Potentially bad? P151HM1 + EBAY 180Watt PSU

Hey guys,

Just a quick question...

I own a clevo P151HM1 and it was shipped with a 120 watt PSU (as normal) but I went out and purchased a "replacement" power adapter for a P150HM (i believe the P151HM1 shares the same motherboard) from ebay which was a 180watt power supply...

Now at first i assumed it was faulty and sent it back under warranty, and a replacement had just arrived today, and its still doing the same "issue" but i dont know if its anything bad.

Ok so here goes.

When there is no power plugged in, the trackpad does not skip or jitter or basically flip out at all when moved fast (if i touch corner to corner of the trackpad diagnally)

When there is power plugged in from the 120watt power supply (factory) the computer is fine when using the trackpad with the above actions.

Now...when the power is plugged in via the replacement 180watt power supply, the trackpad gets jittery and stumbles in the direction i point it to, but only when i move it fast (diagnally corner to corner repeatedly) BUT it works fine when using a USB mouse.

Not that i would use the trackpad in FPS games, but if im browsing around my computer pretty fast constantly opening and closing things using the trackpad its a bother...

Everything else works fine as far as i can tell...would anyone know if this is causing a short or anything potentially bad? I tested the 180watt power supply in my girlfriends Acer laptop (old 7738G which only requires 90watt) and it has no issues what so ever...

Any comments would be appriciated

Thanks

 

I am using a 180w PSU for my P151HM1, but I can say I have never used the trackpad. I have noticed zero issues otherwise though - well other then size

I also have a 180w PSU directly from Clevo, but doubt that matters.

 

I can't imagine why just the trackpad would be affected by a faulty power supply. Is that the only thing you're noticing? A 180w should work just fine on the P151HM1 though. If you're really worried, get out a multimeter and check the output on that power supply to be sure it's really supplying the voltage/amperage it's rated for.

Cheap generic power supplies have been known to be over-rated for the power they can handle. There have been some interesting reviews on desktop models for that:

i also have 180watt and it works like champ!!!

 

I really do not think you would have a bad power supply. I purchased an extra 180w power supply for my P150HM (yes I know it comes with a 180w supply) and it is working great. I purchased one of the Targus supplies though. Now that being said if something is working fine with the 120 and stops working with a 180 then I think there is something up. What did you get as far as a 180 can you link it?

This is the one I have it is cheap and works perfect on the P150HM eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices

It is cheap so may be worth a try. I know the 180 works on the P151HM1, I am pretty sure they are the same laptop except for the rubberized finish and usually ship with a smaller GPU stock.

 

Which PSU did you get? It is possible for PSU to cause something like this as it may not be a good enough quality one and have some noise or grounding issues.

I have seen this before with bad battery's and bad PSU... In this case I would say PSU as you 120 works fine and on battery you are fine.

 

This is my PSU

 

is that an adjustable voltage psu? nice work and i have a similar problem. when the psu is connected and i play music via 3.5mm cable to my amp i get horrible static but when i disconnect my computer the static goes away. so whats the deal is my psu just noisy?

 

That's a ground loop

 

Thanks for the responses guys,

The PSU i bought is this one:

AC Adapter Charger For Clevo P150HM (A80) | eBay

But it doesn't look like the picture, ill take a photo when i get home from work and post it up...as for brand, it doesn't have one, it just says "replacement power adapter" or something like that & its lighter then the 120watt...

One thing i did notice, is the 180watt power supply cable is only the "figure 8" end (that goes into the PSU brick) and the power point end doesn't have a ground/earth. (see the picture on the ebay add) and my LITEON 120watt has a different end (guessing its got the one extra with a ground) and power point has the 3 ends for the wall

Looks like its just a eBay cheapy and shouldn't be used in my clevo...

Can I purchase one from a Clevo reseller member here? as in a legit/tested one? if so how much would it cost and how would i proceed with payment? I am interested in getting one that works!

 

Thanks for those links MALIBAL...

Yep so no other issues besides the trackpad flipping out, i wouldn't mind getting a legit 180 watt power supply to test though

Oh one thing i did test and discover, i got the australian version of the KILL-A-WATT and the 120watt PSU sees 120watts sometimes more, around 130 and even spiked to 150 really quickly before, however the 180watt power supply will not go over about 80watts under full load, so as you mentioned, it could be rated higher then what it can actually do?

 

It's normal to see the power reading spike over the output rating due to inefficiencies in the overall converter. That range sounds about right for the 120w.

However, that reading you got from the 180w is interesting. It seems to confirm that it's not actually outputting what it's rated for. If it's only drawing at most 80w from the wall, it may have been a mislabeled lower-output supply. Either that, or it's just faulty and can't output the power it should.

 

where did u buy that think???how many watts??
