W500.
Below I <CUT> and <PASTED> a section from the User's Guide. Here are the Function keys you asked about (the pictures which didn't come out in cutting and pasting got replaced below by " " and are just little asterisk symbols and a small diagram showing where FN key and Home/End keys are). Of course this can be remedied by taking screen shots instead:
Function keys
The Fn key function enables you to change operational features instantly. To use this function, press and hold the Fn key (1); then press a function key (2)--F1 to F12, PgUp, Home, or End.
The following shows the functions of the Fn key with other keys:
Power conservation or battery power
Fn + F3: Turn off the computer display, leaving the screen blank. To turn the computer display on again, press any key or press the TrackPoint(R) pointer. Also the computer display is turned on if the ac adapter is attached to or detached from the computer.
Fn + F4: Put your computer in standby mode. To return to normal operation, press the Fn key independently, without pressing a function key.
Notes:
This mode is called suspend mode in Windows(R) 95 and Windows NT(R).
In Windows 2000 and Windows XP, this combination of buttons functions as a sleep button. You can change the settings so that pressing it puts the computer into hibernation mode or even shut the computer down.
Fn + F12: Put your computer into hibernation mode. To return to normal operation, press the power button for less than four seconds.
Note: To use Fn+F12 for hibernation in Windows 2000 and Windows XP, you must have IBM PM device driver installed on your computer.
For information on the power management function, refer to Extending battery life.
Other functions
Fn + F7: Display output on the computer display, an attached external monitor, or both. Pressing this combination causes the display to go from the computer display to the external monitor, then to both together, and then to the computer display again:
External monitor (CRT display)
Computer display and external monitor (LCD + CRT display)
Computer display (LCD)
Note: This function is not supported when different desktop images are displayed on the computer display and the external monitor, or in certain cases in which the same desktop images are displayed on both screens, but the refresh rates of the screens are controlled separately by the system.
Fn + F8: Switch the computer screen size between expanded and normal mode if your computer display image is smaller than the physical display.
Note: This function is not supported in Windows 2000 and Windows XP.
Fn + PgUp: Turn the ThinkLight on or off.
Note: The status of the ThinkLight, on or off, is shown on the screen for a few seconds when you press Fn + PgUp.
Fn + Home: The computer display becomes brighter.
Fn + End: The computer display becomes less bright.
Note for the Fn key lock function
The following setup gives you the same effect as when you press and hold the Fn key and then press a function key.
Start the ThinkPad(R) Configuration Program. Click the Accessibility button, and click Enable for Fn key lock. You can also set up by typing PS2 FNS E at the command prompt.
When the Fn key is not enabled, you need to hold it down while pressing a function key. When it is enabled, you can use the function keys more easily:
Press the Fn key once. The next time you press it, you can release it and then press a function key, to get the same effect as if you had held the Fn key down while pressing the function key.
Press the Fn key twice. Then, for the rest of your session, you can press any function key without pressing the Fn key again.
Have a great day. (I do not work for Lenovo)

Compatible power adapters?

My daughter is living on a remote Pacific island with an old Titanium PowerBook (400 mhz) that she says is suddenly not getting power from its power cord. She is assuming the problem is the adapter, which is the yoyo-type.
I have here in the US two power adapters from later models of TiBook, both of them the white brick variety; one is 45W and one 65W.
I seem to remember trying to plug one of these into her PowerBook before she went overseas and not being able to, but I may not be remembering right. I have just mailed my daughter both of my adapters, but meanwhile I am hoping someone can tell me whether they will fit (and she'd use whichever one matches the wattage of her present one).
If she finds it doesn't fit, a lot of time will have passed before I am faced with buying a yoyo type and mailing it to her. But though I've found one on PowerbookMedic.com that seemed to say it went with a Titanium PowerBook, that information on the page was ambiguous, and when I phoned the company, a guy said I could use any Tibook plug with any Tibook laptop.

Hi, Paul. Either of the adapters you've sent to your daughter will work with her 400MHz Powerbook, which originally came with a 45W adapter. All Powerbook and iBook G4s use the same size plug, but the later, more powerful models need a 65W adapter for full, reliable, as-designed operation. Your daughter's machine doesn't, but neither will a 65W adapter do it any harm.
Let's hope it's her yoyo adapter that's at fault, not something in the Powerbook. And I also hope life on a remote Pacific island is as idyllic as it sounds from here in rain-drenched, muggy New England.

Do Apple MagSafe 2 power adapters break easily?

I was about to order a Magsafe 2 power adapter for my rMBP so I could keep one at home and one at work. But there are hundreds of reviews at store.apple.com saying they break easily, the wires fray, etc. but I've seen very few complaints about them on this or other user forums, and none of the five I've owned for various MacBooks since 2010 have ever broke.
Are Macbook power adapters really so unreliable and prone to breaking? Or is it possible that the reviews at Store.apple.com are so dominated by trolls as to be unreliable?

People don't often write reviews about things as mundane as power adapters unless they have something to complain about. I have one that's only recently started to fray. It's four years old. I have many others as old, or older, and they're fine. Treat them carefully and they ought to last the life of your Mac.

2 Power adapters...one glows amber to charge the other stays green??

Hello,
I have 2 power adapters for my ibook, the one that came with it originally & one I bought as an extra. They are both 45W apple ones. I have had problems with my ibook powering up & after replacing the dc-in board to no avail I have been told it's the logic board that needs replacing.
I have just got a replacement logic board which I am yet to fit. As it stands at the moment I have replaced the dc-in board but still won't charge the battery?
Also when I use the adapter that came with my ibook the light on the adapter glows green. When I plug the extra adapter in it glows amber but doesnt charge the battery?
I am just confused as to why one adapter glows green & the other glows amber with the same battery in?
I am also concerned to know if it would have been possible for the replacement adapter to have caused the logic board failure in the first place? As I am replacing the logic board soon I don't want the same mistake to happen again!
Anyone help??

All-right Master Meister, one last throw of the dice for me...
Do you have a friend or relative who knows how to use a multi-meter? If so, get them to check the voltage + current flow from the adapters when connected to the mains (iBook unattached).
Please do not try this yourself if you are unfamiliar with multi-meters; you could electrocute yourself or irreparably damage your equipment.
If you are reasonably competent with basic electronics, hook up a 12V car battery to one side of the charger and a 3V torch (with batteries removed) to the other side. If the bulb lights, this will tell you if the adapter is working.
I mean no disrespect: this is a potentially dangerous experiment and if you don't feel you are up to it, then don't try.
Instead, take the adapters to your local electronics store and pay them to check them for you.
