17 R5, low performance after removing the battery

Well what adapter you have? I have the GTX 1080 and i9 config but they sent me the 240w but when I got the 330 the performance improved.

What I'm thinking is that all Alienware laptops come with a hybrid mode which allows the laptop to be constantly providing additional power to the adapter to boost preformance but since yours is not there even with the 330w one it still is not going to perform well.

Try going inside the bios and setting the charging mode to Express.

Welcome to the Dell Community @Strokrot 

Hybrid Power Design:

Under a heavy loading environment, the system may be stressed to pull more power than the designed system power profiles allow for.

In order to accommodate the additional power needs under heavy loading, the battery will be triggered to provide additional amounts of power to the system.

This will help explain:

Alienware 15 R3/15 R4/17 R4/17 R5/M15/M17 performance issue or battery drain while AC adapter is connected.

NOTE:

If it is not to expensive I would go with the [ 6-CELL “SMART” LITHIUM-ION (99 WHR) ] as a replacement.

So, basically you are saying I have to buy a new battery to allow my laptop to run at 100% capacity/performance? Is there a way to deactivate this Hybrid Power Design feature and get this extra power from the outlet?

Yes, I have a 240W Power Adapter.

Switching it to a higher wattage wont fry my motherboard?

@Strokrot 

Your system came with 180W, 240W and 330W adapters.

So you can go to a 330W with no problem.

One question!!!

On the bottom of the unit it should have a label with the power requirements.

It will look like 19.5V ~ { 9.23A, 12.3A or 16.9A }

What does yours have { 9.23A, 12.3A or 16.9A } ???

19.5 Volts and 12.3 Amperes

@Strokrot 

Your system requires at least a 240W AC adapter.

Volts x Amps = Watts

19.5 x 12.3 = 239.85 " 240W "

You could use a 330W AC.

But as stated above you would still need a working battery and if you could afford it purchase the  [ 6-CELL “SMART” LITHIUM-ION (99 WHR) ].

I would recommend it.

I has 17r5 ,1070, and had same problems, after changing ac adapter to 330wt, (dell original) performance be coming high, also i checked the consumptions of power, and see 290wt in stress test by aid64, before with 240wt adapter was maximum 230wt, this is without battery!!!

I have an Inspiron 7559 with a standard 130W charger that has the same problem when it's without the battery, will I be able to put a 240W charger in solving the problem?

Hey so yes, as @ejn63 said a working battery should help the issue but I think since your battery is already fine, upgrading to a 240w or higher can really help with the issue.

The equipment has no battery, working only on the AC adapter. But with the 130W standard the system is limited. Will a 240W solve the problem?

Again I say that the equipment has no battery.

Hi @thiagoellis  thank you for sharing update. 

Laptops with no battery are designed to function as Desktops on ac adapter power.

Getting a 330W ac adapter will provide power-on-demand, using the intelligent handshake circuits in both ac adapter and the laptop. This intelligent handshake ensures that laptop is not damaged. 

Hybrid power is disabled when laptop has no battery. Alienware laptops are designed to provide maximum performance, and no battery will limit the top end of a power hungry application's FPS performance capabilities. My Alienware 17 R5 with battery disconnected and on 240W ac adapter power, is happy to run with Hybrid power disabled. My Workstation with Corsair HX750i PSU is used to run power hungry applications. 

Try 330W ac adapter, to see what, if anything, happens on your system. Getting an external GPU (eGPU) enclosure should be considered when running graphic intensive applications.  

Please share an update on progress, so that other users derive benefit from your experience. Thank you. 

I'm having this issue on a Dell Inspiron 7559 A20, not an Alienware. The standard charger is 130W, so would a 240W charger be more than enough?
Because the price of a 330W is much higher and maybe it doesn't justify it, since it is a more modest device.

Yes Im sorry for the late response. 240W is great for it but if a power outage happens, either corrupted data or just waiting till the power comes back to use it again. Also 240w is going to power it alot more than 130w because incase your doing some light gaming it can help to prevent power discharging while charging the battery.
